Abstract

The development of innovative learning models in education encourages the use of approaches capable of enhancing students' active engagement and problem-solving skills. Fraction comparison material is abstract in nature, thus requiring learning models and media that can help students visualize concepts concretely and contextually through Problem Based Learning assisted by Puzzle media. This study aims to determine the effectiveness of implementing the Problem Based Learning (PBL) model assisted by Puzzle media on students' mathematical problem-solving abilities in fraction comparison material. The study was conducted at one of the public elementary schools in Purwakarta with 25 fifth-grade students of class V-A as subjects, using a Pre-experimental One Group Pretest-Posttest Design. Data were collected through written essay tests consisting of 5 questions administered as pretest and posttest to measure students' ability to analyze (C4) and create (C6). The treatment applied the PBL model through five stages: orienting students to the problem, organizing students for learning, guiding investigation, developing and presenting work, and evaluating the problem-solving process, integrated with Puzzle media as a concrete learning tool. The results showed an increase in the average score from 51.68 on the pretest to 76.96 on the posttest with a difference of 25.28. The Shapiro-Wilk normality test indicated that the posttest data was not normally distributed, leading to the non-parametric Wilcoxon Signed Rank Test. The Wilcoxon test results showed that all 25 students had higher posttest scores than pretest scores (Positive Ranks = 25, Negative Ranks = 0, Ties = 0), with Z = -4.378 and significance p < 0.001, indicating a significant difference between pre- and post-treatment results. The average N-Gain Score of 0.4830 falls in the moderate category, indicating that the Problem Based Learning model assisted by Puzzle media is effective in improving students' mathematical problem-solving abilities in fraction comparison material at the elementary school level.

Abstract

Masalah utama yang melatarbelakangi penelitian ini adalah rendahnya pemahaman siswa akibat pembelajaran yang masih berpusat pada guru dan kurang melibatkan aktivitas eksplorasi serta media pembelajaran yang konkret. Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model Discovery Learning berbantuan media Diorama Card dengan pendekatan Teaching at the Right Level (TaRL) terhadap pemahaman sains siswa sekolah dasar, khususnya pada materi metamorfosis hewan. Penelitian ini menggunakan metode eksperimen dengan desain Pre-Experimental One Group Pretest-Posttest Design yang dilaksanakan pada siswa kelas III SD Negeri Purwakarta dengan jumlah subjek 23 siswa. Instrumen pengumpulan data berupa tes hasil belajar yang terdiri dari 5 soal pretest dan 5 soal posttest. Peningkatan pemahaman siswa dianalisis menggunakan uji-t berpasangan (paired sample t-test). Hasil penelitian menunjukkan bahwa nilai rata-rata uji-t berpasangan (paired sample t-test) yang diperoleh adalah 0.323, yang termasuk kategori sedang. Temuan ini mengindikasikan bahwa penerapan Discovery Learning berbantuan Diorama Card dengan pendekatan TaRL memberikan pengaruh positif dan efektif secara moderat dalam meningkatkan pemahaman sains siswa. Meskipun terdapat variasi peningkatan antar siswa, pembelajaran yang diterapkan terbukti mampu membantu siswa memahami konsep metamorfosis hewan melalui proses penemuan, visualisasi konkret, serta pengelompokan sesuai tingkat kemampuan. Dengan demikian, model pembelajaran ini dapat dijadikan alternatif strategi pembelajaran IPA di sekolah dasar untuk meningkatkan pemahaman konsep secara lebih bermakna.
