Abstract

This study aims to produce students worksheet based of discovery learning to improve the problem solving ability of grade 8th student at Junior High School 4 Mataram on the subject of system of two variables linear equations that are valid, practical, and effective. This research is research and development (R&D) using ADDIE development model (Analysis, Design, Development, Implementation, And Evaluations). The subjects were 32 students. Data collection was carried out using a questionnaire and student problem solving abilities test. Data analysis  techniques use validity, practicality and effectiveness testing. The result shows that:1) Students worksheet based on discovery learning on the subject of system of two variables linear equations has valid categories, with the results was 84%. 2) The practicality at 90% was in excellent categories, and 3) The effectiveness at 0,71 was in good categories. Based on these results, it was concluded that students'' worksheets based of discovery learning have been valid, practical, and effective, and can be used in learning activities to improve problem solving ability of students.

Abstract

Learning trigonometry remains a challenge for many students due to teacher-centered instruction and limited opportunities for conceptual exploration. This issue highlights the urgency of implementing innovative learning models that actively engage students in constructing their understanding. This study aimed to improve students’ learning outcomes in trigonometry through the Guided Inquiry learning model. The research was conducted as Classroom Action Research (CAR) in two cycles, each consisting of two meetings, involving 30 Grade X vocational school students in Denpasar. Data were collected using essay tests to measure students’ competence in trigonometry and analyzed quantitatively based on cognitive test results. The findings showed a steady improvement in learning outcomes: prior to the intervention, only 46.67% of students achieved mastery with an average score of 61.33; in Cycle I, mastery increased to 66.67% with an average score of 73.90; and in Cycle II, mastery reached 80% with an average score of 81.97. These results indicate that the Guided Inquiry learning model effectively enhanced students’ understanding of trigonometric concepts and overall learning achievement. This improvement was influenced by the implementation of the Guided Inquiry learning model syntax, which encouraged students to develop a deeper understanding of trigonometry concepts. Therefore, it can be concluded that the Guided Inquiry learning model is effective in enhancing students’ learning outcomes.
