EFEKTIVITAS PENGGUNAAN E-LKPD BERBASIS PROBLEM BASED LEARNING TERHADAP PENALARAN MATEMATIS SISWA DI SMP ISLAM AL FAQIHIL MUQODDAM SUI AMBAWANG

Abstrak

Tujuan penelitian ini adalah untuk mengetahui efektivitas E-LKPD Berbasis Problem Based Learning terhadap Penalaran Matematis Siswa. Penelitian ini menggunakan metode deskriptif kuantitatif. Sampel penelitian ini adalah 10 siswa kelas VII SMP Islam Al Faqihil Muqqoddam Sui Ambawang pada semester genap tahun ajaran 2024/2025. Pengumpulan data dalam penelitian ini menggunakan tes, angket, dan observasi. Soal tes yang digunakan adalah soal essay sebanyak 3 soal yang menguji kemampuan penalaran matematis siswa. Berdasarkan hasil penelitian dan analisis data dapat disimpulkan bahwa E-LKPD Berbasis Problem Based Learning terhadap Penalaran Matematis Siswa efektif karena terpenuhi keempat kriteria efektif yang dibuktikan dengan persentase masing-masing kriteria yaitu: 1.) Peningkatan atau N-Gain berada pada kriteria sedang, dari uji N-Gain diperoleh rata-rata siswa sebesar 0,64 berada pada kriteria sedang. 2.) Persentase kemampuan penalaran matematis siswa berada pada kriteria tinggi, dari rata-rata skor posttest yang diperoleh, 79 berada pada kriteria tinggi. 3.) Persentase siswa yang mencapai Kriteria Ketercapaian Tujuan Pembelajaran (KKTP) lebih dari 80% adalah 80,65% atau 25 siswa yang berada dalam kriteria tercapai. 4.) Respon siswa terhadap E-LKPD berbasis Problem Based Learning (PBL) sangat baik, hasil rata-rata persentase angket respon siswa adalah 85,97% dalam kriteria sangat baik. Jadi, dapat disimpulkan bahwa E-LKPD berbasis Problem Based Learning efektif untuk kemampuan penalaran matematis.

The purpose of this study was to determine the effectiveness of E-LKPD Based on Problem Based Learning on Students' Mathematical Reasoning. This study uses a descriptive quantitative method. The sample of this study was 10 students of class VII of SMP Islam Al Faqihil Muqqoddam Sui Ambawang in the even semester of the 2024/2025 academic year. Data collection in this study used tests, questionnaires, and observations. The test questions used were 3 essay questions that tested students' mathematical reasoning abilities. Based on the results of the study and data analysis, it can be concluded that E-LKPD based on Problem Based Learning on Students' Mathematical Reasoning is effective because the four effective criteria are met, as evidenced by the percentage of each criterion, namely: 1.) Increase or N-Gain is in the moderate criteria, from the N-Gain test, the average student obtained was 0.64 in the moderate criteria. 2.) The percentage of students' mathematical reasoning ability is in the high criteria, from the average posttest score obtained, 79 are in the high criteria. 3.) The percentage of students who achieve the learning objective achievement criteria (KKTP) of more than 80% is 80.65% or 25 students who are in the achieved criteria. 4.) The response of students to E-LKPD based on Problem Based Learning (PBL) is very good, the average result of the percentage of student response questionnaires is 85.97% in the very good criteria. So, it can be concluded that E-LKPD based on Problem Based Learning is effective for mathematical reasoning ability.
