In the first stage, students’ complete questions consisting of 3 items, while researchers observe student learning activities while writing important notes to be confirmed at the interview. In the second stage, task-based interviews to explore and clarify the types of representations made by students and capture data that has not been obtained through test results. The data that has been obtained are analyzed by the stages of transcribing data, reducing data, categorizing data, drawing thinking structures, and making conclusions.
