PENGEMBANGAN MEDIA FUN THINKERS BOOK PADA PEMBELAJARAN IPAS KELAS III DI SD NEGERI TANAH MERAH

Abstract

The problem in this study is that science learning is still centered on the delivery of
material by the teacher so that students are not actively involved in the learning
process of natural and artificial appearances material. The purpose of this study is
to determine the development process, expert validation, practicality, and
effectiveness of the Fun Thinkers Book media. The method used in this study is
Research and Development (R&D) with the ADDIE model which consists of five
stages: analysis, design, development, implementation, and evaluation. The
research subjects were 13 thirdgrade students of Tanah Merah State Elementary
School. Data collection instruments include observation sheets, interviews,
validation questionnaires (material, language, and media experts), teacher and
student response questionnaires, and pretest and posttest tests. The results of the
study showed a 100% validation of the material with a “very high” criterion, 92% with
a “very high” criterion for linguists, and 100% with a “very high” criterion for media
experts. In the implementation phase, the teacher response rate was 94% with a
“very practical” criterion, and the student response rate was 92.30% with a “very
practical” criterion. The trial results showed that the N-Gain value for the pretest and
posttest was 0.82 with a “high” criterion, and the N-Gain percentage was 81.67%
with an “effective” criterion. It is recommended that schools with this media
development will increase student enthusiasm, teachers are expected to be able to
use the media, and future researchers are expected to continue developing the
media with more diverse variations.
