The Effectiveness of Android-Based E-Comics in Improving Students' Understanding of Mixture Separation Concepts in Grade X Vocational High Schools

Abstract

This research aims to explore the influence of Android-based electronic comics on tenth-grade vocational students’ understanding of the concept of mixture separation. A quantitative approach within a quasi-experimental design is utilized to conduct the study., involving two groups: an experimental class using e-comics and a control class using conventional learning media. The research subjects were 10th grade students at SMKN 7 Kota Batam, while the object of research was students' conceptual understanding of mixture separation material. Data were collected using a conceptual understanding test administered before (pretest) and after (posttest) the treatment.  The analysis of the data included normality and homogeneity tests, along with an independent samples t-test to evaluate differences in posttest outcomes between the experimental and control groups. Findings revealed that students in the experimental group achieved notably higher posttest scores than those in the control group. The t-test result was t (78) = 9.042 with a p-value of 0.000, which is below the 0.05 sig level, and the mean score difference was 14.800. These results confirm that the integration of Android-based e-comics sig enhanced students’ understanding of the concept.
