PENGEMBANGAN E-COURSE UNTUK MENINGKATKAN KEMANDIRIAN BELAJAR SISWA KELAS X PADA MATA PELAJARAN INFORMATIKA

ABSTRACT Student self-regulated learning remains a challenge in Informatics education at SMK YPM 2 Taman, particularly as some tenth-grade students continue to rely on teachers and peers when carrying out learning activities. To address this issue, this study developed a Notion-based e-course that integrates learning materials, learning resources, activities, assignments, progress tracking, and reflection based on Zimmerman's self-regulated learning framework. The development process followed the ADDIE model (analysis, design, development, implementation, and evaluation), involving 70 students equally divided into experimental and control groups. Data were collected using Likert-scale questionnaires. Expert assessments yielded a product feasibility score of 94.29%, categorized as highly feasible, while student responses reached 96.67% in the one-to-one trial and 98.33% in the small-group trial. The research instrument was confirmed to be valid and reliable, with a Cronbach's Alpha coefficient of 0.973. The initial abilities of both groups were relatively equivalent (p = 0.986). Following the learning intervention, the experimental group's scores increased by 26.343 points, compared with 6.086 points in the control group. The posttest scores differed significantly (t = 11.022; p < 0.001), with a mean difference of 20.286 points. The experimental group's mean N-Gain was 0.6886 (moderate), exceeding the control group's 0.1450 (low). These findings establish the Notion-based e-course as a highly feasible learning resource with the potential to support student self-regulated learning. However, the difference in N-Gain between groups has not yet been directly tested statistically. ABSTRAK Kemandirian belajar siswa dalam pembelajaran Informatika masih menjadi tantangan di kelas X SMK YPM 2 Taman, terutama karena sebagian siswa bergantung pada arahan guru maupun teman ketika menjalankan kegiatan belajar. Untuk merespons kondisi tersebut, penelitian ini mengembangkan e-course berbasis Notion yang menata materi, sumber belajar, aktivitas, tugas, pemantauan progres, dan refleksi dengan mengacu pada kerangka self-regulated learning Zimmerman. Pengembangan mengikuti model ADDIE (analysis, design, development, implementation, dan evaluation), sedangkan pengujiannya melibatkan 70 siswa yang terbagi sama rata ke dalam kelompok eksperimen dan kontrol. Data diperoleh melalui angket skala Likert. Penilaian ahli menghasilkan kelayakan sebesar 94,29% (sangat layak), sementara tanggapan siswa mencapai 96,67% pada uji one-to-one dan 98,33% pada small group. Instrumen dinyatakan valid dan reliabel dengan Cronbach’s Alpha 0,973. Kemampuan awal kedua kelompok relatif setara (p = 0,986). Setelah pembelajaran, skor kelompok eksperimen meningkat 26,343 poin, dibandingkan 6,086 poin pada kelompok kontrol. Skor posttest berbeda signifikan (t = 11,022; p < 0,001), dengan selisih rerata 20,286 poin. Rerata N-Gain kelompok eksperimen sebesar 0,6886 (sedang), sedangkan kelompok kontrol 0,1450 (rendah). Temuan ini menempatkan e-course sebagai produk yang sangat layak dan berpotensi mendukung kemandirian belajar; perbedaan peningkatan N-Gain antarkelompok, bagaimanapun, belum diuji secara langsung.
