Pengembangan LKPD Berbasis Kontekstual dalam Pembelajaran Fisika SMA Pada Materi Elastisitas Bahan

Abstract

Physics is a science that is usually found in everyday life. The presentation of learning physics, it will be easier if related to daily activities. Linking learning with everyday life is called contextual learning. Learning physics with a contextual-based approach is considered the most suitable to be used. There have been many studies regarding the development of student worksheet on the elasticity of this material. However, until now there has not been found student worksheet for material elasticity of materials with a contextual-based approach that is valid and practical to use. This contextual-based student worksheet development research refers to the 4-D research model (define, design, develop and disseminate) but without going through the dissemination stage. The validity of this contextual-based student worksheet was tested by two media expert validators which were then followed by an open trial. In the open trial, it was carried out online by giving a random response questionnaire to class XI high school students in the Gresik district. Data from the validity process and open testing were analyzed through descriptive quantitative. The results showed that the contextual-based student worksheet on the elasticity of this material obtained the validity results of the expert team with an average of 94% which was included in the very valid category. Furthermore, in the open trial stage, students gave a response by getting an average score of 98% which was classified as very good with practical meaning to use. Therefore, the contextual- based student worksheet on the material elasticity of this material is very feasible and practical to be used in the teaching and learning process in class XI high school with material elasticity material.
