Abstract

This research focuses on the development of interactive mobile learning media for science subjects in eighth-grade junior high school. The identified problems are the lack of student engagement and the limitations of easily damaged learning media. Additionally, educators face difficulties in using technology in the teaching and learning process. This study uses the research and development (R&D) method with a 4-D model. The product's validity was assessed by six experts—two media experts, two language experts, and two subject matter experts—who rated it as "Highly Valid" with an average percentage of 92%, 89%, and 97%, respectively. The practicality test showed that the media is very practical, with an average percentage of 87% from teachers and 96.7% from students. The effectiveness of the media was measured by the gain score, which showed a value of 0.62, categorized as "Moderate," and the average student learning outcome after using the media was 81.4, categorized as "Very Good." Based on these results, the interactive mobile learning media for science subjects in eighth-grade junior high school has been proven to be valid, practical, and effective in improving student learning outcomes

Abstract

This study aims to develop a valid, practical, and effective virtual laboratory as a solution to overcome limitations in physics education, with the expectation of improving both teaching quality and students' understanding of physics concepts. The research follows a Research and Development (R&D) approach using the 4-D model, which includes four stages: define, design, develop, and disseminate. The subjects of this study were 28 Phase-F students at SMA Negeri 11 Padang. The results include a virtual laboratory for Phase-F high school physics, validated with high scores: 89% for content validity, 97% for media validity, and 92% for language validity, all categorized as highly feasible. The trial for practicality among students scored 80.39%, categorized as practical, while the teacher trial scored 97%, categorized as highly practical. The effectiveness test showed significant improvement in student performance, with the average score increasing from 38.39 to 79.64. The N-gain score was 0.67, indicating moderate improvement. Based on the development and trials, it can be concluded that the virtual laboratory product for Phase-F high school physics is valid, practical, and effective for use in learning activities.

Abstract

Low student participation in IPAS learning, limited instructional media, and reliance on printed materials at SD Kartika I-10 Padang have negatively affected students’ understanding. This study aimed to develop an electronic student worksheet (E-LKPD) based on cooperative learning that meets the criteria of validity, practicality, and effectiveness for fifth-grade IPAS learning. The research applied a Research and Development (R&D) design using the ADDIE model, which includes Analyze, Design, Development, Implementation, and Evaluation. The subjects were 22 fifth-grade students. The development process involved analyzing needs, curriculum, and student characteristics, designing visual and content aspects of the E-LKPD, validating with media, material, and language experts, followed by product revision, implementation, and evaluation. Data were collected through expert validation sheets, teacher and student practicality questionnaires, and pretest-posttest. Results indicated high validity with an average score of 95%, while practicality was rated very practical by teachers (95%) and students (88%). Student learning outcomes improved significantly, with mean pretest and posttest scores of 56.59 and 90.45, respectively. The Wilcoxon test confirmed a significant difference (Z = -5.735, p < 0.05), reliability reached 0.80038 (reliable), and the N-Gain score was 0.79 (79.37%) in the high category. These findings conclude that the cooperative learning-based E-LKPD is valid, practical, and effective for enhancing IPAS learning in elementary schools.

Abstract

This study addresses the low level of active learning and inconsistent science achievement among primary school students. It aims to examine the effect of Technological Pedagogical and Content Knowledge (TPACK)-based instructional design on students’ learning activity and science performance. A quasi-experimental method with a nonequivalent posttest-only control group design was employed involving two classes: one taught using a TPACK-based approach and another using conventional instruction. Learning activity was measured through observation checklists and structured questionnaires, while science achievement was assessed through a multiple-choice test. Data were analyzed using descriptive statistics and an independent samples t-test. The results show that students in the TPACK group demonstrated notably higher levels of learning activity across visual, mental, and emotional dimensions compared to the control group. Their activity level was categorized as good, whereas the control group remained fairly good. Science test outcomes also revealed higher mean scores and lower score variance in the TPACK group. Statistical analysis confirmed significant differences between groups in both learning activity and science achievement. The study concludes that TPACK-based instructional design effectively integrates technology, pedagogy, and content to promote active engagement and enhance science learning outcomes in primary education.

Abstract

This study aimed to develop and evaluate a Google Sites-based learning medium for teaching Visual Arts to Grade X high school students. The research employed a Research and Development (R&D) approach using the ADDIE model, encompassing analysis, design, development, implementation, and evaluation phases. Data were collected through observation, interviews, questionnaires, and documentation. The developed media was assessed by subject matter, media, and language experts and determined to be highly valid. Practicality testing with teachers and students indicated that the media was very practical for classroom use. Effectiveness was evaluated using pre-test and post-test comparisons, showing a moderate improvement in students' cognitive learning outcomes, based on an N-Gain score in the medium category. These findings suggest that the Google Sites-based media is a valid, practical, and potentially effective tool for enhancing student engagement and understanding in Visual Arts education.
