Abstract
The purpose of this study was to improve learning outcomes of mathematics on the subject of congruence and similarity in class IX H MTsN 2 Ponorogo in the academic year 2021/2022. This research method is best practice research. The research subjects were students of MTsN 2 Ponorogo class IX H in the 2021/2022 academic year. The learning approach used is Problem Based Learning, with the learning model used is "PREMOGAWA" namely cooperative learning model Gallery Walk Presentation Model. The results of the UH 1 analysis where learning is still conventional, the highest score is 80, the lowest value is 25. The average value is 62.36. The number of students who completed learning 15 (46.88%), and the number of students who did not complete 17 (53.13%). While the results of UH 2 where learning uses PREMOGAWA (Gallery Walk Presentation Model) the highest score is 100, the lowest value is 75. The average value is 81.90. Many students finished studying 31 (96.88%) and many students did not complete learning 1 (3.13%)
ABSTRAKTujuan penelitian ini adalah untuk meningkatkan hasil belajar matematika tentang materi Kekongruenan dan Kesebangunan pada siswa kelas IX H MTsN 2 Ponorogo Tahun pelajaran 2021/2022. Metode penelitian ini adalah penelitian best practice. Subyek penelitian adalah siswa MTsN 2 Ponorogo kelas IX H Tahun pelajaran 2021/2022. Pendekatan pembelajaran yang digunakan adalah Pembelajaran Berbasis Masalah (Problem Based Learning), dengan model pembelajaran yang digunakan adalah “PREMOGAWA” yaitu model pembelajaran kooperatif Presentasi Model Galeri Walk.
