PENGEMBANGAN BAHAN AJAR IPA BERBASIS PENDEKATAN SAINTIFIK PADA MATERI ENERGI DAN PERUBAHANNYA DI KELAS IV SEKOLAH DASAR

Abstract

This research is motivated by the lack of development of teaching materials carried out by teachers. The use of teaching materials that are commonly used is not optimal because it only uses ordinary textbooks which in delivering the material have not fully facilitated students to find their own learning experiences. The use of a scientific approach to teaching materials can make students actively learn to find their knowledge because of the various learning sequences starting from observing, asking, trying, reasoning and communicating. This research is a development research that aims to find out how to design science teaching materials based on a scientific approach, as well as to determine their feasibility based on the opinions of experts. The research was conducted using the Delphi method proposed by Linstone and Turoff. The steps are preliminary study, design, verification and final evaluation. The data collection instruments used were questionnaires, interviews and checklists. From the results of expert verification, it was found that teaching materials scored 95% and 91.6% from media experts in the "Very good" category, and 80% from material experts in the "Good" category. The average result of the assessment shows a value of 88.86% with the category "Very Good." That way, science teaching materials based on a scientific approach to energy materials and their changes in grade IV elementary school are declared "Very Appropriate" for use in learning.
