PENGEMBANGAN LEMBAR KEGIATAN PESERTA DIDIK (LKPD) BERBASIS PBL BERBANTUAN MATH CITY MAP PADA MATERI LINGKARAN DAN BUSUR LINGKARAN KELAS XI SMA NEGERI 2 SAMARINDA

Abstract

Improving the quality of mathematics learning is necessary to ensure students' in-depth understanding of the concepts. One approach is to develop innovative teaching materials. This research aims to develop and produce Student Activity Sheets (LKPD) based on Problem-Based Learning (PBL) using Math City Maps on the topic of circles and arcs. The research method used was Research and Development (R&D) with the ADDIE model. In the Analysis phase, results indicated that students experienced difficulty understanding the material on circles, necessitating an innovative LKPD based on PBL and Math City Map technology. The Design phase involved developing an initial format and storyboard. In the Development phase, the LKPD was validated by media and material experts with Aiken-V indices of 0.99 and 0.89, respectively, with an average of 0.94, categorized as "Very Valid." The Implementation phase included trials and practicality tests, with Aiken-V scores from students of 0.887 and 0.816 from practicing teachers, resulting in an average of 0.85, categorized as "Very Practical." The effectiveness of the Student Worksheet (LKPD) was assessed as "Very Effective" based on the improvement in student learning outcomes through pretests and posttests, observations of teacher and student activities (93.23%), and a paired t-test with a significance level of 0.000 indicating a significant difference. The evaluation stage was conducted formatively through revisions based on expert input and summatively based on student learning outcomes.
