Efforts to Improve Mathematics Learning Outcomes in Flat Shape Materials through Puzzle Media

Abstract

This classroom action research aimed to improve the mathematics learning outcomes of 17 second-grade students at MI Nurul Huda, Depok, by implementing puzzle media. The study comprised three cycles, each consisting of four stages. Data were gathered through tests, interviews, and observations. Pre-cycle assessment showed a low average score of 54.11 with a 24% mastery rate (4 students completed, 13 students incomplete). After the first cycle, the average score increased to 68.23, with a 53% mastery rate (9 students completed, 8 students incomplete). The second cycle further raised the average score to 79.70, with an 82% mastery rate (14 students completed, 3 students incomplete). In the third cycle, the average score reached 86.76, with a 94% mastery rate (16 students completed, 1 student incomplete). Interviews revealed that students found learning through puzzle media enjoyable. The findings highlight the effectiveness of puzzle media in improving mathematics learning outcomes, particularly for flat-shaped materials.
