Pengaruh penggunaan LKPD digital berbasis multirepresentasi menggunakan liveworksheet terhadap keterampilan proses sains siswa

Abstract

This study investigates the effect of digital student worksheets (LKPD) based on multirepresentation using Liveworksheets on students' science process skills in Newton's law material. The research employed a quasi-experimental design with a pretest-posttest control group design involving 46 high school students (23 experimental and 23 control groups) selected through purposive sampling in one of the schools in Jambi province. The experimental group received treatment using digital student worksheets based on multirepresentation through the Liveworksheets platform, while the control group used conventional learning methods. Data collection utilized science process skills test instruments validated through expert validation. Statistical analysis included normality tests (Kolmogorov-Smirnov and Shapiro-Wilk), homogeneity tests (Levene's test), and independent samples t-tests. Results demonstrated that both groups had normal data distribution (p > 0.05) and homogeneous variances. Pretest analysis showed no significant difference between groups (t = 0.244, p = 0.808 > 0.05), indicating equivalent initial abilities. However, posttest analysis revealed significant differences (t = -2.257, p = 0.029 < 0.05), with the experimental group achieving higher scores. The N-Gain analysis showed significantly higher improvement in the experimental group (t = -3.187, p = 0.003 < 0.01). The novelty of this research lies in integrating multirepresentation learning through the digital liveworksheets platform, combining verbal, mathematical, graphical, and pictorial representations in Newton's law concepts. The findings contribute to physics education by demonstrating that digital student worksheets based on multirepresentation through the Liveworksheets platform effectively enhance students' science process skills through interactive, technology-integrated learning experiences.
