Pengembangan Perangkat Pembelajaran Melalui Model Problem Based Learning Berorientasi Kemampuan Pemecahan Masalah Matematis pada Materi Fungsi Kelas X SMA

摘要

This study aims to develop learning tools in the form of RPP and LKS based on Problem Based Learning in the function material for high school students which is oriented to problem solving abilities. The quality of the product being developed is assessed based on the validity, effectiveness, and response of students to the LKS. The learning tool development procedure refers to the 4-D development model, namely Define, Design, Develop, and Disseminate (Distribution). Because of the limitations of the author, the writing is done up to the develop stage. The subjects of this study were 36 students of class X MIPA 1 as many as 36 students in SMAN 1 Karangwareng. The instruments used to measure the quality of learning tools developed are lesson plan assessment sheets and student worksheets to measure validity, test problem solving abilities to measure effectiveness, and questionnaires to students' responses to worksheets. Validity quality of learning devices meets valid criteria based on average RPP scores from five validators, namely 91% with very good criteria and an average score of LKS from five validators, namely 92% with very good criteria. The quality of the effectiveness of learning devices meets the effective criteria based on the results of pretest and post-test with an increase in completeness percentage from 2.8% to 72%. Student responses of 76% showed a positive response to learning equipment in the form of LKS.
