The Effect of RICOSRE via Online Platform on Tenth-Graders' Analytical Thinking Skills in Classification of Living Things

Abstract

Analytical thinking skills are skills that students must master in the 21st century. Analytical thinking skills can help students problem-solve and develop higher-order skills. However, the facts show that high school students in Indonesia have weak analytical thinking skills because the learning process in the classroom does not support the development of higher-order thinking skills. Online platform-based RICOSRE has the potential to develop analytical thinking skills. The purpose of this study was to examine differences in high school students' analytical thinking skills between RICOSRE students, PBL students, and traditional learning for students who learned via an online platform. This quasi-experimental study used a non-equivalent control group pretest post-test design. The research instruments consist of learning tools and essay tests. Ten essay questions were developed to examine the analytical thinking skills. The rubric for scoring the participants' answers was adapted from the University of Wisconsin 2018. The independent variable of this study consisted of online platform-based RICOSRE that was delivered to the experimental class, Problem Based Learning (PBL) that was used in the positive control class, and traditional learning that was implemented in the negative control class. The research sample contained six classes of tenth-grade students from SMAN 1 Singosari and three tenth-grade students from SMAN 7 Malang. The data were analyzed using ANCOVA, followed by the LSD test at a 5% significance level. The results indicated that the online platform-based RICOSRE learning model affected students' analytical thinking skills, as evidenced by a mean score of 72.642, higher than the scores obtained by the PBL or traditional groups.
