Penelitian R&D ini bertujuan untuk memetakan kendala dasar dalam pembelajaran matematika di kelas VIII I SMP Negeri 1 Kedungadem serta mengembangkan Lembar Kerja Peserta Didik (LKPD) Digital Berbasis Contextual Teaching and Learning (CTL) materi Peluang yang valid, praktis, dan efektif. Pengembangan media ini menerapkan model 4-D yang dibatasi hingga tahap Develop berbantuan aplikasi Canva dan platform Liveworksheet. Data dikumpulkan melalui lembar validasi ahli, angket respon pengguna, serta instrumen tes hasil belajar (pre-test dan post-test), kemudian dianalisis menggunakan indeks Aiken’s V dan rumus Normalized Gain (N-Gain). Hasil penelitian dari aspek kelayakan menunjukkan bahwa LKPD Digital dinyatakan Sangat Valid dengan indeks Aiken's V sebesar 0,95 dari ahli materi dan 0,83 dari ahli media. Media ini juga memenuhi kriteria Sangat Praktis berdasarkan perolehan persentase angket respon guru sebesar 92,00% dan rata-rata respon siswa sebesar 82,04%. Selanjutnya, LKPD Digital terbukti Efektif dalam meningkatkan kompetensi kognitif siswa secara mandiri, terlihat dari lonjakan nilai rata-rata kelas dari 35,90 menjadi 82,23, serta perolehan nilai rata-rata N-Gain sebesar 0,718 yang masuk dalam kategori "Tinggi". Simpulannya, LKPD Digital berbasis CTL berbantuan Liveworksheet pada materi peluang ini sangat layak, praktis, dan efektif digunakan untuk mendukung pembelajaran mandiri siswa di sekolah.

Abstract

This R&D study aims to map out the foundational challenges in mathematics learning within class VIII-I at SMPN 1 Kedungadem and to develop a Digital Student Worksheet (LKPD) based on Contextual Teaching and Learning (CTL) for Probability material that is valid, practical, and effective. The development of this media applies the 4-D model limited to the Develop stage, supported by the Canva application and the Liveworksheet platform. Data were collected via expert validation sheets, user response questionnaires, and learning outcome tests (pre-test and post-test), which were then analyzed using the Aiken’s V index and the Normalized Gain (N Gain) formula. The feasibility aspect results indicated that the Digital LKPD was declared "Very Valid," with an average Aiken's V index of 0.95 from material experts and 0.83 from media experts. The media also met the "Very Practical" criteria based on the teacher's response percentage of 92.00% and the students' average response of 82.04%. Furthermore, the Digital LKPD proved "Effective" in enhancing students' independent cognitive learning outcomes, as evidenced by a substantial surge in the class average score from 35.90 to 82.23, supported by an average N-Gain score of 0.718, falling into the "High" category. In conclusion, this CTL-based Digital LKPD assisted by Liveworksheet on probability material is highly feasible, practical, and effective for supporting students' independent learning at school.
