Abstract

This paper is intended to develop teaching materials on the material properties of the chemical solution Colligative Secondary Schools and the results of due diligence materials. This research is part of the research and development design to produce teaching materials. Stages of research are conducted, as follows: 1) A preliminary study in the form of analysis and mapping of the content and context; 2) packaging of teaching materials products; 3) validation and trials to determine the feasibility of the product. The teaching materials were developed based on the results of Herron’s concept analysis, standard textbook analysis as well as analysis of the material representation of the colligative nature of the solution referring to Gtizkia. Based on the result of the research, it is found that the product of teaching material has characteristic, in which, is connecting the three levels of chemical representation on the colligative nature of the solution using various modes of representation in the form of video, animation, image and text. Macroscopic representations of presentation of experimental phenomena and procedures, submicroscopic representations are visualized using text, images and video/ animation inserts that relate them to symbolic representations. The teaching materials are also equipped with examples of problems and exercises that connect three levels of representation. The results of validation and feasibility analysis show that the product of teaching materials is valid and feasible to be used as a learning resource in High School.
