Collaborative reasoning on self-generated analogies. Conceptual growth in understanding scientific phenomena

This study investigated fourth graders’ self‐generated analogies, that is, own analogies giving self‐explanations — opposed to analogies provided by a teacher — and the effects of their collaborative reasoning and arguing over these analogies on individual understanding of three scientific phenomena concerning air pressure. At the beginning the children were individually asked to give their own explanations, explicitly encouraged to think of something similar which could help them to understand better what they had experienced. Then, divided in small groups they were asked to compare their accounts to collabora‐tively reach a shared explanation of each phenomenon. At the end, the children were again individually asked to give their explanations. The data underwent both a qualitative and quantitative analysis. The first showed that the children, on the basis of their alternative representations of what air could do, produced and used their own analogies as self‐explanations both to learn the new material and communicate their understanding to others. Moreover, the analysis of the collaborative reasoning and arguing developed in small group discussions revealed that through steps of critical opposition and co‐construction, the learners negotiated and renegotiated meanings and ideas to share a new common knowledge based on the recognition of more appropriate analogies supporting more advanced explanations. The quantitative analysis showed that socio‐cognitive interaction in small groups was fruitful as the children significantly progressed on an individual plane in giving their own explanations of each phenomenon as well as in recognizing the similarities between the three phenomena. In addition, the qualitative data showed evidence that the children were able to express metacognitive awareness of their conceptual growth. Finally, educational implications have been drawn.
