Abstract

Penelitian ini bertujuan untuk mengetahui cara penerapan pendekatan Saintifik dengan bantuan alat peraga tradisional sehingga dapat meningkatkan hasil belajar matematika siswa kelas VIII SMPN 2 Kota Bengkulu. Jenis penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK) dengan tes hasil belajar siswa. Subjek penelitian ini adalah siswa kelas VIII G SMPN 2 Kota Bengkulu tahun ajaran 2019/2020 yang beranggotakan 35 orang siswa. Penelitian ini dilaksanakan dalam 1 siklus dengan materi penelitian adalah teorema Pythagoras. Hasil penelitian menunjukkan bahwa pendekatan Saintifik dengan bantuan alat peraga dapat meningkatkan hasil belajar matematika siswa. Peningkatan hasil belajar siswa dapat dilihat dari nilai rata-rata hasil belajar siswa pra siklus dengan siklus 1. Rata-rata hasil belajar matematika siswa pra siklus adalah 63.71 dengan ketuntasan belajar klasikal 42.85% dan pada siklus 1 rata-rata hasil belajar matematika siswa adalah 73.28 dengan ketutasan  belajar klasikal 68.57%.

Abstract

This study aims to develop a valid and practical LKPD (Student Worksheet) for use in the mathematics learning process on the topic of geometric transformations. The novelty of this research lies in the integration of the scientific approach and geogebra in teaching geometric transformations. The scientific approach has been proven to enhance problem-solving skills, while geogebra improves concept understanding and problem-solving abilities. The integration of both in the developed LKPD is expected to enhance students' problem-solving skills in an interactive and technology-based manner. The research method used is Research and Development (R&D) with the adaptation of the ADDIE development model. Data collection techniques in this study include interviews, observations, and questionnaires. The data collection instruments consist of interview guidelines, expert validation questionnaires, and response questionnaires. The results of the research have been analyzed and validated in terms of content, media, and language aspects. Additionally, an analysis of the practicality of the LKPD was conducted by teachers and students who used it in the learning process. The validity score for the content aspect from Validator 1 was 80%, categorized as valid, Validator 2 was 71%, categorized as valid, and Validator 3 was 80%, categorized as valid. For media and language aspects, the evaluation from Validator 1 was 66%, categorized as valid, Validator 2 was 61%, and Validator 3 was 85%, categorized as very valid. The analysis of LKPD practicality by teachers and students showed that the LKPD was considered practical, with a practicality score of 84.4% from the teacher (categorized as practical) and 90.8% from the students (categorized as very practical).
