Pengembangan E-LKPD Berbasis Multimedia Interaktif Liveworksheet Dengan Pendekatan PMRI Pada Materi Kubus dan Balok

Abstract

This study aims to produce teaching materials in the form of E-LKPD based on PMRI approach on Cube and beam material that is valid, practical, and has a potential effect on the ability to understand mathematical concepts of students in Class VIII of SMP Negeri 18 OKU. The research method used is a research development method consisting of preliminary stage (analysis stage and design stage) and prototyping stage using formative evaluation flow (self evaluation, expert review, one-to-one, small group, and field test). Data collection was conducted using questionnaires, interviews and tests. The results of this study are: (1) E-LKPD based on PMRI approach developed qualitatively valid seen from the comments and suggestions of the validator, in addition quantitatively with the results of the validation sheet analysis by obtaining an average score of 80.9 at the expert review stage. (2) E-LKPD based on PMRI approach developed very practical qualitatively and quantitatively by obtaining an average score of 84 at the one-to-one stage, 88 at the small group stage and 88 at the field test stage. (3)E-LKPD based on PMRI approach developed has a potential effect on the ability to understand mathematical concepts with an average value of 73.8.
