PENGARUH MODEL PEMBELAJARAN PROBLEM BASED LEARNING BERBANTUAN MIND MAPPING TERHADAP HASIL BELAJAR IPAS SISWA KELAS 3 SD NEGERI 2 NYALIAN KLUNGKUNG TAHUN PELAJARAN 2025

Abstrak

Pembelajaran IPAS di sekolah dasar memerlukan model pembelajaran yang mampu meningkatkan pemahaman konsep dan keterampilan berpikir siswa secara optimal. Salah satu upaya yang dapat dilakukan adalah dengan menerapkan model pembelajaran Problem Based Learning berbantuan Mind Mapping. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Problem Based Learning berbantuan Mind Mapping terhadap hasil belajar IPAS siswa kelas III SD N 2 Nyalian Klungkung. Penelitian ini menggunakan jenis penelitian eksperimen semu (quasi experiment) dengan desain kelompok kontrol. Populasi dalam penelitian ini adalah seluruh siswa kelas III SD N 2 Nyalian yang berjumlah 28 siswa. Teknik pengambilan sampel yang digunakan adalah teknik sampel jenuh, yaitu dengan melibatkan seluruh populasi sebagai sampel penelitian. Pengumpulan data dilakukan melalui metode tes untuk mengukur hasil belajar IPAS siswa. Instrumen penelitian terlebih dahulu diuji validitas, reliabilitas, serta tingkat kesukaran butir soal dengan bantuan program Microsoft Excel dan SPSS Statistics 23. Data yang diperoleh dianalisis menggunakan uji Independent Sample t-Test. Hasil analisis menunjukkan nilai Sig. (2-tailed) sebesar 0,002 < 0,05, yang berarti terdapat perbedaan yang signifikan antara hasil belajar IPAS siswa yang dibelajarkan menggunakan model Problem Based Learning berbantuan Mind Mapping dengan siswa yang dibelajarkan menggunakan model pembelajaran konvensional. Berdasarkan hasil penelitian tersebut, dapat disimpulkan bahwa model pembelajaran Problem Based Learning berbantuan Mind Mapping berpengaruh positif dan signifikan terhadap hasil belajar IPAS siswa kelas III SD N 2 Nyalian Klungkung.

Science learning in elementary schools requires a learning model that can optimally enhance students' conceptual understanding and thinking skills. One effort that can be made is by implementing the Problem Based Learning model assisted by Mind Mapping. This study aims to determine the effect of the Problem Based Learning model assisted by Mind Mapping on the science learning outcomes of third-grade students at SD N 2 Nyalian Klungkung. This study employed a quasi-experimental research design with a control group. The population of this study consisted of all third-grade students at SD N 2 Nyalian, totaling 28 students. The sampling technique used was saturated sampling, which involved the entire population as the research sample. Data collection was conducted through a test method to measure students' science learning outcomes. The research instrument was first tested for validity, reliability, and item difficulty level using Microsoft Excel and SPSS Statistics 23. The obtained data were analyzed using the Independent Sample t-Test. The analysis results showed a Sig. (2-tailed) value of 0.002 < 0.05, which means there was a significant difference between the science learning outcomes of students taught using the Problem Based Learning model assisted by Mind Mapping and students taught using the conventional learning model. Based on these research findings, it can be concluded that the Problem Based Learning model assisted by Mind Mapping has a positive and significant effect on the science learning outcomes of third-grade students at SD N 2 Nyalian Klungkung.
