Abstract

This study aimed to develop a student worksheet (LKPD) based on the Logan Avenue Problem Solving–Heuristic (LAPS-Heuristic) approach and to examine its validity, practicality, and effectiveness in improving students’ mathematics learning outcomes in trigonometry. The study employed a Research and Development (R&D) method using the 4D development model, which consists of four stages: Define, Design, Develop, and Disseminate. The participants involved in the study were material experts, media experts, a mathematics teacher, and tenth-grade students from a senior high school in Sukoharjo. The results showed that the developed LAPS-Heuristic-based LKPD met the criteria for validity, practicality, and effectiveness in improving students’ learning outcomes. Based on evaluations by the material and media experts, the LKPD demonstrated a very high level of validity, with average validity scores of 0.8125 from the material expert and 0.898 from the media expert. In terms of practicality, the questionnaire results showed an average score of 88.125% from the teacher and 88.335% from the students, indicating that the LKPD was highly practical for use in learning. The effectiveness test using a t-test resulted in a significance value of p < 0.05, indicating a statistically significant difference in mathematics learning outcomes between the experimental and control classes. Students who used the LAPS-Heuristic-based LKPD achieved a higher average score than those in the control class. The experimental class obtained an average score of 79.7, compared with 71.5 in the control class. Overall, the findings indicate that the developed LAPS-Heuristic-based LKPD is effective in supporting and improving students’ learning outcomes in trigonometry.   Keywords: LAPS-Heuristic, Learning Outcomes, Worksheet
