Efektivitas Discovery Learning Berbantuan Code.Org Terhadap Kemampuan Berpikir Kritis dan Motivasi Belajar Siswa

Abstract

This study was motivated by the low level of students' critical thinking skills and learning motivation in Informatics learning, particularly on programming algorithms. This study aimed to analyze the effectiveness of the Discovery Learning model assisted by the interactive digital learning media Code.org on students' critical thinking skills and learning motivation. The study employed a quantitative approach using a quasi-experimental method with a Pretest-Posttest Non-Equivalent Control Group Design. The sample consisted of 64 eighth-grade students at SMP Negeri 2 Gebang, with 32 students in the experimental class and 32 students in the control class. Data were analyzed using descriptive statistics, N-Gain, Independent Sample t-Test, and MANOVA. The results showed that the N-Gain of critical thinking skills was 0.7931 in the experimental class, categorized as high, and 0.3966 in the control class, categorized as moderate. The difference in critical thinking improvement was significant (t = -13.497; Sig. = 0.000). Learning motivation in the experimental class increased from a mean of 57.50 to 65.56, while the control class decreased from 57.56 to 54.84, with t = -4.502 and Sig. = 0.000. MANOVA results showed a significant simultaneous effect, with Pillai's Trace = 0.942, F = 496.058, and Sig. = 0.000. Thus, Discovery Learning assisted by Code.org was effective in improving students' critical thinking skills and learning motivation and had a significant simultaneous effect on both variables.
