DEVELOPING LEARNING INSTRUMENTS BASED ON EXPERIENTIAL LEARNING MODEL ON SUBJECT OF CIRCLE FOR 8th GRADE STUDENTS OF JUNIOR HIGH SCHOOL

Abstract

The purpose of this research is to develop the mathematics learning instrument: syllabus, lesson plans (RPP), and student worksheets (LKPD) using the experiential learning model on circle subject for 8th grade students of junior high school (SMP) that is categorized as valid and categorized as practical. This research used Research and Development (R&D) model with ADDIE procedure; analyze, design, development, implementation, and evaluation. The research instruments used in this research were learning instrument validation sheets and student response questionnaires. The syllabus, RPP, and LKPD were validated by three validators and revised according to suggestions from the validator. The valid LKPD was then tested in two stages: the small and large groups. According to the validation data analysis of learning instruments, those were categorized as very valid, with the average score for syllabus being 4.24, for RPP was 4.18, and LKPD was 3,85. According to the result of student response questionnaires toward the LKPD practicality already the requirements of practicality with the percentage of students' response reaches 84% in large group trials. According to the result of data analysis and the discussion, it can be concluded that the learning instruments using the experiential learning model on circle subject were very valid, and the LKPD was very practical to be used by 8th grade students of junior high school.
