Abstract

This research aims to explore the effectiveness of teaching reading comprehension using two different learning media: Lumi Interactive and PowerPoint. This quantitative research approach focuses on comparing reading comprehension abilities between the experimental group and the control group. This study investigates whether students who teach using Lumi Interactive media show superior reading abilities compared to those using Powerpoint media. Data were analyzed using the Independent Sample T-Test. The results of data analysis from the experimental and control groups show the results of Sig. (2- tailed) 0.039 is lower than the alpha value of 0.05. It can be concluded that the null hypothesis (Ho) is rejected, which means the alternative hypothesis (Ha) is accepted. There is a significant difference in reading comprehension (reading perception) between students taught using interactive Lumi and those not using interactive Lumi. The average value of the experimental group was 82.00 while the average value of the control group was 77.90. Based on this analysis, it can be concluded that students in the experimental group showed higher skills than those in the control group, indicating that Lumi Interactive media in learning reading comprehension is effective.

Abstract

This research is motivated by the low level of critical thinking skills and the lack of student awareness regarding waste issues in their surrounding environment. One of the contributing factors is the use of learning materials that are not aligned with students' needs. Therefore, the purpose of this study is to develop a teaching module oriented toward the Problem-Based Learning model, supported by the 3R (Reduce, Reuse, Recycle) method, to improve the critical thinking skills of students in Phase B. This study adopts the Design and Development (D&D) method using the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). Data collection techniques include observation, interviews, questionnaires, and tests, with both qualitative and quantitative data analysis. The initial design of the module includes components such as the front cover, preface, table of contents, general information, core competencies, learning activities, conclusion, appendices, and back cover. Expert validation was conducted twice: before and after revision. The feasibility scores increased after revision, with assessments from subject matter experts improving from 94.2% to 99.4%, media experts from 91.4% to 94.8%, and learning experts from 86.4% to 90.6%. The overall average increased from 90.6% to 94.9%. Implementation of the module with fourth-grade Phase B students showed improved learning outcomes. The average pretest score increased from 49.7 to 80.9 in the posttest. The N-Gain score of 0.61 indicates a “Moderate” improvement. Therefore, this PBL-oriented module using the 3R method is effective in improving students’ critical thinking skills.
