Abstract

This research aims to analyze the improvement in student learning outcomes and the responses of students who are taught using HOTS (Higher Order Thinking Skill) teaching materials based on the case method in solution material. This research was conducted on students of the chemistry education study program in the chemistry department, FMIPA, Medan State University. Research sampling was carried out using purposive sampling and a sample class of PSPK 23 A was obtained. The research instrument used in this research used test instruments to analyze improvements in learning outcomes and non-test instruments to analyze students' responses to the teaching materials used. The analysis technique for improving learning outcomes is carried out using the N-Gain test and to analyze student responses using a percentage scale. Based on the analyzed learning outcomes data, it was found that the increase in learning outcomes for students in the "Medium" category was 74.286% and for those in the "Low" category was 25.714%. In line with this, data on the results of student responses to HOTS teaching materials based on the case method that was used gave a positive response with a percentage rate of 91.3% which was included in the "Very Good" response category

Abstract

This study aims to develop an Augmented Reality (AR)-based chemistry e-module on hydrocarbon material for use in learning at SMAS Cerdas Murni. Hydrocarbons are considered a challenging topic for students due to their abstract nature. The research adopts a Research and Development (R&D) approach using the 4D model (Define, Design, Develop, Disseminate), but is limited to theDevelop stage. The development process involved expert validation and user responses to determine the module's feasibility. Validation results showed scores of 90.91% from material experts and 92% from media experts, both categorized as highly feasible. Additionally, teacher responses reached 99% and student responses 91.34%, indicating a strong positive reception. These resultsdemonstrate that the AR-based e-module is not only valid and practical but also effectively supports interactive and innovative learning. It is suitable for enhancing students’ understanding of abstract chemical concepts, particularly hydrocarbons, and shows promise for broader implementation in the classroom.
