Abstract

This classroom action research aimed to improve second-grade students’ learning outcomes on composing and decomposing plane figures through Project Based Learning (PjBL) based on puzzle creation activities. The research was conducted at SDN Balong, Blora Regency, involving 17 students consisting of 8 boys and 9 girls. The study applied the Kemmis and McTaggart classroom action research model carried out in two cycles: planning, action, observation, and reflection. Data were collected through observation, interviews, documentation, and evaluation tests. The findings showed that puzzle-based PjBL improved students’ mathematics learning outcomes. Learning mastery increased from 35.29% in the pre-cycle to 76.47% in cycle I and reached 82.35% in cycle II. The average score also improved from 60 in the pre-cycle to 70 in cycle I and 80,5 in cycle II. Puzzle projects encouraged students to participate actively and understand plane figure concepts more concretely. Therefore, puzzle creation-based PjBL can be used as an effective and enjoyable alternative for elementary mathematics learning. Future research is expected to develop puzzle-based (PjBL) in other mathematics materials.
