Exploring students’ mathematical thinking skills in educational robotics activities

Abstract

This study aims to determine how mathematical thinking skills are exhibited in educational robotics activities. In the study, activities with Lego Mindstorms EV3 robot kits were designed and implemented. An exploratory case study is adopted with secondary school students. The data obtained from open-ended questions, observations, and interviews were analyzed by content analysis. The results demonstrated various strategies in specializations and generalizations in terms of mathematical thinking skills while solving robotics problems. In this framework, "noticing symmetry", "finding a relationship between angle and direction of rotation", "noticing obtuse angles, acute angles”, and “noticing the change of sign when changing the direction of angles” were found prominent strategies in the specialization dimension. The strategies of "finding solutions compatible with the problem", "using algebraic operations", and "making calculations" were found prominent in the generalization. We hope that the findings of this study will assist in the future design and implementation of the applications of educational robotics activities for mathematical thinking.
