Chapter 1: Interdisciplinary Higher Education 1 2 3 Martin Davies and Marcia Devlin 4 5 Abstract 6 In higher education, interdisciplinarity involves the design of subjects that offer the opportunity to 7 experience "different ways of knowing" from students' core or preferred disciplines. Such an 8 education is increasingly important in a global knowledge economy. Many universities have begun 9 to introduce interdisciplinary studies or interdisciplinary subjects to meet this perceived need. This 10 paper explores some of the issues inherent in moves toward interdisciplinary higher education. 11 Definitional issues associated with the term "academic discipline", as well as other terms, 12 including "multidisciplinary", "cross-disciplinary", "pluridisciplinarity", "transdisciplinarity", 13 and "interdisciplinary" are examined. A new nomenclature is introduced in the paper to assist in 14 clarifying the subtle distinctions between the various positions. The paper also outlines some of the 15 pedagogical and epistemological considerations which are involved in any move from a traditional 16 form of educational delivery to an interdisciplinary higher education, and recommends caution in 17 any implementation of an interdisciplinary curriculum. 18 1. Introduction 19 The global knowledge economy is the knowledge-based economy where "knowledge 20 technologies"-including knowledge management-produce substantial economic benefits. This is 21 the economy that the higher education sector is now required to service and help to shape. In an 22 increasingly interconnected, globalised world with common issues and challenges, expertise from a 23 range of disciplinary and professional perspectives has become critical to the identification and 24 management of new and emerging global concerns. Examples of global issues that require 25 interdisciplinary study include global warming, water allocation at a time of resource shortage, the 26 AIDS crisis, and the prudent management of financial markets. As the world has become more 27 connected and integrated, interdisciplinarity has gained an increasingly central place in higher 28 education. Although it may be central, this place in higher education may not necessarily be overt, 29 in terms dedicated subject areas. It can also be covert, in terms of time spent on interdisciplinary 30 practices (Chettiparamb, 2007, p. 12) 31 This chapter explores both the different forms and understandings of interdisciplinarity and the 32 ways in which interdisciplinarity might be best integrated into higher education. While 33 interdisciplinary studies are flourishing in some areas of higher education-as the contributions to 34 this book demonstrate-interdisciplinarity studies are far from the norm in higher education 35 globally. A discussion of the term "academic discipline" is outlined in the paper, in the context of 36 an examination of the notion of a "discipline". Following this discussion, the terms 37 "multidisciplinarity", "cross-disciplinarity", "interdisciplinary" as well as the terms 38 "pluridisciplinary" and "transdisciplinary" are examined. Some of the pedagogical issues inherent 39 in a move from a traditional form of education to interdisciplinarity education are outlined, and 40 epistemological considerations relevant to interdisciplinarity are also discussed. The chapter 41 concludes with a section outlining important considerations in preparing for and managing change 42 in higher education that is aimed at increasing the role and place of interdisciplinarity. 43 16 2. What is an Academic Discipline? 1 There is a growing body of literature on the nature of academic disciplines and interdisciplinarity. 2 In a recent extensive critical review of the literature, Aboelela et al. (2007) have determined there 3 are over 500 published papers related to interdisciplinarity in the Health Sciences alone, of which 4 42 articles are concerned with interdisciplinary research and the remainder concerned with other 5 aspects of interdisciplinarity (e.g., examples of interdisciplinary practice) (Aboelela, Larson, 6 Bakken, Carrasquillo, Formicola, Glied, Haas, & Gebbie, 2007). In this section, some distinctions 7 in this field are clarified and a new nomenclature is proposed to understand the distinctions in 8 various options available to a university if it is to go down a path of being "interdisciplinary". In 9 order to explore interdisciplinarity and other variations, it is first necessary to understand the term 10 "academic discipline". 11 2.1 Academic Disciplines 12 The academic disciplines as they are known today are widely considered to be largely discrete and 13 autonomous, although not homogeneous (Becher, 1981). The traditional view of an academic 14 discipline is an area of study 'with its own theories, methods and content ... distinctiveness being 15 recognised institutionally by the existence of distinct departments, chairs, courses and so on' 16 (Squires, 1992, p. 202). An academic discipline has also been defined as 'a branch of learning or 17 scholarly instruction' (OECD, 1972). However, this definition is somewhat circular in that "branch 18 of learning" requires further explanation. Disciplines are generally considered more discrete than 19 "fields of study" or "fields" in that a field is generally outlined when undertaking a course of study 20 in a discipline. Thus, a "field" of study has a wider meaning than "discipline". Discipline experts or 21 practitioners, and universities in general, provide a framework for students by setting out fields of 22 study for students to follow. A "discipline" thus defines and delimits a "field" of study, rather than 23 the other way around. 24 Beyer and Lodahl have defined "disciplines" in more general terms. They suggest that a discipline 25 provides the "structure of knowledge" that trains and socialises members of a university 26 department. This training and socialisation includes the ability to carry out the appropriate tasks of 27 teaching, research, and administration that are germane to the discipline. It also includes the 28 production of relevant research, the process of peer-review, and the development of a system of 29 academic rewards (Beyer & Lodahl, 1976; Reich & Reich, 2006). Becher (1981), likewise, defines 30 disciplines broadly as "cultural phenomena": 'they are embodied in collections of like-minded 31 people, each with their own codes of conduct, sets of values, and distinctive intellectual tasks' 32 (Becher, 1981, p. 109). 33 Following Boisot (1972) and Lattuca (2001), Chettiparamb (2007, pp. 2-3) attributes disciplinarity 34 to three concurrent and simultaneous forces: cultural, organizational and scientific. In particular, 1) 35 man's natural tendency to classify and conceptualise the word around him; 2) the need for science 36 to take advantage of different kinds of knowledge (and the parallel need to ensure that individuals 37 are educated within knowledge areas); and 3) the desire for society to develop economically, which 38 can only be done in a society that is highly structured and organised. 39 2.2 The Traditional View of Academic Disciplines 40 The traditional view of the nature of academic disciplines as discrete and autonomous began with 41 the development of universities in Europe. The earliest universities began with only four 42 disciplines: Medicine, Philosophy, Law and Theology. The Department of Physics at Oxford still 43 retains the name "Department of Natural Philosophy" in recognition of this heritage. The "sciences" 44 17 as they are known today did not exist in earlier times. Over the centuries, increasing specialisation 1 has resulted in more disciplines being added, and by the 1950s one report noted around 1,100 2 scientific disciplines (Schultz, nd. cited in Max-Neef, 2005). More recent attempts to classify 3 academic disciplines have resulted in more, not fewer, "disciplines" being included ("Classification 4 of Instructional Programs," 2000; List of Academic Disciplines," 2007). Codification of academic 5 disciplines is a widespread practice in academic institutions but this codification occurs only at the 6 level of the body of knowledge in a discipline, as opposed to the type of scholarly practices and 7 activities and the behavioural features of its practitioners. The Australian Research Council 8 Research Fields, Courses and Disciplines (RFCD) classification codes are an example of such a 9 codification system. 10 This evolution of academic disciplines continues apace. There are calls to create new academic 11 disciplines from a variety of unlikely candidates, for example, Business Succession Planning and 12 from Genealogy (Ip & Jacobs, 2006; Wagner, 2006). Similarly, there are questions about whether 13 traditional academic disciplines-for example, Accounting-should continue to be described as 14 such (Fellingham, 2006). There have been various attempts to undertake anthropological study of 15 academic disciplines, and to describe these unique cultures, with limited success (Becher, 1981, 16 1989). While there is general agreement about what an academic discipline is, it is also clear that 17 many have porous borders. 18 While academic disciplines are, to some degree, porous, there are certain features that can be agreed 19 upon. The following features are among those often attributed to an academic discipline: 20 • the presence of a community of scholars; 21 • the existence of a tradition or history of inquiry; 22 • the presence of a mode of inquiry that defines how data is collected and interpreted; 23 • the existence of a definition of the requirements for what constitutes new knowledge; and 24 • the existence of a communications network. 25 Of course, the differences among the disciplines are as important as the things that bind them. Art 26 historians, geologists and economists all differ markedly in terms of how they substantiate their 27 knowledge and their methodologies (Hofer, 1997, 2000, 2001). Academic disciplines also differ 28 markedly in regard to standards of justification and evidence, degrees of certitude in what 29 constitutes knowledge, and in their understanding of the structure of knowledge itself. 30 Epistemological issues are discussed further below. 31 Over time, new disciplines naturally gain their independence from their original disciplinary homes, 32 especially once a defined and unique methodology is employed to determine the subject matter of 33 each. For example, Cognitive Science, once the province of philosophers, and part of the discipline 34 of Philosophy (and, in particular, the field of the philosophy of mind), has taken on a life of its own, 35 and is now considered to be on its way to becoming a discipline, if it is not a discipline already. 36 International conferences are held in the new "discipline", there are Centres of Cognitive Science in 37 universities around the world, and there are specialised peer-reviewed journals dedicated to the 38 area. We shall return to this example shortly. 39 There is a view of the disciplines as "horizontally" structured along a continuum, with "hard" or 40 empirical sciences at one end, the "softer" social sciences in the middle, and the "soft" humanities 41 at the other end (see Figure 1 below). In between the extremes (the dotted lines) are various 42 disciplines of a greater or lesser degree of methodological "hardness" or "softness". Figure 1 shows 43 the standard view of the relationship between the disciplines on the "hard-soft" continuum. This 44 18 view has been supported and validated by empirical studies (Biglan, 1973b; Creswell & Bean, 1 1981; Donald, 1986; Sinclair & Muffo, 2002; Smart & Elton, 1978). 2 3 4 5 HARD SOFT 6 Figure 1: The "Hard"- "Soft" Continuum of Academic Disciplines 7 Despite the intuitive appeal of homogeneous, autonomous and discrete disciplines arranged along a 8 continuum, this simple account is clearly not adequate. In particular, it does not fully capture the 9 complexity of academic disciplines. In particular, it does not account for the growth and 10 development of disciplines. There are many instances of an apparent lack of clarity in what might 11 be ordinarily called a "discipline". For example, before WWII, the discipline of Physics was 12 characterised by the quest for immutable and unchanging laws of nature; after the war it became 13 more focussed on industrial applications (Becher, 1981); some parts of Economics and Psychology 14 are empirical ("hard") in nature and others are not. In the 1960s, it was considered important that 15 Psychology was a "hard", empirical discipline (e.g., B. F. Skinner's work); more recently, it has 16 been thought to be more accommodating of alternative positions. It is clear that the simple "hard-17 soft" dichotomy lacks the subtlety to adequately describe some characteristics of the disciplines. 18 Under the traditional notion of academic disciplines as discrete and autonomous entities, there is a 19 standard undergraduate educational pathway for students in countries such as Australia. With few 20 exceptions and double degrees aside, students begin their studies in one of the broad faculty 21 divisions (the sciences or Arts, for example). The student experiences the disciplines within that 22 faculty grouping, and eventually specializes in one of them. This discipline influences students' 23 views about what is known, what is valued, and what is capable of investigation". The discrete 24 nature of disciplines means that by the end of their studies, a student of one may not know much 25 about another discipline. For example, a student of Accounting may not know much about Finance; 26 a Biology student might not know much about Physics; a Psychology student may not know much 27 about Neurology, and so on, though students may have passing familiarity with cognate disciplines. 28 "Disciplinarity", then, describes the traditional view. It is a term used to describe academic 29 disciplines as autonomous and discrete areas of study which do not normally cooperate or 30 coordinate their academic efforts across disciplinary boundaries. Disciplines can be seen as discrete 31 "boxes" (albeit with porous boundaries at times). 32 2.3 Limitations of the Traditional Notion of "Academic Disciplines" 33 As noted by Squires (1992), one of the limitations of the traditional notion of academic disciplines 34 is that it fails to acknowledge that disciplines are not historically fixed; that they evolve and change 35 over time. Like everything else, of course, academic disciplines are culturally and historically 36 situated. In addition, disciplines are not defined by one attribute but by many, and the relative 37 emphasis on these different attributes can differ from discipline to discipline, and even within 38 disciplines. Again, a discipline such as Psychology has undergone great changes from its inception 39 as an introspective discipline with the work of William James, Sigmund Freud, Carl Jung and 40 others, to its current empirically-based concerns, though there remain different "branches" where, 41 for example, psychoanalytic research is still discussed, and more speculative ideas (e.g., in 42 Physics Chemistry Biology Economics Psychology Humanities 19 philosophical psychology) are considered. There have been attempts to redefine the notion of 1 "academic discipline" to recognise these points (Becher, 1989; Biglan, 1973b; Donald, 1986; Kolb, 2 1981; Squires, 1992). 3 Squires (1992) has helpfully defined an academic discipline in terms of three "dimensions": their 4 object (what they are concerned with, their current problems and issues); their stance (their current 5 epistemic concerns, that is, what they consider to be their framework of knowing and how they do 6 things-their methodology); and their mode (that is, how they reflexively consider themselves as a 7 discipline, for example, the extent to which they are "normal", "mature", or "revolutionary" in the 8 Kuhnian sense). Many disciplines go through periods of "normal" science (that is, business-as-usual 9 using an unchallenged, commonly agreed-upon theoretical framework), to "revolutionary" periods 10 where these frameworks are questioned, thrown into doubt and/or replaced, for example, 11 Einsteinian physics replacing Newtonian physics (Kuhn, 1962). 12 Squires has a more sophisticated understanding of "discipline" that acknowledges these dimensions. 13 He claims that all disciplines are 'multidimensional spaces which define, protect and enlarge 14 themselves along any of those dimensions, and in so doing, come into conflict or cooperation with 15 other disciplines' (Squires, 1992, p. 203). See Figure 2 below. 16 17 Figure 2: Squires' (1992) Account of a Discipline 18 On Squires' account, friction and permeation can occur at the borders of disciplines, and influences 19 can be widespread among them. An example of the latter is the empirical methodology of the hard 20 sciences. This has had a lasting effect on other disciplines that are traditionally remote from the 21 concerns of the sciences (for example, disciplines such as Linguistics). However, powerful 22 influences on disciplines of this nature are seldom bi-directional. 23 More recently, Aram has described disciplines as 'thought domains-quasi-stable, partially 24 integrated, semi-autonomous, intellectual conveniences-consisting of problems, theories and 25 methods of investigation' (Aram, 2004, p. 380; Chettiparamb, 2007, p. 3). The description of a 26 discipline as an "intellectual convenience" may seem overly instrumentalist, but it does capture the 27 "looseness" of discipline boundaries. Useful definitions that recognise the subtlety of the notion of 28 "discipline" have been provided recently by others (Parker, 2002; Turner, 2000a). For a review, see 29 Chettiparamb (2007). 30 2.4 Multidisciplinarity 31 Multidisciplinarity recognises the fact that there are many discrete and autonomous disciplines. In 32 higher education, while undergraduate students normally specialise in one discipline, they can study 33 several over the course of a typical degree program. For example, an Accounting student also 34 20 studies some subjects in Finance in addition to accounting subjects, and may also study Economics, 1 or even subjects in unrelated disciplines, such as History or Music. 2 In terms of research, in some areas of investigation there may be multidisciplinary contributions 3 from several discipline areas to a joint research program. Often, however, in practice, each of the 4 disciplines contributes from its own perspective. In both a practical and intellectual sense, each of 5 the disciplines stands alone. Multidisciplinarity has been described more simply as the view that: 6 'everyone [does] his or her thing with little or no necessity for any one participant to be aware of 7 any other participant's work' (Petrie, 1976, p. 9). Multidisciplinarity is simply the co-existence of a 8 number of disciplines. 9 2.5 Cross-Disciplinarity 10 Cross-disciplinarity is another variation of disciplinarity. The term cross-disciplinarity is often 11 confused with "interdisciplinarity" but in the former, a topic normally outside a field is investigated 12 with no cooperation from others in the area of study. Two examples are the physics of music and 13 the politics of literature ("Interdisciplinarity," 2007). While sometimes informative and interesting, 14 this type of inquiry involves the use of techniques and tools from those normally that are foreign to 15 those used to study the phenomenon under consideration. Cross-disciplinary work rarely involves 16 any transfer of methodologies. Taking one of the examples above, musicians do not necessarily 17 learn any physics and physicists do not necessarily learn much about music. 18 3. Interdisciplinarity 19 Interdisciplinarity has been described as 'a remedy to the intellectually deadening effects of 20 excessive specialization'("Interdisciplinarity," 2009). A number of sophisticated definitions are 21 available in the literature (Boisot, 1972; Chandramohan & Fellows, 2009; Heckhausen, 1972; 22 OECD, 1972). One recent definition is given as follows: 'the emergence of insight and 23 understanding of a problem domain through the integration or derivation of different concepts, 24 methods and epistemologies from different disciplines in a novel way' (Rogers, Scaife, & Rizzo, 25 2005, p. 3). The key terms here are "integration" and "novel". As will be demonstrated, it is 26 insufficient merely to look at an issue from the point of view of different disciplines. A number of 27 types of "integration" are possible, and therefore a number of different kinds of interdisciplinarity, 28 as outlined below. 29 Building on an earlier paper (Davies & Devlin, 2007b), we claim that there are a number of variants 30 of interdisciplinarity that can be located on a continuum from benign to radical. Here we propose 31 new nomenclature for these variants. The new terms: relational, exhange and modification 32 interdisciplinarity are introduced below, alongside the standard terminology of pluridisciplinarity 33 and transdisciplinarity. While disciplines have traditionally been regarded as discrete and 34 autonomous, interdisciplinarity recognises the subtleties of the nature of academic disciplines. The 35 argument in this chapter is that there are a number of possible forms that interdisciplinarity can take 36 and that naming them can be useful for discussion. Some unique terminology is provided in this 37 chapter to assist in understanding the differences. 38 3.1 Relational Interdisciplinarity 39 At the benign end of the interdisciplinary spectrum, interdisciplinarity is regarded as elective 40 subjects taken from a variety of disciplines that in some way relate to a general topic-an example 41 might be Women's Studies. Here there are 'two or more disciplines ... contributing their particular 42 disciplinary knowledge on a common subject' (Garkovich, 1982, p. 154; McGrath, 1978). Related 43 topics can be-and frequently are-discussed from different angles or points of view. This variant 44 21 of interdisciplinarity might be referred to as relational interdisciplinarity and its similarity to 1 multidisciplinarity is clear. The differences are that, in multidisciplinarity, there is no 2 acknowledgement of the work of others at all; whereas in relational interdisciplinarity, there is an 3 explicit acknowledgement of-but no implicit willingness to learn from others. Heckhausen (1972) 4 refers to this form as "indiscriminate interdisciplinarity", that is, the form of interdisciplinarity that 5 often results in "curriculum mix-ups" (Heckhausen, 1972, pp. 87-89). This form of 6 interdisciplinarity amounts to looking at an issue from different disciplinary perspectives, with little 7 or no attempt to integrate those perspectives in any meaningful sense. 8 3.2 Exchange Interdisciplinarity 9 Moving along this continuum of variants of interdisciplinarity, another variant involves 10 'entrench[ing] discipline boundaries' yet 'leaving open mutually radical dialectic-critique of 11 opponent territories' (Davidson, 2004, p. 308; Rowland, 2001). This view implies critique and the 12 critical exchange of views while maintaining robust disciplinary integrity. This variant might be 13 referred to as exchange interdisciplinarity. Heckhausen calls this variant, "psuedo-14 interdisciplinarity" because disciplines may share analytical tools, but otherwise remain untouched 15 by the exchange of views between discipline experts (Heckhausen, 1972, pp. 87-89). In this variant, 16 there is both an explicit and implicit acknowledgement of other disciplines, and a critical exchange 17 of views (and possibly methodological tools), however there is no real integration toward a 18 common purpose. This might be considered a curriculum mix-up "with attitude". Participants to 19 such an exchange are willing to critique, or perhaps even attack, each other's positions from the 20 point of view of their own. But they are unlikely to develop anything novel; nor integrate the 21 insights of others toward a mutually common aim or objective. 22 3.3 Pluridisciplinarity 23 Another variant of interdisciplinarity further along the continuum is sometimes known as 24 pluridisciplinarity (Max-Neef, 2005). This variant requires two or more disciplines to combine their 25 expertise to jointly address an area of common concern. Heckhausen calls this "composite 26 interdisciplinarity" (Heckhausen, 1972, pp. 87-89). Pluridisciplinarity is often seen in areas of study 27 where the topic under investigation is too complex for a single discipline to address. Examples 28 include the AIDS pandemic and climate change. Topics such as these require the efforts of many 29 specialists. Indeed, discipline experts have to learn from each others' expertise; the nature of the 30 problems under consideration demands that this occurs. 31 An issue such as "land use", for example, is seen differently from economic, geological and 32 environmental perspectives. In the health sciences, a pressing social concern such as obesity 33 requires the integrated views of behavioural scientists, molecular biologists, and mathematicians 34 (Aboelela et al., 2007). This "integration" satisfies one of the two conditions of true 35 interdisciplinarity (the other condition is developing something "novel" from this integration). 36 Where in disciplinarity and multidisciplinarity there is no cooperation at all between disciplines-37 and in relational and exchange interdisciplinarity there is minimal interaction, and only a degree of 38 acknowledgement-pluridisciplinarity involves an explicit degree of cooperation. 39 A recent example of pluridisciplinarity is the new "discipline" of Cognitive Science. Here 40 philosophers, linguists, computer scientists, artificial intelligence experts, neurologists and brain 41 scientists cooperate in the production of papers for dedicated conferences and journals, for example, 42 Journal of Consciousness Studies and Behavioral and Brain Sciences. This cooperation is toward an 43 understanding of topics of common concern, in this case, the scientific study of consciousness. 44 However, while there is a strong amount of cooperation, a common objective, and genuine mutual 45 22 interest in pluridisciplinarity, there is no sense in which, say, computer scientists, neurologists, and 1 philosophers do research that is independent of their respective disciplinary areas. Entire 2 encyclopaedias are now published in the area of Cognitive Science, but they are still partitioned into 3 the relevant (and discrete) discipline areas (Wilson & Keil, 1999). The degree of integration is 4 limited to merely discussing a common problem, it does not extend to integrating the disciplines 5 toward a novel outcome. As Rogers, et. al., put it: 6 In practice, many self-styled interdisciplinary enterprises actually work at the level of being 7 multidisciplinary (or pluridisciplinary): where a group of researchers from different 8 disciplines cooperate towards a common goal, but continue to do so using theories, tools, and 9 methods of their own discipline, and occasionally using the output from each other's work. 10 They remain, however, essentially within the boundaries of their own disciplines both in terms 11 of their working practices and with respect to the outcomes of the work (Rogers et al., 2005, p. 12 3). 13 There is often a transfer of techniques and methodologies in pluridisciplinarity research, but as 14 Rogers et. al., note, this is quite different from using the perspectives of different disciplines to 15 provide insight in a novel way. In pluridisciplinarity, the research is discipline-based, and 16 researchers may discuss with, and inform each other about, an issue that is of common concern 17 from their different respective academic positions (see Figure 3 below). For example, unlike in the 18 past, philosophers of mind now openly discuss empirical methods used by neuroscientists, and 19 neurologists now openly discuss philosophical terminology and concerns (Dennett, 1991). There is 20 also a seriousness of purpose in such exchanges. This is not "pseudo" interdisciplinarity, or 21 "indiscriminate" interdisciplinarity, so it is distinct from the versions of interdisciplinarity 22 mentioned earlier. Participants in such projects have a genuine willingness in the perspectives and 23 insights of academics from other domains. 24 25 26 27 Figure 3: Pluridisciplinarity (Cooperation between disciplines) 28 (Max-Neef, 2005, p. 7) 29 However, even in what would seem to be a paradigmatic example of interdisciplinarity-such as 30 Cognitive Science-true interdisciplinarity is difficult to achieve in practice, and has been described 31 as an "elusive goal" ( Rogers et al., 2005, p. 3). This is because, while one of the conditions of true 32 interdisciplinarity has at least been partially satisfied (integration), the second (developing novel 33 outcomes), has not. True interdisciplinarity, it seems, is difficult to achieve. 34 In Heckhausen's account, there are degrees of composite interdisciplinary influence, so this 35 category of interdisciplinarity in itself represents a spectrum. In some areas, there is considerable 36 overlap on subject matter between different disciplines; in other areas, there may be no overlap at 37 all, or only partial overlap. Where there is "partial" overlap, he describes this as "supplemental 38 interdisciplinarity" (e.g., the example of Cognitive Science). Supplemental interdisciplinarity occurs 39 'at the borderlines of disciplines' (Chettiparamb, 2007, p. 20). Where there is more substantive 40 overlap, and a legitimate need to solve a pressing problem-e.g., different disciplines addressing 41 the AIDS crisis, obesity, or global warming-this is considered true "composite" interdisciplinarity 42 (Heckhausen, 1972). 43 23 Figure 3 shows the autonomy of discrete disciplines that may cooperate with each other when 1 circumstances demand. This cooperation may involve the sharing of methodologies, techniques or 2 concepts or it may involve a pressing need to solve a problem using insights from various 3 disciplinary perspectives. This diagram should perhaps be shown with shaded two-way arrows to 4 indicate the degree of strength of disciplinary overlap. 5 There is a plausible case to be made for pluridisciplinary relationships between the disciplines in 6 higher education. Some issues and topics appropriate for undergraduate university level study are 7 simply too complex to be properly investigated within a single traditional discipline. If 8 interdisciplinary relationships are fostered, traditional disciplinary structures can be retained, and 9 interdisciplinary relationships formed for the purposes of teaching and learning. These relationships 10 might go some way to promote critical dialogue between the disciplines of complex topics that are 11 beyond the resources of individual disciplines alone. 12 Petrie (1976) makes an interesting point in this context. He notes that the history of the disciplines 13 teaches us that disciplinary specialists themselves seek interdisciplinary relationships when the 14 demands of their subject warrant it, and not before. Certain conceptual issues demand new 15 perspectives to provide breakthroughs. These insights can certainly come from different disciplines. 16 The history of thought provides many examples where disciplinarians have themselves welcomed 17 interdisciplinary relationships. Biology needed Physics at a certain stage of its development. 18 Ecologists use mathematics when necessary. Philosophers of mind began to seek relationships with 19 neuroscientists and computer scientists when their a priori speculations about internal 20 representations led to a need to understand what an internal "representation" might be. There are 21 numerous cases in which the nature of a problem has necessitated the insights of another discipline 22 (Petrie, 1976). Interdisciplinarity, therefore, occurs naturally among disciplinary specialists at times. 23 Like relational interdisciplinarity, however, pluridisciplinarity is not especially different from what 24 typically occurs in university education. It is something academics do as a matter of course. 25 Interdisciplinary exchanges-such as those presupposed under pluridisciplinary relationships-26 occur as a matter of course. 27 3.4 Modification Interdisciplinarity 28 Moving further along the continuum, there is yet another variant of interdisciplinarity. Unlike 29 multidisciplinarity-where disciplinarians need not discuss things with each other-this variant 30 requires 'more or less integration and even modification of the disciplinary sub-contributions while 31 [an] inquiry is proceeding. With this version, there is often coordination from a higher hierarchical 32 level to the levels lower down. The disciplines at the lower levels are subordinated to the 33 coordinating level higher up. In this variant of interdisciplinarity, different participants need to take 34 into account the contributions of their colleagues to make their own contribution' (Petrie, 1976, p. 35 9). 36 Within this view, the latter point is crucial as one of the criticisms of some interdisciplinary work is 37 that it is "interdisciplinary" in name only. This variation might be called modification 38 interdisciplinarity or, in Heckhausen's terms, "unifying interdisciplinarity" (Heckhausen, 1972, pp. 39 87-89). This variant is outlined in Figure 4 below. Modification interdisciplinarity involves more 40 than cooperation and integration. It requires that disciplines are changed in some way by the 41 association with other disciplines, and that there is a degree of consistency in the disciplines in 42 terms of their subject matter. The arrows below indicate that the hierarchical concerns are 43 influencing in some way the structural integrity of disciplines below. An example of this might be 44 when Medicine harnesses the concerns of Biology, Physics and Psychology to serve "higher" 45 24 pragmatic purposes, or when disciplines such as Agriculture, Forestry and Commerce serve the 1 needs of disciplines such as Politics (Max-Neef, 2005). In this instance, something "novel" is 2 occurring. A coordinating discipline is guiding and integrating the insights of disciplines lower 3 down. As noted earlier, this is certainly not yet happening in disciplines such as Cognitive Science, 4 and therefore modification interdisciplinarity represents a distinct, and more extreme, variant on the 5 positions already mentioned. 6 7 Figure 4: Modification Interdisciplinarity (Coordination from a Higher Hierarchical Level) 8 (Max-Neef, 2005, p. 7) 9 3.5 Transdisciplinarity 10 Moving yet further along the continuum of variants of interdisciplinarity, at the extreme end is a 11 view of interdisciplinarity as involving the 'collapse of academic borders and the emergence of a 12 new discipline' (Davidson, 2004, p. 308; Rowland, 2001, p. 3). This is sometimes known as 13 transdisciplinarity (Max-Neef, 2005). However, this extreme variant of interdisciplinarity may be 14 more a theoretically possible position than a practical reality. It is not clear what would count as an 15 example of a new discipline that has emerged from a process of transdisciplinary evolution and left 16 its parent discipline behind, that is, emerged from traditional disciplines that have since "dissolved". 17 To take the case of Cognitive Science mentioned earlier, this has certainly emerged as a new quasi-18 discipline, but in no sense has there been dissolution of its parent disciplines: Philosophy, 19 Neuroscience, Computer Science -and nor is it likely that this would ever occur. 20 There are other unanswered questions with this variant of interdisciplinarity. Dissolving academic 21 boundaries would seem to go against the gains won in terms of the basic research productivity of 22 individual disciplines. But, even if this is considered desirable, one wonders how this variant would 23 work in practice. And how, in a practical sense, would disciplines continue work done in dedicated 24 disciplinary areas of concern if boundaries were "dissolved"? What does the dissolving of 25 boundaries mean exactly? How would disciplinary integrity be maintained? How would traditional 26 academic concerns be maintained in attempts to reorganise the curriculum to meet more pressing 27 global challenges? If boundaries between disciplines are ever dissolved it becomes unclear to what 28 extent traditional disciplines would survive. 29 The various forms of "disciplinarity" can be represented as follows (see Figure 5 below): 30 31 25 1 BENIGN 2 Relational 3 Exchange 4 Pluridisciplinarity 5 6 Disciplinarity Multidisciplinarity Cross-Disciplinarity Interdisciplinarity 7 Modification 8 Transdisciplinarity 9 10 EXTREME 11 Figure 5: Various Forms of "Disciplinarity" 12 Figure 5 shows the various forms of disciplinarity (horizontal axis) with the vertical axis showing 13 the forms of interdisciplinarity along a continuum from benign to extreme. 14 There is a considerable literature indicating that interdisciplinarity, in its various forms, is 15 widespread in a diverse range of traditionally academic domains. These include: Health Sciences 16 (Aboelela et al., 2007); Engineering (Froyd & Ohland, 2005); Sociology (Garkovich, 1982); Higher 17 Education (Davidson, 2004; Field & Lee, 1992b; Kezar, 2005; Newell, 1992; Petrie, 1976; 18 Wolman, 1977); Ecology (Golde & Gallagher, 1999), Music (Ellis & Fouts, 2001); Environmental 19 Studies (Steiner & Posch, 2006); Community Studies (Suarez-Balcazar, Hellwig, Kouba, Redmond, 20 Martinez, & Block, 2006); Management (Tress & Tress, 2005); and Science (Wolman, 1977). In 21 addition, there have been sustained discussions on the role of interdisciplinarity in academic 22 research (Feller, 2006; Reich & Reich, 2006; Schommer-Aitkins, Duell, & Barker, 2003). The 23 academic literature on interdisciplinarity is volumous. For a recent publication, see Chandramohan 24 and Fellows (2009). 25 However, it is not often clear from this literature just what type of "interdisciplinarity" is under 26 discussion-the term "interdisciplinary" is often used without definition and, therefore, without 27 much clarity. Nor is it always clear which variant(s) is/are desirable, and under which contexts the 28 variant(s) of interest might be applicable, or useful, (though see Chettiparamb, 2007, for a useful 29 account of the vagueness and inprecision of existing terminology). It is hoped that the nomenclature 30 outlined above will contribute to clarifying further discussions in this area. 31 4. Pedagogical and Epistemological Considerations 32 This section considers some of the implications of interdisciplinarity for higher education teaching 33 and learning. Given that some interdisciplinarity will be desirable in a global knowledge economy, 34 the questions of how best to incorporate it into students' learning experiences are key considerations 35 in a changing global context. There is a commonsense case for suggesting that the best education 36 that can be provided to university students is a sound discipline-based education, with opportunities 37 for interdisciplinarity. The appropriate mix between local, disciplinary content and interdisciplinary 38 26 content would be critical if this argument was accepted. An education that is too broad might not 1 allow for sufficient expertise in the core discipline for an adequate appreciation of when 2 interdisciplinary work is needed and when it is not. Sufficient local disciplinary content will ensure 3 that students themselves see the need for interdisciplinary understanding when the occasion 4 demands it, just as disciplinarians seek interdisciplinary relationships when they see a need to do so. 5 The following epistemological issues deserve attention in any move toward interdisciplinary higher 6 education. 7 4.1 The Issue of Cognitive Maps 8 It is well known that different disciplines have their own way of viewing the world. These ways of 9 viewing the world are also known as mental models, cognitive maps, frameworks, or "paradigms" 10 (Kuhn, 1962). Individuals understand the world in terms of the cognitive models they possess; in an 11 important sense they "see" things differently to those with different cognitive models. Disciplinary-12 based concepts are necessary for viewing the world in a particular way. In the normal course of 13 events in higher education, students learn these cognitive maps when they are inducted into a 14 discipline-this is part of what it means to become "educated". As Davies and Devlin (2007b) point 15 out, once a student has learned a discipline-specific cognitive map, it becomes difficult for the 16 student so inducted to "see" things any other way. Unless one learns music theory, for example, it is 17 difficult to recognise a plagal cadence for what it is; without music theory, one may just hear 18 sounds. As Hanson puts it, 'the visitor [to the laboratory] must learn some physics before he sees 19 what the physicist sees' (Hanson, 1975, p. 17). Polanyi outlines the way in which a medical student 20 comes to "see" in a new way. His example of a medical student attending a course in the X-ray 21 diagnosis of pulmonary diseases illustrates the notion of 'ways of seeing the world': 22 ... He watches, in a darkened room, shadowy traces on a fluorescent screen placed against a 23 patient's chest, and hears the radiologists commenting to his assistants, in technical language, 24 on the significant features of these shadows. At first, the student is completely puzzled. For he 25 can see in the X-ray picture of a chest only the shadows of the heart and ribs, with a few 26 spidery blotches between them. The experts seem to be romancing about figments of their 27 imagination; he can see nothing that they are talking about. Then, as he goes on listening for a 28 few weeks, looking at ever-new pictures of different cases, a tentative understanding will 29 dawn upon him; he will gradually forget about the ribs and begin to see the lungs. And 30 eventually, if he perseveres intelligently, a rich panorama of significant details will be 31 revealed to him: of physiological variations and pathological changes, of scars, of chronic 32 infections and signs of acute disease. He has entered a new world. He still sees only a fraction 33 of what the experts can see, but the pictures are definitely making sense now and so do most 34 of the comments made on them (Polyani, 1973, p. 101). 35 But concepts are not just important in seeing specialized things in the disciplines; they are also 36 important for common, everyday "seeing". The following example from H. I. Brown (1977) makes 37 this clear: 38 Consider a relatively common, everyday instance of perception such as my seeing my 39 typewriter. Now, in order to see that this object is a typewriter it is not sufficient that I just 40 look at it; it is necessary that I already know what a typewriter is. Simply glancing at objects 41 with normal eyesight will undoubtedly stimulate my retina, initiate complex electro-chemical 42 processes in my brain and nervous system, and perhaps even result in some conscious 43 experience, but it will not supply me with meaningful information about the world around me. 44 In order to derive information from perception it is necessary that I be able to identify the 45 27 objects that I encounter, and in order to identify them it is necessary that I already have 1 available a relevant body of information (Brown, 1977, pp. 81-82). 2 Even ordinary, everyday "seeing" requires conceptual resources of some kind. The phenomenon of 3 the "theory dependence of observation" (the notion that "seeing" requires a battery of theoretical 4 concepts) and the notion of "cognitive maps" occurs, without exception, in all academic disciplines 5 (Polyani, 1973). This being the case, a focus on interdisciplinarity raises challenges for higher 6 education students and higher education providers. 7 If interdisciplinarity is part of a student's higher educational experience, this will, by necessity, put 8 limits on what can be accommodated within a degree program. It will naturally result in fewer 9 topics being taught and learnt in traditional, discipline-based ways. However, disciplinary "depth" 10 is important to ensure that students develop the required cognitive maps ("paradigms") in both 11 disciplinary and interdisciplinary studies. One of the great ironies of moving toward 12 interdisciplinary higher education is the potential sacrifices that have to be made: "depth" in core 13 discipline areas run the risk of being compromised in the pursuit of "breadth" achieved through 14 interdisciplinarity. 15 Careful consideration and management of the pedagogical implications around cognitive maps are 16 necessary as, without this, it is possible that some students may find it challenging to learn the 17 cognitive maps in both the core discipline(s) and the interdisciplinary studies. Arguably, 18 undergraduate higher education should provide education that both prepares students for the 19 changing world of employment, and that provides a pathway into graduate programs. According to 20 Golde and Gallagher (1999), depth of understanding is critical for those leaving university after 21 undergraduate studies to take up a profession as well as for intending graduate students who will 22 have to eventually make research contributions. But in a time-pressed curriculum, careful 23 consideration must be given to how this is achieved in practice when more attention is devoted to 24 interdisciplinary studies. University pedagogy around interdisciplinarity must be able to 25 accommodate both development paths. This is certainly a challenge. 26 4.2 The Issue of Disciplinary Language 27 Disciplinary language is another important point related to the notion of cognitive maps. It has been 28 recognised that in addition to providing the requisite cognitive maps for students, a discipline must 29 also teach a distinct, discipline-specific vocabulary(ies). This raises a number of pedagogical issues. 30 It is as important to teach the language and technical terms of the disciplines, as it is to teach the 31 methodologies, procedures and concepts. Indeed, they cannot be taught without the language. There 32 are significant differences in language, even within disciplines that are naturally grouped together. 33 For example, the language of Accounting is very different from the language of Management, 34 Finance or Law. In disciplines not usually grouped together, these differences are even more 35 pronounced. The language of Accounting, for example, is very different from the language of 36 Chemistry or History. 37 This raises significant epistemological, as well as practical, challenges for academic teaching staff 38 and for students. Some of the disciplinary "vocabularies", and the assumptions behind them, are 39 impossible to compare with vocabularies from other disciplines. For example, the term "mass" 40 means something quite different to a Physicist than it does to an Engineer or Architect. Further, the 41 notion of a "fact" or "evidence" are largely matters of disciplinary definition. If there are 42 differences in the use of single words, it is likely that differences in the understanding of theoretical 43 concepts will be vast (Feyerabend, 1993). 44 28 The language of disparate disciplines may need to be explicitly taught in interdisciplinary university 1 environments. While achieving breadth and depth of study is not an inconsistent aim, it is very 2 challenging to achieve without risking the loss of the strengths of a well-grounded education in the 3 language of single disciplines. An inadequate background and understanding for both employment 4 and graduate study can be the result of mixing the unique languages of Commerce and Engineering, 5 for example, if not undertaken with care. Students will need to graduate from university with the 6 appropriate discipline-specific vocabulary in each of the disciplines in which they have studied 7 (Davies and Devlin, 2007b). 8 4.3 Interdisciplinarity and Idea Dominance 9 Petrie (1976a) has claimed that a central feature needed for interdisciplinary success in research, but 10 also-albeit to a lesser extent-teaching, is idea dominance. Viable projects require a key "idea" 11 without which, success of the project is threatened. It has been noted that over 50 percent of 12 interdisciplinary collaborations fail (Doz, 1996; Kezar, 2005). Failure might be because of 13 inconsistent or incompatible key ideas, or because no key idea emerges. The key idea needs to be 14 mutually agreed upon as being important by all involved. In teaching, dominant ideas are closely 15 aligned with eventual success and achievement in results that all parties to a project or curriculum 16 regard as being illuminating, and as offering some degree of intellectual progress. 17 In contrast to interdisciplinary settings, in independent, "traditional" disciplines, idea dominance is 18 not a critical issue. The reason for this concerns the history of the discipline. The ideas that, for 19 example, Economists, Engineers or Psychologists regard as being important are, over time, filtered 20 from weaker ideas and the latter are abandoned. The dominant ideas become viable and become the 21 focus of investigation and learning, that is, of research and teaching, respectively. 22 However, interdisciplinarity is different. By necessity, and by definition, a variety of ways of 23 seeing, cognitive maps and vocabularies are involved. With issues such as "global warming", for 24 example, the problem or idea is mutually agreed upon as being important by participants from 25 various disciplines. However, these cases are rare. 26 In terms of pedagogy, the concept of idea dominance highlights the importance of students coming 27 from interdisciplinary undergraduate studies with a clear idea of the dominant ideas of their 28 discipline(s). Graduates should be able to distinguish ideas that belong to certain disciplines from 29 those that are interdisciplinary in nature and to recognise a dominant idea from a weaker idea. They 30 must also be able to raise appropriate questions, that is, "legitimate" questions from the perspective 31 of their discipline, in order to critique ideas from both disciplinary and, if appropriate, 32 interdisciplinary perspectives (Davies and Devlin, 2007b). This is a hard task, and a hard ask, as 33 well. 34 4.4 The Effects of Breadth on Depth 35 It is likely that students will usually want to study a discipline in which they are interested and/or in 36 which they believe they have some natural talent. For example, students who have skills in 37 mathematics are likely to be attracted to the study of Mathematics, Physics, Engineering or similar 38 subjects. Likewise, students with talents in language-rich subjects are likely to want to study in the 39 Humanities, Law, the Social Sciences, and related areas. Therefore, if interdisciplinary study is, or 40 becomes, compulsory at an institution, this may disadvantage students who do not have broad 41 interests. It has been noted that: '... disciplinary competence is sometimes at odds with broad 42 interests and imaginative speculation' (Petrie, 1976, p. 10). These observations may be more 43 29 relevant to research efforts than to the teaching and learning arena but they are worth noting in the 1 latter context. 2 There is evidence that individuals who are outstanding in a particular discipline-as opposed to 3 being very good-tend to be very narrowly focussed in their skill area. Petrie (1976) asserts that: 4 '...one tends to see good disciplinarians uninterested in interdisciplinary efforts, and many who are 5 interested seem to have marginal disciplinary competence' (Petrie, 1976, p. 10). It is possible that 6 becoming an excellent disciplinarian demands undivided focus. Expertise is also the result of 7 substantial amounts of training, and the empirical evidence suggests that this training is not 8 transferable (Chi, Glaser, & Farr, 1988; Johnston, 2003). 9 Johnston (2003) claims that disciplinary experts perceive 'meaningful patterns in their own domains 10 better than non-experts. They also use more higher order principles to solve problems, work faster 11 and more accurately, are better self-monitors, more easily comprehend the meaning of data, 12 recognise the relative weighting of variables and have better domain-specific short and long term 13 memory (Johnston, 2003). It may be that expertise is a necessary requirement in disciplinary studies 14 in order for "excellence" in a discipline to occur. This degree of specialisation, single-mindedness 15 and focus required for expertise to occur brings challenges in a university that has the stated aim of 16 pursuing interdisciplinary education. However, as Marginson (2007) has noted "expertise" among 17 mature scholars and "expertise" among undergraduate students are very different notions (pers. 18 com. 15/6/07). 19 The balance between disciplinary focus and interdisciplinary relationships is difficult to navigate 20 practically and demands careful judgement. As noted elsewhere: 21 If one is not ... extremely adventurous and extremely interested in the project, the rewards 22 which accrue simply due to disciplinary competence are likely to pull an [extremely 23 competent] individual away from the interdisciplinary effort. Likewise, the person of 24 extremely broad interests but lesser disciplinary talent may feel the project is going well, when 25 it, in fact, never gets beyond the superficial (Petrie, 1976, p. 11). 26 While cutting edge work does go on in the margins of disciplines, basic and foundational work 27 remains within a discipline. Students need enough exposure to key disciplines to learn key ideas, 28 and to be able to move outside their discipline to obtain interdisciplinary perspectives when 29 necessary or appropriate. Again, this is challenging to achieve in higher education. 30 4.5 Valuing Interdisciplinarity within the Institution 31 Another important pedagogical issue is the institutional setting in which interdisciplinary work goes 32 on (Petrie, 1976). It is important to set up institutions appropriately for interdisciplinary exchanges. 33 More specifically, an appropriate system of rewards and institutional support, promotion, seed 34 funding, release time, teaching and innovation grants and recognition, and the like are necessary in 35 order that purposeful and directed interdisciplinary work in teaching and learning can occur. These 36 rewards need to be directed specifically to interdisciplinary work. At present, the principal 37 recognition and rewards systems for academic staff at most universities are by means ofthrough 38 disciplinary channels such as publication in top-tier disciplinary journals, evidence of having 39 advanced their discipline, teaching awards for teaching undertaken in a discipline, and so on. 40 While there is some evidence that this is beginning to change with, for example, the emergence of a 41 number of interdisciplinary journals, in the meantime, staff existing recognition and rewards 42 systems will continue to drive behaviour and interdisciplinary work may not flourish. Without the 43 necessary institutional policy settings for interdisciplinarity, students, too, may perceive that the 44 30 work that "matters" is being done in the disciplines and not the inter-disciplines. In such 1 circumstances, there is a risk that interdisciplinary work might be seen as token parts of the 2 educational experience and may not be taken seriously (Davies and Devlin, 2007b). 3 5. Preparing for and Managing Change in Higher Education 4 As an increasing number of universities begin to consider (or, in some cases, reconsider) moving 5 toward interdisciplinary higher education, issues related to change management become critical. 6 There are a number of considerations in preparing for and managing change if the traditional 7 disciplinary focus of universities begins to shift to a more interdisciplinarity focus. This chapter 8 concludes with a brief outline of some of these challenges and some ways in which they might to 9 managed and/or addressed. 10 • Induction and preparation of students for entry into new disciplines: When students take 11 subjects outside the broad discipline area towards which they may have a natural inclination 12 and in which they have chosen to focus their efforts, particular attention must be given to the 13 preparation of students for such multidisciplinary and interdisciplinary experiences. Because 14 students may not be naturally inclined toward, or adequately prepared for, these subjects, 15 they are likely to need explicit induction into the academic discourse of unfamilar 16 disciplines. This is particularly important if students are taking interdisciplinary subjects that 17 are very different from their core discipline(s). It should not be assumed that, for example, a 18 student undertaking a Physics major can seamlessly adapt to studying Art History. 19 • Language checklists: The requisite vocabularies are likely, in many cases, to need to be 20 explicity taught within each disciplinary and interdisciplinary setting. The preparation and 21 use of "checklists" or glossaries of key terms designed for each discipline and appropriate to 22 each level of study might be helpful. These would be useful to both students focusing in the 23 disciplines concerned and to students taking interdisciplinary subjects. 24 • Cognitive maps: Induction into an academic discourse and particular way of knowing and 25 seeing the world will, of course, take much more than checklists. As a pre-cursor, it may be 26 necessary for academics from Faculty disciplines to devise minimal levels of disciplinary 27 competence in the cognitive maps required for a graduate from each discipline so that a 28 staged process toward building those maps may be possible through disciplinary and 29 interdisciplinary study. The introduction of "bridging" or intensive preparatory programs 30 that are integrated into the curriculum may need consideration. And clearly, particular 31 attention will need to be paid to the ways in which assessment practices will ensure and 32 uphold standards and help determine student understanding and readiness to advance to the 33 next level of study and to graduate. 34 • Benchmarking disciplinary knowledge: It may also be necessary to put in place mechanisms 35 to benchmark standards with students and/or graduates studying elsewhere where an 36 interdisciplinary focus is not emphasised in the curriculum. This would ensure that students 37 participating in interdisciplinary higher education are not being penalised in terms of their 38 learning, or being given a less rigorous education in core discipline areas. One way such 39 quality assurance might be achieved is to ensure graduates meet benchmarked standards in 40 the conceptual requirements of the discipline by comparing their learning outcomes with 41 those of with "single discipline" graduates from other comparable institutions. 42 • Fostering interdisciplinary exchanges: In order to encourage interdisciplinarity, it might 43 also be beneficial for the university to put in place mechanisms to recognise when 44 interdisciplinary exchanges occur naturally-that is, when discipline problems demand 45 them. These exchanges might be between students, staff and/or staff and students. Processes 46 to detect viable exchanges and ways to foster them would be helpful. In order to create and 47 31 maintain an environment where such exchanges might occur, processes also need to be put 1 in place to allow students to gain enough expertise to recognise the value and need of 2 interdisciplinary study and work. Formal "fieldwork" programs, on-site experience, 3 mentoring arrangements in real work situations, involvement in undergraduate workshops 4 and conferences, and similar mechanisms will be likely to assist in the creation of such an 5 environment. 6 • De-centring programs: In terms of preparing and supporting the on-going development of 7 staff for multidisciplinary and interdisciplinary environments, new academic development 8 programs may be necessary. These might focus on developing a "de-centring" of the 9 academic self of the participants and facilitating an appreciation of different world views. 10 This would, perhaps, promote critical 'conversations between disciplines, whilst retaining 11 the integrity of those disciplines' (Davidson, 2004, p. 302). One possible effect of such a 12 program would be to encourage interdisciplinary teaching and learning across the 13 curriculum. This should occur in a manner that does not violate disciplinary culture and 14 values, and instead promotes dialogue between protagonists from different disciplines. 15 • Evaluating interdisciplinarity: The evaluation of interdisciplinary teaching and learning also 16 needs careful thought. Recommended ways of undertaking this are outlined in detail 17 elsewhere (Field & Lee, 1992b). It has been noted that quantitative assessment measures are 18 least valuable where the outcomes cannot be easily specified (as in the case with 19 interdisciplinary studies). Qualitative measures which focus on student maturational 20 development involving portfolio analysis, for example, have been useful in some contexts in 21 determining the development of appropriate skills (Field & Lee, 1992b). Measures need to 22 be discussed and agreed upon within an institutional context and the systems used must feed 23 into both recognition and reward, and quality assurance programs in the particular 24 universities in which this interdisciplinary activity is occurring. Appropriate evaluation and 25 quality assurance processes in place would allow interdisciplinary exchanges to flourish 26 within an appropriate regulatory framework while ensuring that the learning aims in 27 academic disciplines are not compromised. 28 6. Conclusion 29 Any move by universities toward the incorporation of interdisciplinarity education involves a 30 number of complex considerations. Such a move is likely to bring several advantages to student 31 learning, and added institutional advantages to the enterprise of teaching and learning in higher 32 education. These advantages are not typically found in traditional approaches to higher education 33 through a focus on the discrete study of the disciplines. However, interdisciplinary higher education 34 is also likely to bring considerable challenges, including the unique epistemological and 35 pedagogical issues outlined in this chapter. It is hoped that the points raised in this chapter will 36 promote and contribute to discussion to further advance interdisciplinary higher education into the 37 future. 38 Acknowledgements: This paper amalgamates various points from the conference paper: "Interdisciplinary Higher 39 Education and the Melbourne Model" (Davies & Devlin, 2007a).
