This study compared students' learning in troubleshooting and problem solving activities. The troubleshooting activities provided students with solutions to conceptual problems in the form of refutation texts; namely, solutions that portray common misconceptions, refute them, and then present the accepted scientific ideas. They required students…

I examined the impact of a self-diagnosis activity on students' conceptual understanding and achievements in physics. This activity requires students to self-diagnose their solutions to problems that they have solved on their own--namely, to identify and explain their errors--and self-score them--that is, assign scores to their solutions--aided by…

This study is based on our belief that mathematics should be challenging in any classroom and that mathematical challenge is among the central factors that determine the quality of mathematics lessons. Choosing challenging mathematical problem for the students is central in teachers' work while their conception of mathematical challenge can…

Purpose--To illuminate the importance of the communal deliberative process, as a form of collective thinking, in overcoming the growing complexities of schoolwork in uncertain and turbulent environments. Design/methodology/approach-- Introduces the notion of deliberation as evolved from Dewey's moral theory, the essential phases and elements of…

Forty U.S. and 70 Israeli occupational therapy students received lecture or group discussion treatments in groups based on active versus reflective learning styles. Matching reflective style with lectures and active style with discussion resulted in better problem-solving performance and shorter learning time. (SK)
