Pengaruh Model Pembelajaran Berbasis Masalah Berbantuan Lembar Kerja Peserta Didik Berbasis Digital Terhadap Kemampuan Pemecahan Masalah Matematis Siswa ; Pengaruh Model Pembelajaran Berbasis Masalah Berbantuan Lembar Kerja Peserta Didik Berbasis Digital (E-LKPD) Terhadap Kemampuan Pemecahan Masalah Matematis Siswa

This study was motivated by students’ low mathematical problem-solving skills, the lack of innovative learning models, and the limited use of technology in learning media. The purpose of this research is to determine the effect of a problem-based learning model assisted by digital student worksheets on students’ mathematical problem-solving skills. This quasi-experimental research involved all eighth-grade students at one of the junior high schools in mataram city. The sample consisted of class VIII A as the experimental class, which received PBL with digital worksheets, and class VIII B as the control class, which received PBL with printed worksheets. Data were collected using a mathematical problem-solving test and analyzed using a t-test and effect size. The results showed that the use of digital worksheets had a significant effect on students’ mathematical problem-solving skills. The average score of the experimental class increased from 47.75 (pretest) to 70.12 (posttest), while the control class increased from 49.46 to 62.05. The t-test showed that at a 0.05 significance level. The effect size was 0.71, categorized as large, indicating that the applied model and media were effective. This study shows that digital worksheets in problem-based learning can enhance students’ problem-solving skills. ; Penelitian ini dilatarbelakangi rendahnya kemampuan pemecahan masalah siswa, model pembelajaran yang kurang inovatif, dan media pembelajaran yang belum memanfaatkan teknologi. Sehingga, tujuan penelitian ini adalah untuk mengetahui pengaruh model pembelajaran berbasis masalah berbantuan Lembar Kerja Peserta Didik berbasis digital (E-LKPD) terhadap kemampuan pemecahan masalah matematis siswa. Jenis penelitian ini adalah penelitian eksperimen semu dengan populasi semua siswa kelas VIII di salah satu SMP di Kota Mataram dengan sampel kelas VIII A sebagai kelas eksperimen yaitu pembelajaran dengan model pembelajaran berbasis masalah berbantuan LKPD digital dan kelas VIII B sebagai kelas kontrol dimana pembelajaran ...
