Pengembangan Perangkat Pembelajaran Geometri dengan Model Discovery Learning

Abstract

Implementation of learning activities with the 2013 curriculum requires teachers to design systematic and effective learning tools so that students are actively involved in the classroom. The discovery learning model is an active and creative learning model so that it can motivate students in the teaching and learning process. However, learning tools with discovery learning models that are in accordance with Permendikbud Number 14 of 2019 with a more practical, effective and student-oriented format are insufficient, so efforts are needed to help teachers provide these learning tools. This study aims to develop a valid learning device with a discovery learning model on curved 3D shapes for Year 9 students. The type of research used is development research which refers to the Plomp development model. The plomp model consists of the initial investigation stage, the design stage and the assessment stage. However, this research was only carried out until the design stage due to the limitations of social gatherings due to the COVID-19 pandemic. The data sources of this research are comments and input from the validator through the validation instrument sheet. The instruments used are lesson plan, student worksheet, and test validation sheets. Data analysis was carried out descriptively based on the recapitulation of all statements from the validator. This research produces one-page lesson plan, student worksheet and test that are valid. It is hoped that in the future, other researchers can test the practicality and effectiveness of the learning tools that have been produced.
