Abstract

History instruction at the junior secondary school level remains predominantly teacher-centered and expository, limiting students’ active engagement and conceptual understanding. This study aims to develop a Virtual Museum Tour–based learning media using the Lapentor platform for seventh-grade prehistory materials and to examine its feasibility through expert validation. The research employed a Research and Development (R&D) approach based on the Alessi & Trollip development model, which consists of planning, design, and development stages. The research participants were seventh-grade students of SMP Widya Wacana 1 Surakarta. Data were collected through observation, interviews, documentation, and validation questionnaires administered to media and subject-matter experts. The results indicate that the Virtual Museum Tour media, designed in accordance with the Cognitive Theory of Multimedia Learning proposed by Richard E. Mayer, meets the feasibility criteria in terms of content accuracy, visual design, navigation, and multimedia integration. The developed product was deemed valid and suitable for use as a visual-interactive alternative in history instruction.

Abstract

The low level of Higher Order Thinking Skills (HOTS) among junior high school students in Indonesia, particularly in three-dimensional geometry, requires innovative instructional solutions. This study aims to investigate the effect of Augmented Reality (AR)-based learning media on the HOTS improvement of eighth-grade students in the topic of solid geometry at SMP Negeri 27 Surakarta. A quasi-experimental approach with a pretest-posttest control group design was employed. The sample consisted of 63 students (experimental group: n=31, control group: n=32) selected through purposive sampling. Data collection instruments were HOTS tests based on the revised Bloom's taxonomy (C4–C6), validated by experts. Data were analyzed using the Shapiro-Wilk normality test, Levene's homogeneity test, independent sample t-test, and N-Gain analysis. Results showed that the mean posttest score of the experimental group (75.11) was significantly higher than the control group (51.49). The independent sample t-test yielded a significance value of <0.001 (t = −11.348), leading to rejection of H₀. N-Gain analysis indicated an improvement of 60.31% (fairly effective category) in the experimental group versus 23.33% (ineffective category) in the control group. It is concluded that AR-based learning media significantly improves students' HOTS in solid geometry.

Abstract

This study investigates the effect of web-based game media, specifically Earthgames supported by the Wordwall platform, on the critical thinking skills of eighth-grade students in the topic of Earth Structure in the Natural Sciences (IPA) subject. A pre-experimental design using a one- group pretest-posttest approach was employed, involving 64 students from SMP Negeri 27 Surakarta during the 2025/2026 academic year. Data were collected through validated critical thinking tests covering indicators of interpretation, analysis, evaluation, inference, explanation, and problem-solving based on Facione's framework. Results showed a significant improvement in students' mean scores from 45.57 (pretest) to 67.27 (posttest). The hypothesis test using the Paired Sample t-test (Sig. < 0.001) confirmed a statistically significant difference, with an N- Gain score of 0.43 (moderate category). These findings indicate that Earthgames via Wordwall positively influenced students' critical thinking by providing interactive, visual, and game-based learning experiences. The media supports Mayer's Cognitive Theory of Multimedia Learning and aligns with the constructivist principles underpinning 21st-century science education.
