Abstract

Students' understanding of the subject matter has a great influence on achieving the learning objectives especially in mathematical learning because students' critical thinking skills can be enhanced by learning mathematics using an inquiry-based learning model. The reasons for the improvement of students' critical thinking skills towards learning mathematics and can be called mathematical problem solving abilities are taken from the learning objectives listed in Permendiknas No. 22 Year 2006, in which the importance of this variable of mathematic problem-solving ability to each student is listed. This research uses qualitative research methods with facts found in the field. The data collection technique used is to give a description test to a high school student. The research population is the entire students of the eighth grade of 26 private high school students Jambi Medan. As a result of the application of the learning inquiry model in the private high school in Jambi Medan, students can respond well so that students are more active in the learning process. This study shows that the use of the Inquiry Based Learning learning model has an impact on the mathematical learning outcomes of students in high school.

Abstract

Pemahaman konsep matematika siswa SMA masih rendah karena pembelajaran yang berpusat pada guru dan kurangnya perangkat yang mendukung proses berpikir mendalam, sehingga pengembangan LKPD menjadi urgensi. Penelitian ini bertujuan mengembangkan serta menguji kelayakan dan efektivitas LKPD berbasis Collaborative Learning untuk meningkatkan pemahaman konsep matematika siswa kelas X SMA. Metode yang digunakan adalah Research and Development dengan desain One Group Pretest–Posttest pada 26 siswa. Hasil validasi menunjukkan LKPD sangat layak (Aiken’s V 0,92) dan reliabel (91,49%; r = 0,911). Instrumen tes juga valid (CVI 0,80). Penerapan LKPD meningkatkan pemahaman konsep secara signifikan dari 33,07 menjadi 94,62 dengan N-Gain 83,27% (kategori efektif). Kepraktisan LKPD berada pada angka 76,33%, menandakan perangkat mudah digunakan. Dengan demikian, LKPD berbasis Collaborative Learning efektif dan layak digunakan untuk meningkatkan pemahaman konsep matematika siswa SMA
