Reasoning may be defined as a deliberate effort to coordinate inferences so as to reach justifiable conclusions. Thus defined, reasoning includes collaborative as well as individual forms of cognitive action. The purpose of the present study was to demonstrate a circumstance in which collaborative reasoning is qualitatively superior to individual reasoning. The selection task, a well known logical hypothesis-testing problem, was presented to 143 college undergraduates-32 individuals and 20 groups of 5 or 6 interacting peers. The correct (falsification) response pattern (...) was selected by only 9% of the individuals but by 75% of the groups. The superior performance of the groups was due to collaborative reasoning rather than to imitation or peer pressure. Groups typically co-constructed a structure of arguments qualitatively more sophisticated than that generated by most individuals. The results support Piagetian and Habermasian views of peer interaction as a locus of rational social processes. (shrink)

Based on an analysis of a fundamental distinction between metaphors of ’finding‘ versus ’making‘ for the obtaining of new knowledge, a number of constructivist positions in education are discussed and criticised, taking account of earlier criticism particularly by Suchting and by Matthews. Constructivist claims which are denied include the claim that we have no direct access to the world, and the claim that communication is inherently meaningless. What is valuable in constructivism, namely the insistence on active learning, on respect for (...) the pupil‘s own thinking, and on the high priority needed for ideas taught to make sense to pupils, together with the reminder that science is a human product, is important to retain without its additional and ill-founded philosophical baggage.

This chapter considers Wittgenstein’s philosophy, particularly as elaborated in Philosophical Investigations and later works, as it has obtained relevance in science education research. The specific focus is on contributions related to students’ learning of science. Wittgenstein’s writings have been used in science education in several ways: to argue for an alternate conception of rationality in theories of learning science, to support theories examining the discursive and social nature of learning, to advocate for investigations of science classrooms that parallel ethnographic and (...) sociological investigations of professional science labs, and to develop alternative research methodologies. An examination of this influence in science education necessitates discussion of the frequent implicit attempts made to reconcile Wittgenstein’s analytic philosophy with empirical habits firmly grounded in a cognitivist tradition. Particular attention is given to the way in which a typical focus in science education on students’ “meaning making” is likely at odds with Wittgensteinian philosophy. It is argued that the exemplars provided in his later work suggest that conceptual clarity is necessary for coherence in asking empirical questions and interpreting results and that they imply an alternative, descriptive orientation for researchers.
