Abstract :

The research was conducted with the aim of developing valid, practical, and effective PBL learning materials for SPLTV subjects. The development of learning materials aims to improve students’ logical mathematical intelligence. This research is a type of development research with the 4D Thiagarajan model with the stages of define, design, develop, and disseminate. The learning materials produced include teaching modules, students worksheet, learning videos, test packages, and instruction manuals for using learning materials. Data collection was carried out using observation, questionnaire, and test methods. The results of the study showed that the learning materials developed were valid, practical, and effective. The level of validity can be seen from the validity value of each tool as follows, teaching modules of 3,79, students worksheet of 3,82, test packages 3,86, and instruction manuals 3,75. The level of practicality can be seen from the results of observations of the implementation of learning materials with an average of 3,43. The level of effectiveness of the materials can be seen from the results of student learning completion with a classical completion percentage of 84,6%, the N-Gain category is high with a student percentage of 97,29%, students’ logical mathematical intelligence activities are in the good category with a percentage of 84,33%, and the percentage value of student responses is 92,05% with a positive response.
