Multiple representation in learning about evaporation

This study draws on recent research on the central role of representation in learning. While there has been considerable research on Children’s understanding of evaporation, the representational issues entailed in this understanding have not been investigated in depth. The study explored students’ engagement with science concepts relating to evaporation through various representational modes such as diagrams, verbal accounts, gestures, and captioned drawings. This engagement entails students a) clarifying their thinking through exploring representational resources, b) developing understanding of what these representations signify and c) learning how to construct and interpret the representational aspects of scientific explanation. The study indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science. Primary school classroom sequences and structured interviews with 12 children indicated a range of learning potentialities flowing from this focus. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both a) richer conceptual understanding by students and b) enhanced teacher insights into students’ thinking.
