Debugging on GeoGebra-based Computational Thinking+Mathematics lessons

Abstract

<p> Computational thinking (CT) has become a buzzword recently and gained more attention from countries and researchers. Researchers realize the importance of CT and integrate it into school subjects such as mathematics, science, language, and others. Our research tries to contribute to the plugged CT activities under mathematics subjects. Collaborating with mathematics teachers, principals, and a teacher trainer, we developed a sequence of lessons in GeoGebra. Our lessons integrate CT s facets in the topic of the area of a circle. The development of the GeoGebra-based Mathematics-CT lessons incorporated educational design research methodology. We improved our lessons and implemented them for a few students. In this paper, we focused only on the debugging skill being supported by GeoGebra. Our findings show that fixing commands can be challenging as students have been through several debugging, and it can be complicated if the errors are many. This paper shows the power of GeoGebra to learn integrated CT in mathematics lessons through creating objects and debugging the program.</p>
