Abstract

Model pembelajaran berpikir induktif adalah model pembelajaran berbasis memproses informasi, dengan model ini siswa dituntut aktif berlajar secara mandiri, menemukan konsep dan gagasan, serta mengembangkan kemampuan berpikir kritis yang pada akhirnya berpengaruh terhadap pemecahan masalah. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran berpikir induktif terhadap kemampuan pemecahan masalah matematis siswa SMK Swasta PAB Medan Estate. Penelitian ini dilaksanakan di bulan Maret-Mei 2024. Populasi penelitian seluruh kelas 10 sebanyak 40 orang. Sampel diambil secara purpose sampling sebanyak 40 orang. Penelitian ini merupakan penelitian kuantitatif, metode yang digunakan dalam penelitian ini adalah pre-expreimental design dengan bentuk one group pretest and posttest. Sebelum diberikan perlakuan terlebih dahulu dilakukan tes diagnostik untuk mengetahui kemampuan metakognisi siswa seberapa besar kegagalan metakognisinya dalam menyelesaikan masalah statistika. Selanjutnya dikelompokkan untuk kegagalan metakognisi tinggi, sedang dan rendah. Setelah diberikan perlakuan yaitu model pembelajaran berpikir induktif berbantuan GeoGebra diberikan posttest dengan soal yang sama seperti pretes berupa soal uraian materi statistika. Hasil penelitian menunjukkan pengaruh yang signifikan model pembelajaran berpikir induktif berbantuan GeoGebra terhadap kemampuan pemecahan masalah matematis siswa.

Abstract

This study aims to describe the influence of mathematical disposition on problem-solving ability through video-assisted learning in seventh-grade mathematics at a junior high school in Gunungsitoli City. The research employed a quasi-experimental design, with class VII-A as the experimental group (n = 32) receiving video-assisted instruction and class VII-B as the control group (n = 32) using conventional methods. Data were collected through problem-solving ability tests and mathematical disposition questionnaires, administered as pre-tests and post-tests. Analysis was conducted using t-tests and linear regression analysis. Results showed a significant improvement in problem-solving ability in the experimental class compared to the control class, with gain scores of 0.50 and 0.25 respectively. For problem-solving ability, the experimental class improved from a pre-test average of 67.34 to a post-test average of 83.78, while the control class improved from a pre-test average of 66.22 to a post-test average of 73.84. The mathematical disposition analysis yielded scores of 79.31 for the experimental class and 72.06 for the control class. Findings indicate that students who participated in video-assisted learning demonstrated significant improvement in problem-solving ability compared to the control group. Furthermore, students' mathematical disposition positively correlated with this improvement. This suggests that the video-assisted learning approach has potential in facilitating the development of mathematical problem-solving skills, while acknowledging the role of mathematical disposition in the learning process.
