PENGARUH PROBLEM-BASED LEARNING TERHADAP PEMAHAMAN KONSEP DAN PEMECAHAN MASALAH DALAM MATERI HUKUM ARCHIMEDES
<p align="center"><strong>Abstrak</strong></p><p>Penelitian bertujuan untuk menguji pengaruh model pembelajaran <em>problem</em><em>-based learning</em> terhadap pemahaman konsep dan pemecahan masalah materi hukum Archimedes di kelas XI IPA SMA Negeri 1 Ketungau Tengah. Penelitian menggunakan <em>quasi</em><em>-experimental designs </em>dengan <em>nonequivalent groups posttest only</em>. Instrumen yang digunakan adalah butir soal pemahaman konsep berbentuk tes pilihan ganda dan pemecahan masalah berbentuk tes uraian. Populasi penelitian seluruh siswa kelas XI IPA SMA Negeri 1 Ketungau Tengah tahun pelajaran 2018/2019. Sampel sebanyak 37 orang siswa yang terdiri dari dua kelas yang diambil dengan teknik <em>cl</em><em>uster random sampling</em>. Analisis data menggunakan uji MANOVA dua arah. Hasil penelitian: (1) Kemampuan pemahaman konsep siswa cukup dan pemecahan masalah siswa baik setelah diterapkannya model pembelajaran <em>problem</em><em>-based learning</em>; (2) Kemampuan pemahaman konsep siswa kurang dan pemecahan masalah siswa sangat kurang setelah diterapkannya model pembelajaran konvesional; dan (3) Terdapat pengaruh model pembelajaran <em>problem</em><em>-based learning </em>terhadap pemahaman konsep dan pemecahan masalah materi hukum archimedes.</p><p><strong><em><br /></em></strong></p><p><strong><em>Abstract</em></strong></p><p><em>The research aims to examine the effect of the problem-based learning model of learning on concept understanding and problem-solving of Archimedes material in class XI IPA of SMA Negeri 1 Ketungau Tengah. The research used quasi-experimental designs with nonequivalent groups posttest only. The instrument used was a matter of understanding the concept in the form of multiple-choice tests and problem-solving in the form of description tests. The population of the research was all students of class XI IPA of SMA Negeri 1 Ketungau Tengah in the academic year 2018/2019. A sample of 37 students consisted of two classes taken cluster random sampling technique. Data analysis using the MANOVA two-way test. The results of the research: (1) The ability to understand students' concepts is sufficient and students' problem-solving is good after the application of the problem-based learning model; (2) The ability to understand students' concepts is lacking and students' problem-solving is very lacking after the application of conventional learning models; and (3) There is an influence of the problem-based learning model on the understanding of concepts and problem-solving in Archimedes material.</em></p>
