Examined how task design influences the effectiveness of peer collaboration in facilitating students' conceptual change in physics. Subjects were 8- to 12-year olds studying heating and cooling. Results showed the general superiority of collaborative tasks that both facilitate critical testing and require rules; task designs deploying one feature…

Suggests that young pupils find collaborative learning hard to sustain, and discusses interpretations of this observation. Suggests that theory and research have neglected situational continuities between formal and (more successful) informal collaborations. Argues for attending more carefully to the environments of joint problem solving and how…

Found that on average students gained in transformational reasoning but not in geometric description; however, the opposite was true for one quarter.
