Argument mapping is a way of diagramming the logical structure of an argument to explicitly and concisely represent reasoning. The use of argument mapping in critical thinking instruction has increased dramatically in recent decades. This paper overviews the innovation and provides a procedural approach for new teaches wanting to use argument mapping in the classroom. A brief history of argument mapping is provided at the end of this paper.

The importance of teaching critical thinking skills at the college level cannot be overemphasized. Teaching a subcategory of these skills—argument analysis—we believe is especially important for first-year students with their college careers, as well as their lives, ahead of them. The struggle, however, is how to effectively teach argument analysis skills that will serve students in a broad range of disciplines.

Motivated by the call for more research on students’ perceptions of their ethical development in business education programs, this study examines students’ reflections on how their understanding of ethics was challenged and/or changed, and what facilitated the development of ethical decision-making approaches in a first-year accounting course. The results indicate that students developed more sophisticated and contextualised views of ethical issues in business, government and social contexts including the need to consider their impact on various stakeholders. Students attributed this development (...) to the various elements in the integrated course design including the real cases sourced in current newspaper articles, an ethical decision-making framework with various ethical perspectives, the reflective journal component and the ability to work in groups. These findings have implications for the design of effective ethics education programs in business. (shrink)

In this thesis, we introduce “Argueware”. This is a concept for an instructional group awareness tool which aims at supporting social interactions in co-located computer-supported collaborative argumentation settings. Argueware is designed to support the social interactions in the content and in the relational space of co-located collaborative argumentation. The support for social interactions in the content space of collaboration is facilitated with the use of collaborative scripts for argumentation as well with the use of an argument mapping tool. The support (...) for social interactions in the relational space of collaboration is facilitated with the use of different awareness mechanisms from the CSCL and the CSCW research fields. In this thesis, we examined how different awareness mechanisms facilitate the regulation of collaborative processes in the relational space of collaborative argumentation. Moreover, we studied how they affect the perceived team effectiveness and group performance in the content space of collaboration. Thereby, we studied also the effects of the design of the awareness mechanisms on the application of the mechanisms and the user experience with them. In line with the design-based research paradigm, we attempted to simultaneously improve and study the effect of Argueware on collaborative argumentation. Through a series of design-based research studies we tested and refined the prototypes of the instructional group awareness tool. Moreover, we studied the ecological validity of dominant awareness and instructional theories in the context of co-located computer-supported collaborative argumentation. The underlying premise of the Argueware tool is that a combination of awareness and instructional support will result in increased awareness of collaboration, which will, in turn, mediate the regulation of collaborative processes. Moreover, we assume that successful regulation of collaboration will result in high perceived team effectiveness and the group performance in turn. In the first phase of development of the Argueware tool, we built support of the content space of collaborative argumentation with argument scaffold elements in a pedagogical face-to-face macro-script and an argument mapping tool. Furthermore, we extended the use of the script for supporting the relational space of collaboration by embedding awareness prompts for reflecting on collaboration during regular breaks in the script. Following, we designed two variations of the same pedagogical face-to-face macro-script which differ with respect to the type of group awareness prompts they used for supporting the relational space of collaboration i.e. behavioral and social. Upon designing the two script variations, we conducted a longitudinal, multiple-case study with ten groups of Media Informatics master students where each group was conceptualized as a case. Students collaborated every time for arguing to solve one different ill-structured problem and for transferring their arguments in the argument mapping tool Rationale. Thereby, we intended to investigate the effects of different awareness prompts on collaborative metacognitive processes i.e., regulation, reflection, and evaluation the relation between collaborative metacognitive processes and the quality of collaborative argumentation as well as the impact of the two script variations on perceived team effectiveness and what was experience with the different parts of the script variations in the two groups and how this fits into the design framework by Buder. The quantitative analysis of argument outcomes from the groups yield no significant difference between the groups that worked with the BAS and the SAS variations. No significant difference between the script variations with respect to the results from the team effectiveness questionnaires was found either. Prompts for regulating collaboration processes were found to be the most successfully and consistently applied ones, especially in the most successful cases from both script variations and have influenced the argumentation outcomes. The awareness prompts afforded an explicit feedback display format through discussion. The prompted explicit feedback display format was criticized for running only on subjective awareness information on participation, contribution efforts and performance in the role. This resulted in evaluation apprehension phenomena and evaluation bias. The awareness prompts for reflection and evaluation did reveal frictions in the plan making process in the least successful groups. Problems with group dynamics but were not powerful enough to trigger the desired changes in the behaviors of the students. The prompts for evaluating the collaboration in both script variations had no apparent connection to argumentation outcomes. The results indicated that dominant presence phenomena inhibited substantive argumentation in the least successful groups. They also indicated that the role-assignment influenced the group dynamics by helping student’s making clear the labor division in the group. In the second phase of development of the Argueware tool, the focus is on structuring and regulating social interactions in the relational space of collaborative argumentation by means of scripted roles and role-based awareness scaffolds. We designed support for mirroring participation in the role and support for monitoring participation, coordination and collaboration efforts in the role. Moreover, we designed additional support for guiding participation in the role i.e., role-based reminders as notifications on smartwatches. In a between-subjects study, ten groups of three university students each worked with two variants of the Argueware for arguing to solve one ill-structured problem and transferring their arguments in the argument mapping tool Rationale. Next, to that, students should monitor their progress in their role with the role-based awareness visualization and the self-assessment questionnaire with the basic awareness support and the enhanced awareness support. Half of the groups worked only with the role-based awareness visualization and the self-assessment questionnaire while the other half groups received additional text-based awareness notifications via smartwatches that were sent to students privately. Thereby, we tested the use of different degrees of awareness support in the two conditions with respect to their impact on a) self-perceived awareness of performance in the role and of collaboration and coordination efforts, b) on perceive team effectiveness, c) group performance. We hypothesized that students in EAC will perform better thanks to the additional awareness reminders that increased the directivity and influenced their awareness in the role. The mixed methods analysis revealed that the awareness reminders, when perceived on time, succeeded in guiding collaboration. Students in the EAC condition improved their awareness over time. These results indicated that enhanced awareness support in the form of additional guidance through awareness reminders can boost the awareness of students’ performance in the role as well as the awareness of their coordination and collaboration efforts over time by directing them back to the mirroring and monitoring tools. Moreover, students in EAC exhibited higher perceived team effectiveness than the students in BAC. However, no significant differences in building of shared mental models or performing in mutual performance monitoring were found between the groups. However, students in BAC and EAC did not differ significantly with respect to the formal correctness or evidence sufficiency of their group argumentation outcomes. Moreover, technical difficulties with the smartphones used as delivery devices for the awareness reminders hindered the timely perception of the reminders and thus their effect on participation. Finally, the questionnaire on the experience with the different parts of Argueware system indicated the need for exploring further media for supporting the awareness reminders to avoid the overwhelming effects of the multiple displays of the system and enhancing higher perceptiveness of the reminders with low interruption costs for other group members. The rather high satisfaction with the use of the role-based awareness visualization and the positive comments on the motivating aspects of monitoring how the personal success contributes to the group performance indicate that the group mirror succeeded in making group norms visible to group members in a non-obtrusive way. The high interpersonal comparability of performances without moderating the group ‘s interaction directly in the basic awareness condition was proven to be the favored design approach compared to the combination of group mirror and awareness reminders in the enhance awareness condition. In the third phase of development of Argueware, we focused on designing and testing different notification modes on different ubiquitous mobile devices for facilitating the next prototype of a notification system for role-based awareness reminders. Thereby, the aim of the system was again to guide students’ active participation in collaborative argumentation. More specifically, we focused on raising students’ attention to the reminders and triggering a prompter reaction to the contents of the reminders whilst avoiding a high interruption cost for the primary task in the group. These goals were translated into design challenges for the design of the role-based awareness notification system. The system should afford low interruptions, high reaction and high comprehension of notifications. Notification systems with this particular configuration of IRC values are known as "secondary display" systems. Next, we designed three low-fidelity prototypes for a role-based notification system for delivering awareness reminders: The first ran on a smartwatch and afforded text-based information with vibration and light notification modalities. The second ran on smartphone and afforded text-based information with vibrotactile and light-based notification modalities. Finally, the third prototype run on a smart-ring which afforded graphical- based information with and light and vibration notification modalities. To test the suitability of these prototypes for acting as “secondary display” systems, we conducted a within-subjects user study where three university students argued for solving three different problem cases and producing an argument map in each of the three consecutive meetings in the Argueware instructional system. Students were assigned the roles of writer, corrector and devil`s advocate and were instructed to maintain the same role across the three meetings. In each meeting, students worked with a different role-based awareness notification prototype, where they received a notification indicating their balloon is not growing bigger after five minutes of not exhibiting any role-specific behaviors. The role-based awareness notification prototypes aimed at introducing timely interventions which would prompt students to check on their own progress in the role and the group progress as visualized by the role-based awareness visualization on the large display. Ultimately, this should prompt them to reflect on the awareness information from the visualization and adapt their behaviors to the desired behavior standards over time. Results showed that students perceived the notifications from all media mostly based on vibration cues. Thereby, the vibration cues on the wrist were considered the least disruptive to the main task compared to the vibration cues on finger and the vibration cues on the desk. Students also declared that vibration cues on wrist prompted the fastest reaction i.e., attending to notification by interacting with the smartwatch. These results indicate that vibration cues on the wrist can be a suitable notification mechanism for increasing the perceived urgency of the message and prompting the reaction on it without causing great distraction to the main task, as studies previous studies showed before. Based on very limited qualitative data on light as notification modality and awareness representation type no inferences could be made about its influence on the cost of interruption, reaction and comprehension parameters comprehensiveness. The qualitative and quantitative data on the experience with different media as awareness notification systems indicate that smartwatches may be the most suitable medium for acting as awareness notification medium with a “secondary display” IRC configuration. However, this inference needs to be tested in terms of a follow up study. In the next study, the great limitations of study need to be repaired. Finally, the focus should be on comparing notification modalities of one medium based on a larger set of participants and with the use of objective measurements for the IRC parameter values. Finally, we draw conclusions based on the findings from the three studies with respect to the role of awareness mechanisms for facilitating collaborative processes and outcomes and provide replicable and generalizable design principles. These principles are formed as heuristic statements and are subject to refinement by further research. We conclude with the limitations of the study and ideas for future work with Argueware. (shrink)
