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.
