PENGEMBANGAN MEDIA PEMBELAJARAN INTERAKTIF HAPPY CHEMIST PADA MATERI HIDROLISIS UNTUK MENGUKUR PEMAHAMAN KONSEP SISWA

Abstract

As advances in the world of education, information and communication technology make an extraordinary contribution to the development of science. 2013 curriculum development applies student centered learning patterns, interactive learning patterns, and multimedia-based learning patterns.

The research aims to developing flash-based instructional media are entitled happy chemist to measure student understanding of concepts in hydrolysis material. The research uses research and development types with the method that is modified 4D defining stage (define), design (design), and development (develop). The study was conducted at SMA N 1 Karanganyar, the sampling use purposive sampling technique. The sample are XI IPA 4 and XI IPA 6 class, each of which consists of 36 students. Results of the validation analysis of the feasibility of the media shows the percentage of media validation of 86.69 included in the criteria very well.
