Abstract

Mathematics learning requires instructional approaches that promote students' active participation and meaningful conceptual understanding. However, many junior secondary school students experience difficulties in learning equivalent fractions because the concepts are abstract and classroom instruction is often dominated by teacher-centered approaches with limited use of interactive learning media. This study aimed to examine the effect of the Discovery Learning model assisted by PhET Interactive Simulations on students' mathematics learning outcomes in equivalent fraction material. The study employed a quantitative approach using a quasi-experimental pretest–posttest control group design. Sixty seventh-grade students from SMP Negeri 2 Padangsidimpuan participated in the study and were divided into an experimental group and a control group. Data were collected using a validated mathematics achievement test and analyzed through descriptive statistics, the Kolmogorov–Smirnov normality test, Levene's homogeneity test, an Independent Samples t-test, N-Gain analysis, and the coefficient of determination using IBM SPSS Statistics. The results revealed that students who learned through Discovery Learning assisted by PhET Interactive Simulations achieved significantly higher mathematics learning outcomes than those who received conventional classroom instruction (p < 0.05). The experimental group also demonstrated greater learning improvement, as indicated by a higher N-Gain score, while the instructional treatment contributed 39.3% of the variance in students' learning outcomes. These findings indicate that integrating Discovery Learning with PhET Interactive Simulations provides an effective student-centered learning environment that enhances conceptual understanding and improves mathematics learning outcomes. Therefore, this instructional approach can be recommended as an alternative strategy for teaching equivalent fractions at the junior secondary school level.

Abstract

Sumber belajar adalah segala sumber yang dimanfaatkan guru dalam proses pembelajaran baik secara terpisah maupun terkombinasi untuk tercapainya tujuan pembelajaran. Perangkat pembelajaran yang dibutuhkan oleh guru salah satunya yaitu modul ajar. Modul ajar merupakan kata lain RPP pada kurikulum merdeka. Profil pelajar rahmatan lil alamin komponen yang mesti dimiliki modul ajar. Profil pelajar rahmatan lil alamin dapat mewujudkan perilaku taffaquh fiddin peserta didik. Tenaga pendidik diharuskan menguasai penggunaan perangkat teknologi dalam penerapan modul ajar. Tujuan penelitian ini yaitu untuk mengahasilkan modul ajar yang valid. Jenis penelitian yang digunakan yaitu model pengembangan 4-D yaitu Define (Pendefenisian), Design (Perancangan), Develop (Pengembangan), and Dessiminate (Penyebaran). Tetapi, penelitian ini dibatasi sampai tahap pengembangan. Penelitian ini dilaksanakan di UIN Syekh Ali Hasan Ahmad Addary Padangsidimpuan dan SMA Negeri 1 Angkola Selatan. Validator modul ajar ini yaitu 3 validator yaitu dosen jurusan tadris biologi UIN SYAHADA. Penelitian ini menghasilkan modul ajar berbasis technological pedagogical and content knowledge yang valid dengan rata-rata nilai validitas 91,48%.
