PENGEMBANGAN LKPD MENGGUNAKAN MODEL DISCOVERY LEARNING PADA MATERI BANGUN RUANG SISI DATAR SISWA KELAS VIII SMP IT NURUL ‘ILMI AINI BANDAR LAMPUNG TAHUN AJARAN 2021/2022

Abstract

The research aims to (1) The feasibility of the LKPD research product based on Discovery Learning on the flat-sided space building material for class VIII students in terms of the validity and student responses. (2) The achievement of learning outcomes in class VIII students after using LKPD based on Discovery Learning on the flat-sided building material. The stages in the research are analysis, design, development, implementation, and evaluation. Product validation was carried out by 6 expert lecturers in accordance with their fields. Then the LKPD was given a practical questionnaire to be responded to by class VIII students of SMP IT Nurul 'Ilmi Aini Bandar Lampung in testing the LKPD product. The results of material expert validation on aspects of the suitability of the material with KD, material accuracy, image accuracy, material order, and LKPD characteristics aspects all obtained a score of 3.6 with valid criteria. Validation of media experts in both the cover design and content design aspects obtained a score of 3.8 with valid criteria. The validation of linguists on aspects of sentence structure accuracy, understanding of messages and information obtained a score of 3.6 with valid criteria. After using the LKPD that has been developed students experience an increase in the completeness of mathematics learning outcomes from 30% to 72%. Thus, LKPD using the discovery learning model on the flat-sided space building material is feasible to be used as teaching material.
