The development of contextual teaching and learning based physics e-book to improve students mathematical representation skill on simple harmonic oscillation

Abstract

This research aims to produce an integrated physics e-book based on a contextual teaching and learning model that can be developed in physics learning on simple harmonic oscillation and improve students' mathematical representation skills. This research is an R and D with 4D models (define, design, develop and disseminate). The design of this research used pre-experimental with one group pretest-posttest. The samples of this research consisted of 26 students in Social Sciences class X as implementation class and 17 students in Natural Sciences class X as a modelling class at one of the Senior High Schools in the Special Region of Yogyakarta. The result of this research is the development of an integrated physics e-book with contextual teaching and learning models on simple harmonic oscillation topics suitable for use in physics learning with an average value of 3.75 in the excellent category. In addition, e-book media can improve students' mathematical representation skills with a value of sig (2-tailed) were 0.00 less than 0.05 in the modelling and implementation classes. This research can be used to implement online and offline learning in schools.
