Abstract

Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh model pembelajaran Discovery Learning berbantuan E-LKPD terhadap kemampuan pemahaman konsep matematis siswa kelas X SMA Negeri 31 Jakarta. Metode penelitian yang digunakan adalah metode eksperimen semu (quasi experiment) dengan desain penelitian posttest-only group design. Instrumen penelitian yang digunakan adalah instrumen tes kemampuan pemahaman konsep matematis berupa lima soal uraian yang telah dinyatakan valid dan reliabel. Teknik pengambilan sampel menggunakan Cluster Random Sampling sehingga didapatkan kelas X-6 sebagai kelas eksperimen yang diberikan perlakuan dengan menggunakan model pembelajaran Discovery Learning berbantuan E-LKPD dan kelas X-1 sebagai kelas kontrol dengan menggunakan pembelajaran konvensional. Berdasarkan hasil pengujian prasyarat analisis data setelah perlakuan, hasil tes kemampuan pemahaman konsep matematis siswa kelas eksperimen dan kelas kontrol berdistribusi normal dan bersifat homogen. Pengujian hipotesis statistik menggunakan uji-t dengan taraf signifikansi 5%, diperoleh nilai t_hitung=2,31 yang lebih besar dari t_((0,05, 70))=1,67 sehingga H_0 ditolak. Dengan demikian, rata-rata tes kemampuan pemahaman konsep matematis siswa kelas eksperimen lebih tinggi dari kelas kontrol. Hasil tersebut mengindikasikan bahwa terdapat pengaruh model pembelajaran Discovery Learning berbantuan E-LKPD terhadap kemampuan pemahaman konsep matematis siswa kelas X SMA Negeri 31 Jakarta. Berdasarkan Cohen’s Effect Size diketahui besar pengaruh model pembelajaran Discovery Learning berbantuan E-LKPD terhadap kemampuan pemahaman konsep matematis siswa adalah sebesar 0,5437 yang termasuk ke dalam kategori sedang. *****This study aims to determine whether there is an influence of the Discovery Learning learning model assisted by E-LKPD on the mathematical concept understanding ability of class X students of SMA Negeri 31 Jakarta. The research employed a quasi-experimental method using a posttest-only control group design. The research instrument was a mathematical conceptual understanding test consisting of five essay questions that had been validated and proven reliable. The sampling technique used was Cluster Random Sampling, which resulted in class X-6 being selected as the experimental group, receiving instruction through the Discovery Learning model assisted by E-LKPD, and class X-1 as the control group, which was taught using conventional learning methods. Based on the results of the prerequisite tests conducted after the treatment, the posttest scores of both the experimental and control groups were normally distributed and homogeneous. Statistical hypothesis testing using the t-test with a significance level of 5%, obtained a calculated t_count=2,31 which is greater than t_((0,05, 70))=1,67 so that H_0 is rejected. Thus, the average test of mathematical concept understanding ability of students in the experimental class is higher than the control class. These results indicate that there is an influence of the Discovery Learning learning model assisted by E-LKPD on the mathematical concept understanding ability of class X students of SMA Negeri 31 Jakarta. Based on Cohen's Effect Size, it is known that the magnitude of the influence of the Discovery Learning learning model assisted by E-LKPD on the mathematical concept understanding ability of students is 0.5437 which is included in the moderate category.
