LOCAL CULTURE-BASED PHYSICS SMARTBOARD LEARNING FOR PROBLEM-SOLVING SKILL DEVELOPMENT: “NGADA” INDONESIAN TRIBE CASE STUDY

Abstract

Physics is often considered difficult due to its abstract nature, lack of student training in problem solving, and limited school resources, especially in Ngada Regency, Indonesia. This study aims to develop and evaluate the feasibility of the Physics SmartBoard application based on the local culture of "Ngada," focusing on product validity, practicality, and effectiveness in improving students' problem-solving abilities. The study used the Research and Development (R&D) method with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The instruments included validation sheets, user response questionnaires, and student problem-solving ability tests. The quantitative data were obtained from expert validation results, user trials, and analysis of problem-solving abilities before and after using the application. The results showed that the application met the criteria for high validity, according to experts, with a level of practicality that was considered very good by teachers and students. In addition, the effectiveness of the application in improving students' problem-solving abilities was in the high category, with a standard gain value of 0.12 in the control group and 0.455 in the experimental group. This application has the potential to be an innovative solution for physics learning in areas with limited resources.
