Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran guided discovery learning dengan berbantuan LKPD terstruktur terhadap kemampuan pemahaman konsep matematis siswa. Metode yang digunakan pada penelitian ini adalah Quasi-Experiment atau eksperimen semu dengan post-test only control group design. Teknik pengambilan sampel yang digunakan pada penelitian ini adalah Cluster Random Sampling. Sampel penelitian yaitu siswa kelas X-3 dan X-2 di SMA Negeri 30 Jakarta. Kemampuan pemahaman konsep matematis siswa diukur menggunakan instrumen penelitian yaitu 5 soal uraian pada materi sistem persamaan linear tiga variabel yang telah valid dan reliabel. Berdasarkan nilai posttest, diperoleh besar rata-rata kelas eksperimen sebesar 80,88 dan simpangan baku sebesar 11,9, sedangkan pada kelas kontrol diperoleh rata-rata sebesar 71,62 dan simpangan baku sebesar 15,56. Hasil pengujian hipotesis menggunakaan uji-t dengan taraf signifikansi α=0,05, didapat bahwa nilai t_hitung=2,756 dan t_tabel=1,668 sehingga t_hitung≥t_tabel, maka tolak H_0 yang berarti rata-rata kemampuan pemahaman konsep matematis siswa yang menerapkan model pembelajaran guided discovery learning berbantuan LKPD terstruktur lebih tinggi dibanding siswa yang menerapkan model pembelajaran konvensional. Kemudian diperoleh nilai Cohen’s effect size sebesar 0,668 yang termasuk pada kategori sedang dengan presentase 73%. Berdasarkan hasil yang telah didapatkan, maka dapat disimpulkan bahwa terdapat pengaruh dari penerapan model pembelajaran guided discovery learning berbantuan LKPD terstruktur terhadap kemampuan pemahaman konsep matematis siswa SMA Negeri 30 Jakarta. Kata Kunci: model pembelajaran guided discovery learning, LKPD terstruktur, kemampuan pemahaman konsep matematis ABSTRACT MUTIAH. The Effect of Guided Discovery Learning Model Assisted by Structured LKPD on Students' Mathematical Concept Understanding Ability at SMA Negeri 30 Jakarta. Script. Jakarta: Mathematics Education Study Program, Faculty of Mathematics and Natural Sciences, State University of Jakarta, 2024. This study aims to determine the effect of guided discovery learning model with the help of structured LKPD on students' mathematical concept understanding ability. The method used in this research is Quasi-Experiment with post-test only control group design. The sampling technique used in this study was Cluster Random Sampling. The research samples were X-3 and X-2 grade students at SMA Negeri 30 Jakarta. Students' mathematical concept understanding ability is measured using a research instrument, namely 5 description questions on the material of the system of linear equations of three variables that have been valid and reliable. Based on the posttest scores, the experimental class average was 80,88 and the standard deviation was 11,9, while the control class obtained an average of 71,62 and a standard deviation of 15,56. The results of hypothesis testing using t-test with a significance level of α=0,05, obtained that the value of t_value=2,756 and t_table=1,668 so t_value≥t_table, then H_0 is rejected which means that the average ability to understand the mathematical concepts of students who apply the guided discovery learning model assisted by structured LKPD is higher than students who apply conventional learning models. Then obtained the Cohen's effect size value of 0,668 which is included in the medium category with a percentage of 73%. Based on the results that have been obtained, it can be concluded that there is an effect of the application of guided discovery learning model assisted by structured LKPD on the ability to understand mathematical concepts of SMA Negeri 30 Jakarta students. Keywords: guided discovery learning model, structured LKPD, ability to understand mathematical concepts
