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.

Abstract

This study aims to determine the effect of implementing the PBL model assisted by e-module media on learning motivation and the improvement of students' learning outcomes on the reaction rate material, as well as to determine the correlation between learning motivation and the improvement of learning outcomes. The sample in this study was selected randomly, with Class XI-MIA-3 as the experimental class and Class XI-MIA-5 as the control class. Hypothesis testing was conducted using an independent sample t-test with a significance level of α = 0.05. The hypothesis is accepted if the Sig. (2-tailed) value < 0.05. The results of t-test on learning motivation yielded a t-count value of 9.317 with a significance of 0.000 < 0.05, which means Ha is accepted and H0 is rejected. Testing on the pre-test data resulted in a t-value of -1.944 with a significance of 0.057 > 0.05. In contrast, the post-test results showed a t-value of 12.656 and a significance of 0.000 < 0.05. The experimental class outperformed the control class by an average difference of 24.833 points, with a 95% confidence interval ranging from 20.906 to 28.761. Thus, Ha is accepted and H0 is rejected. Furthermore, for correlation, referring to Guilford's criteria, in the experimental class, a very strong positive correlation was found between learning motivation and learning outcomes with a correlation coefficient of r = 0.847 and a significance of 0.000 < 0.01. Such a high correlation indicates that about 71.7% (r² = 0.717) of the variation in student learning outcomes can be explained by their level of motivation.
