Abstract

The periodic system of elements is one of the complex chemical materials. The results of previous research show that the learning achievement of boarding high school students has an understanding that is only limited to the macroscopic level. Visualization of chemical representation level requires high visual intelligence. Therefore, researchers developed a module of periodic system of elements as an independent learning media for high school boarding school students in improving visual intelligence. This study aims to analyze the validity, practicality, and effectiveness of the module. The type of research used is the ADDIE method with five stages, namely Analyze (analysis), Design (design), Develop (development), Implement (implementation), and Evaluate (evaluation). The module in terms of content and construction showed a very valid category. The results of observations of module implementation show a very practical category. The module is very effective to improve students' visual intelligence with an n-gain value of 0.753434. The results showed that the periodic system of elements module is feasible to use as a solution to improve students' visual intelligence.

Abstract

Creative thinking skills are one aspect of high-level thinking skills that students must have in 21st-century learning. Based on PISA 2022 data, the creative thinking skills of students in Indonesia are still relatively low. Therefore, this study aims to describe the feasibility of a project-based e-worksheet on green chemistry material to improve students' creative thinking skills. The type of research is Research and Development (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). Validity data is obtained from the validator's assessment using a validation questionnaire sheet. Practicality data is obtained from the results of the learner response questionnaire, which is supported by the results of observations of learner activities and observations of learning implementation. Practicality data is obtained from the results of the pretest and posttest of students' creative thinking skills. The validation results show that the content validity and construct validity of the e-worksheet are declared valid with mode 4. Practicality in terms of student questionnaire responses shows a very practical category with a material clarity percentage of 95.7%, ease of use of 100%, and usability of the e-worksheet of 100%. The effectiveness results are reviewed from the results of the N-gain score pretest and posttest of creative thinking skills in high categories. The N-gain on each indicator of fluency, flexibility, originality, and elaboration was 0.84, 0.82, 0.79, and 0.86. The results showed that a project-based e-worksheet on green chemistry material is feasible to use as a solution to improve students' creative thinking skills.
