Development of Science Student Worksheet Containing Local Potential of Geplak to Realize Problem-Solving Skill for Junior High School Students

Abstract

This study aims to reveal a science student worksheet containing the development of geplak as a local potential that is appropriate in science learning, know the effectiveness of science student worksheet containing the development of geplak as local potential towards the students’ problem-solving skill, and the students’ responses after using science student worksheet containing the development of geplak as local potential. This study used the R&D method by 4D model (Define, Design, Develop, and Disseminate) with questionnaires for feasibility science student worksheet, pretest-posttest, and the questionnaire students’ responses of science student worksheet. The data were analyzed by four-scale score conversion, paired samples t-test, and gain score. The result showed that the science student worksheet containing the development of geplak as a local potential that was appropriate in science learning as very good (A), the science student worksheet effective to improve students’ problem-solving, these results were proven by the paired sample t-test with (2-tailed) showing less than α (0.05) and gain score on the mid-category level to 0.48, and students’ responses after used science student worksheet were obtained by very good (A) category.
