DEVELOPMENT OF DIGITAL BOOKS USING SIGIL TO ENHANCE STUDENT ENGAGEMENT IN DISTANCE LEARNING
Abstract
This study aims to enhance student engagement in distance learning by using digital textbooks that are valid, practical, and effective. This study employs the 4D model developed by Thiagarajan, with the population consisting of all students at STKIP Andi Matappa and a sample of 24 students enrolled in the calculus course in the mathematics education program at STKIP Andi Matappa. The research instruments included a textbook validity assessment sheet, a textbook practicality assessment sheet, and a student engagement questionnaire. The analysis techniques used included Gregory’s validity index, a practicality test, a t-test, and the ngain index. The results of the study indicate that (1) the validity score of the digital calculus textbook was 0.83, which means it falls into the “valid” category; (2) the practicality score of the digital calculus textbook was 1,660, which means it falls into the “practical” category; (3) There was an increase in student engagement in terms of cognitive, emotional, and behavioral engagement, and it fell into the moderate category because the p-value of the t-test was < α = 0.05 and the Ngain index was 0.72. A digital calculus textbook with a valid and practical design can effectively increase the engagement of STKIP Andi Matappa students in distance learning.
Penelitian ini bertujuan meningkatkan keterlibatan mahasiswa dalam pembelajaran jarak jauh dengan menggunakan buku digital yang valid, praktis, dan efektif. Jenis penelitian pengembangan model 4D Thiagarajan dengan populasi semua mahasiswa STKIP Andi Matappa serta sampel 24 mahasiswa yang mengambil mata kuliah kalkulus prodi pendidikan matematika STKIP Andi Matappa. Instrumen penelitian lembar validasi buku, lembar kepraktisan buku, dan angket keterlibatan mahasiswa. Teknik analisis berupa validitas gregory, uji kepraktisan, uji t serta index ngain. Hasil penelitian (1) Skor validitas buku digital kalkulus 0,83 berarti kategori valid; (2) Skor kepraktisan buku digital kalkulus 1660 berarti kategori praktis (3) Terdapat peningkatan keterlibatan mahasiswa baik dari katerlibatan kognitif, keterlibatan emosional, maupun keterlibatan perilaku, dan berada pada kategori medium karena hasil p-value uji t = < α = 0.05 dan ngain indeks =0,72. Buku digital kalkulus dengan sigil yang valid dan praktis, secara efektif dapat meningkatkan keterlibatan mahasiswa STKIP Andi Matappa dalam pembelajaran jarak jauh.
