ANALISIS KEBUTUHAN CHEMICAL FLANNEL BOOK (CFB) PADA MATERI SISTEM KOLOID

Abstract

Lack of innovation in learning media use so that students do not understand the concept of material in learning. So that to facilitate students' understanding, learning media needed that appropriate to the needs of students. This study aim to: 1) determine the validity of the Chemical Flannel Book (CFB) learning media on colloidal properties; This research use Research and Development research with 4D research model, which consists of define, design, develop, and disseminate. The data for this study came from two validators, a chemistry teacher and a chemistry lecturer. The results of media validation obtained 94.44% results in the valid category and the results of material validation obtained 90% results in the valid category. Based on the research, it can be concluded that the chemical flannel book media on colloidal system material declared valid.
