Abstract

Abstrak Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah dan kemandriain belajar dengan pendekatan STEM berbasis LSLC (Lesson Study for Learning Community). Subyek penelitian adalah enam  peserta didik kelas VII SMPN 1 Ngunut. Pemilihan subyek peserta didik berdasarkan angket kemandirain belajar. Penelitian ini tergolong penelitian kualitatif . Teknik pengumpulan data pada penelitian terdiri dari beberapa tahapan yaitu lembar observasi, angket kemandirian belajar, dan tes kemampuan pemecahan masalah matematika. Analisis data yang diigunakan pada penelitian ini yaitu dengan pengumpulan data, penyajian data, dan verifikasi data. Hasil penelitian ini menunjukkan bahwa aktivitas belajar peserta didik mengalami peningkatan. setiap pertemuan. Perkembangan tersebut dapat ditunjukkan dengan kemampuan pemecahan masalah dengan kemandirian belajar tinggi, mampu menyelesaikan masalah menggunakan empat tahap. Hanya tiga indikator yang dapat dicapai oleh peserta didik yang memiliki kemapuan pemecahan masalah matematika dengan kemandirian belajar sedang Sedangkan peserta didik dengan kemampuan pemecahan masalah matematika dengan kemandirian belajar rendah hanya memenuhi satu indikator saja.Kata kunci: Kemampuan pemecahan masalah; kemandiran belajaran; LSLC pendekatan STEM;  Abstract This study aims to describe problem solving skills and independent learning with a STEM approach based on LSLC (Lesson Study for Learning Community). The research subjects were six seventh grade students of SMPN 1 Ngunut. The selection of students' subjects was based on a self-learning questionnaire. This research is classified as qualitative research . The data collection technique in the study consisted of several stages, namely observation sheets, learning independence questionnaires, and mathematical problem solving ability tests. Data analysis used in this study is data collection, data presentation, and data verification. The results of this study indicate that the learning activities of students have increased. every meeting. This development can be shown by problem solving skills with high learning independence, able to solve problems using four stages. Only three indicators can be achieved by students who have mathematical problem solving abilities with moderate learning independence. Meanwhile, students with mathematical problem solving abilities with low learning independence only meet one indicator.Keywords: Problem solving ability, LSLC, learning independence, STEM approach

Abstract

 This study aims to see the effect of the Cabri 3d software on the mathematical critical thinking skills of SMA PGRI students in Pekanbaru in the 2021/2022 academic year on the material of the position of the line and the plane. This research is a quantitative study with a quasi-experimental method (quasi-experimental), with the population in this study being all students of class XII IPA PGRI PEKANBARU. The sample used is a saturated sample where class XII IPA 1 and XII IPA 2 are the research samples, which means that the entire population is the sample. The research design used was The Nonequivalent Post-Test Only Control Group Design. The data analysis technique used for the hypothesis is using the Mann Whitney u test with the results obtained a sig value of 0.00 0.05, so it can be concluded that there is an effect of Cabri 3d software on students' mathematical critical thinking skills. Keywords: Cabri 3d software, mathematical critical thinking skills, Geometry
