In particular, the purpose of this activity was to apply a scientific approach through a problem-based instruction model in Mathematics with a lesson on Circle shape for grade 6 students. This activity was carried out in 3 stages, namely the preparation stage, starting with socialization and willingness collaboration from the elementary school, contacting the teacher to arrange a schedule of activities, and preparing for the implementation. The second stage was implementing activities, namely experimental methods, lectures, demonstrations, and small group discussions.
