GeoGebra applet to learn programming and debugging in mathematics lessons

This study presents the development of integrated computational thinking in mathematics lessons. The lessons were intended to support students' computational thinking while learning mathematics. To do so, we used the educational design research (EDR) methodology to develop the lessons. We collaborated with mathematics teachers and practitioners to improve the lessons. We also piloted the lessons for a few junior high school students in Indonesia. We collected data from online discussions with teachers and practitioners, GeoGebra files, and screen video recordings. We found that collaboration with teachers and practitioners helped us to refine the lessons. The pilot study showed the engagement of students in programming and debugging. Mostly students could solve the final task to create an inscribed polygon in a circle.
