Abstract

Pengembangan dan pelaksanaan pembelajaran ini bertujuan untuk mengetahui dan mendeskripsikan model pembelajaran Problem based learning (PBL) pada mata pelajaran matematika di sekolah dasar yaitu dengan meninjau pencapaian tujuan pembelajaran. Prosedur pelaksanaan awal pembelajaran mengembangkan dimensi profil pelajar pancasila terintegrasi IT, kegiatan inti pembelajaran melibatkan budaya-kearifan lokal setempat mengikuti sintaks PBL terpadu dengan strategi TPACK serta diskusi kelompok heterogen berdasarkan gender dan asasmen awal, sedangkan kegiatan akhir memuat prosesi penutup pembelajaran lengkap dengan evaluasi sumatif-formatif pada ranah kognitif, afektif, dan psikomotor. Pembelajaran ini dilaksanakan di SD Negeri Cirewed Kabupaten Tangerang Banten pada Rabu 16 Oktober 2024. Hasil tes sumatif menunjukkan perolehan rata-rata nilai matematika dari 24 peserta didik di kelas IV sebesar 91, perolehan tersebut berada di atas KKTP yang telah ditetapkan yaitu 70. Hal lain ditunjukkan oleh tercapainya dimensi profil pelajar pancasila pada aspek afektif dan psikomotor. Hasil asesmen formatif pada ranah afektif dan psikomotor menunjukan perolehan nilai tinggi yang memberi penjelasan bahwa tujuan pembelajaran aspek afektif-psikomotor tercapai dalam proses pembelajaran.

Abstract

This research is motivated by the importance of scientific literacy at the elementary school level and the need for an effective learning model to improve it, by considering students' psychological factors such as learning motivation. Objective: This study aims to investigate the effect of Problem-Based Learning (PBL) and learning motivation on elementary school students' scientific literacy, and to test the interaction between the two variables. Method: This study used a quasi-experimental design with a pretest–posttest nonequivalent control group. The sample consisted of 60 fourth-grade students at Mekar Bakti Public Elementary School, Indonesia, divided into two classes (n=30 each). Scientific literacy was measured using a PISA-oriented essay test (scale 0–100), while learning motivation was assessed with a 40-item Likert questionnaire (α=0.884). Data were analyzed using a 2×2 factorial ANOVA and Tukey HSD follow-up test. The findings showed that: Students in the PBL class achieved higher scientific literacy than those in the conventional class (M=78.63 vs 68.57; p=0.001); Students with high motivation outperformed students with low motivation (M=76.67 vs 70.53; p=0.039); There was a significant interaction between PBL and learning motivation (F (1.56) =17.23; p<0.001); The post-hoc test results showed that the PBL-high motivation group performed significantly better than the other three groups. These findings indicate that the PBL model is most effective when student motivation is high.
