The impact of online platform-based RICOSRE on eleventh graders’ scientific reasoning skills in movement system and circulatory system

Abstract

Students must prepare themselves to be successful individuals in the twenty-first century by learning various skills and knowledge. Scientific reasoning is one of the required skills and must be acquired in the twenty-first century. Scientific reasoning skills can be enhanced by the use of a problem-based learning model, specifically RICOSRE. The purpose of this study was to investigate the impact of the online platform-based RICOSRE learning model on eleventh-grade students’ scientific reasoning skills in the human movement and circulatory systems at SMAN 1 Singosari. A quasi-experimental design was used in this investigation. The research sample comprised of two classes randomly drawn from class XI students at SMAN 1 Singosari during the odd semester of the 2019/2020 academic year. The syllabus, the lesson plan (RPP), the Learning Implementation Sheet, and the Learning Activity Unit all served as instruments for analyzing the independent variable. Meanwhile, the dependent variables were examined using the instrument used to assess scientific reasoning skills. Data collection was conducted using a pre-test and a post-test. The participants’ scientific reasoning skills were measured using a test developed based on the scientific reasoning rubric suggested by the Association of American Colleges and Universities. Similarly, the participants’ cognitive learning outcomes were also examined using a constructed test as needed. The participants’ test answers were analyzed using ANACOVA at a significance level of 0.05 to test the research hypotheses, followed by the LSD test. The findings indicated that there was a significant difference in scientific reasoning skills between students in the RICOSRE class and conventional class, with p (0.000) < (0.05). This result implies that the online platform-based RICOSRE learning model is one of the problem-based learning models capable of improving students’ scientific reasoning skills.
