Development of physics teaching materials based-contextual by integrated local wisdom to improve mastery of physics concept

Abstract

This research is a development research that develops contextually based physics teaching materials by integrating local wisdom. This research has a role as the basis for the development of textbooks of physics of high economic value. This research intends to mastery of physics concept. The teaching materials developed using the R & D model with the development model used are Borg & Gall (1989) and Kemp & Dayton (1985) model consisting of; (1) research and data collection through survey, (2) planning, (3) preparation of printed materials in the form of student worksheets, (4) expert validity test, (5) product revision, (6) small field trial, (7) product revisions, (8) large-scale field trials, (9) final product revisions, and (10) dissemination and implementation. The trial of teaching materials was conducted by students of physics education program with one group pretest-posttest design. The results showed that the overall teaching materials that made are feasible to use. This is indicated by the validation result done by 3 experts are consecutively for assessment from content expert 84%, assessment of media expert 78% and percentage of assessment from a teacher of the lesson (practitioner) 87%. For legibility percentage of the average percentage of 94% which means it is in the easy category. Improved learning outcomes with the N-gain score: class A with a score of 0.81 and class B score of 0.80 with high criteria. And the response of students with equal to 76% is in category good enough.
