Developing of a Teaching Module Based on Guided Discovery Learning Assisted by Augmented Reality (AR) on polyhedra Material for Students’ Conceptual Understanding in Phase D

/in /by

This study aims to address the issue of students’ low conceptual understanding in geometry learning, particularly in the topic of polyhedra, which tends to be abstract. Many students struggle to visualize three-dimensional shapes due to the lack of interactive, student-centered learning media. To overcome this challenge, a teaching module based on Guided Discovery Learning, supported by Augmented Reality (AR) with GeoGebra, was developed to enhance students’ mathematical conceptual understanding. The research employed a Research and Development (R&D) method using the 4-D model (Define, Design, Develop, and Disseminate). Data were collected through validation sheets, classroom observations, learning style questionnaires, student response questionnaires, and pre-test and post-test assessments. The results showed that the developed teaching module was valid, practical, and effective. The instrument validation scores for the teaching module were 4.47, for the LKPD (student worksheet) 4.30, and for the pre-test and post-test questions 4.40, all categorized as valid. Practicality was indicated by an implementation observation score of 4.47 (high category) and a positive student response rate of 87%. The module’s effectiveness was evidenced by a classical mastery percentage of 80.9% and an N-Gain score of 0.7 (moderate category), indicating a significant improvement in students’ conceptual understanding of polyhedra under the Kurikulum Merdeka. Based on these findings, it is recommended that the Guided Discovery Learning-based teaching module, supported by Augmented Reality, be used as an innovative alternative for geometry instruction to improve students’ mathematical conceptual understanding of the topic of polyhedra.

Development of Android-Based Interactive Physics Learning Media for Gas Kinetic Theory Materials

/in /by

This study aims to produce a decent Android-based interactive physics learning media, to know the user’s response to the learning media and to measure the effectiveness of the learning media. This type of research is development research using a 4-D model with 34 students as research subjects. The instruments used in this study were due diligence questionnaires by experts and physics teachers, student response questionnaires and tests. Based on the results of data analysis, the material expert validation was 96% with very feasible criteria, media expert validation was 96% with very feasible criteria and the physics teacher’s assessment was 80% with feasible criteria. Student responses to small group tests with 10 respondents obtained effective (2.8), productive (3), safe (2.9) and satisfied (3) results. Whereas in the large group test with 34 respondents the results were effective (3.12), productive (3.25), safe (3.01) and satisfied (3.17). Based on the calculation of the gain value, learning media is included in the medium category in the effectiveness of increasing students’ conceptual understanding with a value of 0.6.

Using Xerte Toolkit to Enhance Pre-Service Teachers’ Conceptual Understanding of Coordinate Geometry

/in /by

This study was to investigate the effect and explore students’ interest in using Xerte Toolkit in teaching and learning of Coordinate Geometry. In all, 50 pre-service teachers were involved in the study. The study adopted a mixed method approach. Semi – structured interviews as well as achievement test were the instruments used for data collection. The items in the achievement test were analyzed using statistical tools such as percentages, mean, standard deviation and t-test from Excel 2016 Analysis Tools. The descriptive statistics indicated that there was a significant difference between pretest and post test scores. The findings in this study posits that students’ interest in using Xerte Toolkits in teaching and learning Coordinate Geometry has increased and are ever ready to use Xerte Toolkit again in their studies.
