Abstract

The goal of this study is to develop reaction rate E-Worksheet based on RADEC learning model with the help of liveworskheet and analyze the quality of E-Worksheet developed. This Research and Development (R&D) study was developed utilizing the 4D development model, which includes the stages of Define, Design, Develop, and Disseminate.. The research was limited to the develop stage, namely validity test and practicality test. The instruments used were validity and practicality questionnaires. The validation process involved three lecturers from the UNP Chemistry Department and two chemistry teachers from Senior High School Negeri 1 Batang Kapas. The practicality test was conducted by two chemistry teachers and twenty-eight eleventh-grade students (Phase F) from the same school during the January to June 2024 semester. The validity test results were analyzed using Aiken's V, while the results of the practicality test with a percentage of the achievement score. From the results of the research analysis, the Aiken's V value was 0.87 with a valid category. The results of the practicality test from teachers and students respectively obtained a percentage value of 88% and 93%. The research findings indicate that the reaction rate E-Worksheet based on the RADEC learning model with the help of liveworksheet for Phase F of Senior High School is valid and practical, so it can be continued to the next research for effectiveness testing.

Abstract

The purpose of this study was to identify the effect of applying the RADEC learning model on shaping the profile of Pancasila students, learning outcomes, critical thinking skills, creative thinking skills, independence in learning, understanding of chemical multirepresentations, and understanding of concepts. This research is a literature review using data from research journal articles published in 2020-2023. Articles were collected using google scholar and researchGate with the keywords RADEC learning model and chemistry so that nine articles were analyzed. Based on the results of the analysis, it is known that the RADEC learning model can be applied to Voltaic cells, reaction rates, electrolyte and non-electrolyte solutions, atomic structure, buffer solutions and colloids. In addition, the application of this learning model can shape the profile of Pancasila students, critical thinking skills, creative thinking skills, and understanding of multirepresentation of chemistry.
