Solving Circle Material Problems with the Help of Van Hiele's Bridge Theory for Sixth Class Students of Madrasah Ibtidaiyah “Miftahul Ulum” Mranggen, Demak, Indonesia

Abstract

The aim of this research is to improve the learning activities of class VI students of Madrasah Ibtidaiyah "Miftahul Ulum" Mranggen-Demak Indonesia through the application of the van Hiele Bridge in the discussion of circular flat planes. The research used is descriptive qualitative. Geometry material, a learning theory that is suitable for teaching geometry material is van Hiele's theory. Van Hiele's theory with five levels of students' geometric thinking, namely level 0 (visualization), level 1 (analysis), level 2 (informal deduction), level 3 (deduction), and level 4 (rigor), and is supported by five phases: (1) information phase; (2) directional orientation; (3) explanation; (4) free orientation; and (5) integration. Problem solving learning model with the van Hiele bridge as a guide to the learning steps of van Hiele theory with the model teacher playing the role of accompanying students in solving problems. The results of the research show that student activity in learning has increased, namely that students actively ask questions about the solutions they are working on, or whether the problem is unclear. Conclusion: Students feel meaningful in participating in mathematics learning.
