Abstract

Learning using Android-based interactive learning media can actively engage students in the learning process. This study aims to improve students' computational thinking on heat material at SMAN 3 Kotabumi. The research method used in this study is experimentation. Experimental research is used to find the effect of a particular treatment on another under controlled conditions. The design used in this study was a pretest-posttest control group design. Data collection in this study was conducted during the use of Android-based interactive learning media to improve students' computational thinking on heat material in the learning process. The research subjects were 72 high school students, 36 in the experimental class and 36 in the control class. The results showed that this interactive learning media was quite effective in improving computational thinking skills, as seen from the significant difference between the average posttest scores in the experimental class and the control class based on the results of the Independent Samples Test, Sig. (2-tailed) = 0.00, with a significance level below 0.05. Based on the pretest and posttest data, the average N-Gain score was 0.61, categorized as moderate. Based on the research results and data analysis, the developed product can be used in mathematics learning.

Abstract

UTOPIA is a remotely operated robotic telescope developed by Observatorium Astronomi Itera Lampung (OAIL) to support astronomy education and research. Integrated with an Android-based control system, it enables remote observations and is applied across different levels of astronomy education. This study integrates UTOPIA with GraXpert, an open-source artificial intelligence tool for astronomical image enhancement through background extraction and noise reduction. A program involving 30 senior high school students was conducted through guided celestial observations, data acquisition, and collaborative image analysis. Participants were introduced to optical telescope principles, CCD imaging, and basic astronomical data processing, while GraXpert was used to enhance nebular image quality and visualization. The effectiveness of the program was evaluated using pre-test and post-test assessments. Results show a significant increase in understanding, with the mean score rising from 10.33 to 25.10 and a normalized gain of 0.75, indicating high conceptual improvement. Questionnaire results indicate positive learning perception, with most participants reporting improved understanding of nebular objects and better comprehension of the UTOPIA system, reflected in dominant positive responses. These findings demonstrate that integrating robotic telescopes with AI-based image processing supports astronomy education and improves students’ conceptual understanding through inquiry-based activities.
