The Effect of Online RICOSRE on Tenth Graders' Problem-Solving Skills

Abstract

One of the critical skills that students must possess in the twenty-first century is problem solving. Problem-solving skills can be enhanced by using problem solving-based learning, namely RICOSRE. The RICOSRE learning model is composed of the following steps: (1) Reading, (2) Identifying the Problem, (3) Constructing the Solution, (4) Solving the Problem, (5) Reviewing the Solution, and (6) Extending the Solution. This research has been done during the online teaching period. The purpose of this study was to examine the effect of the online RICOSRE learning model on the tenth graders' problem-solving skills in Viruses and Bacteria at SMA Negeri 3 Malang. This quasi-experiment employed a pretest-posttest nonequivalent control group design. The research sample was made up of two classes, namely X MIPA El (36 students) and X MIPA Gl (34 students). The research instruments consisted of learning tools and essay tests. The participants' problem-solving skills were measured using an essay test administered in the pretest and post-test. The test answers were evaluated using a rubric adapted from the problem-solving rubric developed by the University of Southern Maine and Greenstein. The research data, which were in problem-solving scores, were analyzed using MANCOVA. The study results showed that students taught using RICOSRE experienced more effective problem-solving skills than those taught using conventional methods. Therefore, it was concluded that the online RICOSRE learning model affected students' problem-solving skills in Viruses and Bacteria at SMA Negeri 3 Malang. It was possible due to the RICOSRE syntax that contributed to improving students' problem-solving skills. In conclusion, RICOSRE implemented online can enhance students' problem-solving skills.
