Abstract

The aim of the study is to develop an instructional method to improve the representational functions and students’ abilities of thinking and expressing in science classes. Childrens’ representation in science learning includes some modes and levels (enactive, iconic and symbolic). To improve the abilities of thinking and expressing, children need to make connections between these modes of representation. In this study, firstly, we propose a new representational network model considering the level of dimensions which are able to visualize the childrens’ thinking processes involved in solving a problem. Secondly, we develop an instructional method to attain a high-order level of operating representation.<BR>The result is that children are able to think and express autonomously through teachers’ providing strategies for promoting meaningful encoding, that is, imagery, organization, schema activation and elaboration accordingly. Children’s critical thinking skills, decision-making and expression are developed simultaneously.
