This study aims to develop a discovery learning-based E-WORKSHEET using live worksheets to improve students' concept understanding ability on curved-sided space building material, test the validity of E-WORKSHEET, test the practicality of E-WORKSHEET, and see the improvement of students' concept understanding ability. The method used is Research and Development (R&D) using the ADDIE development model (Analyze, Design, Development, Implementation, and Evaluation). The research was conducted in class IX-F MTs Negeri 2 Kuningan with 32 students. Data collection techniques used in this study include interviews and needs questionnaires. The data analysis techniques used were the validity test, practicality test and N-Gain test. The validation test results from material experts showed a validity percentage of 88.17%, while the validation results from media experts reached a validity percentage of 96.53%. The practicality test results showed that the E-WORKSHEET implementation reached a practicality level of 94.84%, so it can be categorized as very practical. The technique to test the improvement of concept understanding ability is by giving pre-test and post-test questions to class IX-F students, as many as 32 students with details of the pre-test average of 15.16 and post-test average of 82.66. Based on the results of data analysis to find N-Gain, E-WORKSHEET is also able to improve students' mathematical concept understanding ability with an average N-Gain of 0.8 in the N-Gain category.
Penelitian ini bertujuan untuk mengembangkan E-WORKSHEET berbasis discovery learning menggunakan liveworksheets untuk meningkatkan kemampuan pemahaman konsep siswa pada materi bangun ruang sisi lengkung, menguji kevalidan E-WORKSHEET, menguji kepraktisan E-WORKSHEET, dan melihat peningkatan kemampuan pemahaman konsep siswa. Metode yang digunakan adalah Research and Development (R&D) dengan menggunakan model pengembangan ADDIE (Analyze, Design, Development, Implementation, and Evaluation). Penelitian dilakukan di kelas IX-F MTs Negeri 2 Kuningan dengan jumlah 32 siswa. Teknik pengumpulan data yang digunakan pada penelitian ini diantaranya wawancara dan angket kebutuhan. Teknik analisis data yang digunakan adalah uji kevalidan, uji kepraktisan dan uji N-Gain. Hasil uji validasi dari ahli materi menunjukkan persentase validitas sebesar 88,17%, sementara itu, hasil validasi dari ahli media mencapai persentase validitas sebesar 96,53%. Hasil uji kepraktisan menunjukkan bahwa implementasi E-WORKSHEET tersebut mencapai tingkat kepraktisan sebesar 94,84%, sehingga dapat dikategorikan sebagai sangat praktis. Teknik untuk menguji peningkatan kemampuan pemahaman konsep yaitu dengan memberikan soal pre-test dan post-test kepada siswa kelas IX-F sebanyak 32 siswa dengan rincian rata-rata pre-test sebesar 15,16 dan rata-rata post-test 82,66. Berdasarkan hasil analisis data untuk mencari N-Gain, E-WORKSHEET mampu meningkatkan kemampuan pemahaman konsep matematis siswa dengan rata-rata N-Gain sebesar 0,8 dalam kategori “tinggi”.
