Development and application of programming education model based on visual thinking strategy for pre-service teachers

Abstract

In the software-oriented society, the importance of computational thinking for problem solving is increasing day by day. In particular, programming is a good way to improve this kind of computational thinking, and beginners are having difficulties in creating and programming procedures for problem solving. In this study, we developed a Thinking-Revise-Encoding-Evaluating (TREE) model based on a visual thinking strategy for pre-service teachers and applied a 15-week curriculum. The results of the study showed that pre-service teachers' SW education perception, block programming ability, computational thinking, and satisfaction were significant.
