Purpose: The aim of this research was to test whether Hong Kong science students would prefer a learning environment based on critical constructivism and whether a closer preferred-actual fit to such an environment would be associated with better learning outcomes. Method: The participants were 149 Hong Kong secondary school Chemistry students aged 16--19 years. They completed actual and preferred forms of a Chinese version of the Constructivist Learning Environment Survey and measures of self-efficacy and intrinsic value of their Chemistry course. (...) Their Chemistry examination scores were also obtained at the end of the course. Findings: Analysis showed that these students would prefer their Chemistry classrooms to be more personally relevant, to allow students more say and to share more control, and to encourage more negotiation with their teacher. Regression surface analysis showed that congruence of person environment fit did not influence examination results but was associated with greater valuing of the course and higher student self-efficacy. Research implications: Further research with a wider sampling from Hong Kong and elsewhere and focusing on other subject areas will be necessary to assess the generalizability of these findings. Practical implications: It seems that educational reforms based on critical constructivist principles may be of value in non-Western contexts. Original value: Educational reforms in Hong Kong and elsewhere currently are based on traditional constructivist principles. But this is the first research to support a more radical approach in what is usually regarded as a relatively conservative Asian educational context. (shrink)

One of the most serious pre-occupations of post-medieval philosophy has been to distinguish those kinds of assertion which are either true or false from those which are neither true nor false. A solution to this problem would be of the highest importance. It would indicate in what areas rational inquiry has some hope of success and in what areas it is doomed to frustration. It would tell us, for example, whether it is worth trying to think about the possible mistakenness (...) of our moral principles, or whether such thinking is bound to be ineffective since no truth or falsity attaches to them.

In his book The Retreat to Commitment Professor Bartley raised an important problem: can rationalism can rationalism be held in a rational way, that is, in a way that complies with its own requirements? Or is there bound to be something irrational in the rationalist's position? Briefly, Hartley's answer was that an element of irrationalism is involved in extant versions of rationalism; however, Bartley proposed a new version of rationalism that can, he claimed, be held in a way that is (...) rational according to its own account of rationality. Bartley called this ‘Comprehensively Critical Rationalism’. (shrink)

This book contains important technical innovations, including comparative measures for the testable content, depth, and unity of scientific theories. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich (...) scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Object of this reply. A chap like myself, who struggles along with an amateur's box of logical tools, is bound to feel uneasy when his arguments are probed by the kind of logical precision-instruments which Professor Hempel manipulates so effortlessly. Yet after painstakingly working over his technical arguments, and after appealing for expert assistance on matters outside my competence,1 I have reached the surprising and agreeable conclusion that my argument stands intact and that Professor Hempel's criticisms reveal once more the (...) hopelessness of the position he defends—or rather, of the position he now defends.
