Abstract

ABSTRAK Penelitian ini dilatarbelakangi oleh rendahnya pemahaman konsep IPAS peserta didik. Pemahaman konsep IPAS berguna dalam memahami tentang fenomena alam dan sosial di lingkungan sekitar peserta didik serta berguna dalam membentuk karakter baik peserta didik. Salah satu cara untuk mengoptimalkan pemahaman konsep peserta didik adalah melalui penggunaan model pembelajaran yang tepat. Penelitian ini menggunakan teori pembelajaran konstruktivisme dan model pembelajaran Project Based Learning. Tujuan penelitian ini adalah untuk mengetahui pengaruh model pembelajaran Project Based Learning berbantuan media audio visual terhadap pemahaman konsep IPAS di Kelas IV SDN 2 Sukarame Bandar Lampung. Metode penelitian yang digunakan dalam penelitian ini adalah pendekatan kuantitatif dengan jenis penelitian quasi eksperimental design tipe pretest-posttest control group design. Penelitian dilaksanakan pada dua kelas, yaitu kelas ekperimen berjumlah 27 peserta didik yang menggunakan model pembelajaran Project Based Learning berbantuan media audio visual dan kelas kontrol berjumlah 27 peserta didik yang menggunakan model pembelajaran Contextual Teaching Learning. Proses penelitian meliputi pretest, pemberian perlakuan, dan posttest untuk mengukur pemahaman konsep peserta didik sebelum dan sesudah perlakuan. Data hasil penelitian ini diuji hipotesis dengan menggunakan independent sampel t-test pada taraf signifikansi 5% menunjukkan nilai p-value sebesar 0,03<0,05 yang berarti H0 ditolak dan H1 diterima. Kemudian persentase nilai N-Gain kelas eksperimen diperoleh sebesar 57% lebih tinggi dibandingkan kelas kontrol yang menunjukkan bahwa pengaruh penggunaan model pembelajaran Project Based Learning berbantuan media audio visual cukup efektif terhadap pemahaman konsep IPAS. Kesimpulan penelitian ini adalah terdapat pengaruh model pembelajaran Project Based Learning berbantuan media audio visual terhadap pemahaman konsep IPAS di kelas IV SDN 2 Sukarame Bandar Lampung.

Understanding Natural and Social Science concepts is useful in understanding natural and social phenomena around students’ environment and is useful in forming good character. One way to optimize students' conceptual understanding is through the use of appropriate learning models. This research used constructivist learning theory and project based learning model. The purpose of this study was to determine the effect of the Project-Based Learning model assisted by audio-visual media on the understanding of Natural and Social Science concepts in class IV of SDN 2 Sukarame, Bandar Lampung. The research method used in this study was a quantitative approach with a quasi-experimental design, a pretest-posttest control group design. The study was conducted in two classes: an experimental class of 27 students using the Project-Based Learning model assisted by audio-visual media, and a control class of 27 students using the Contextual Teaching and Learning model. The research process included a pretest, treatment, and posttest to measure students' conceptual understanding before and after the treatment. The data from this study were tested for hypotheses using an independent sample t-test at a significance level of 5% showing a p value of 0.03 <0.05 which means H0 is rejected and H1 is accepted. Then the percentage of N-Gain score in the experimental class is 57% higher than the control class, which indicates that the influence of the use of the Project Based Learning learning model assisted by audio visual media is quite effective in understanding the concept of Natural and Social Sciences. The conclusion of this study is that there is an influence of the Project Based Learning model assisted by audio visual media on understanding of the concept of Natural and Social Sciences in class IV SDN 2 Sukarame Bandar Lampung. Keywords: Project Based Learning Model, Audio Visual Media, Conceptual understanding, Natural and Social Sciences
