The making of interactive multimedia orienting toward the three levels of representation in alcohol reaction

Abstract

Alcohol reaction is one of the concepts in organic chemistry, which has macroscopic, submicroscopic, and symbolic characteristics. Alcohol reaction is usually displayed in macroscopic and symbolic representation only, while in fact should be displayed in submicroscopic representation as well. This 'research and development' research aims at creating interactive multimedia that can display the three levels of representation on alcohol reaction and determine its feasibility level. The research results show that the product can display the three levels of representation in alcohol reaction. The macroscopic representation is presented with experimental video of alcohol reaction. The submicroscopic representation is presented with the animation of alcohol reaction mechanism. The symbolic representation is presented with the equation of alcohol reaction. Furthermore, the validation is done through the consideration of 4 experts and the feasibility test involving 15 college students. The result of the validation and feasibility test concludes that interactive multimedia is valid and feasible to be used in learning chemistry.
