Abstract

This paper is the result of research and development that developed guided discovery based module on colloidal system topic for senior high school. Product developments revered to the 4D model (define, design, develop, and disseminate). Research instruments used were of questionnaires and learning outcomes test. The product was validated by experts and tested to a number of students in one of Senior High School in Padang, Indonesia. Data were analyzed qualitatively and quantitatively with descriptive technique and the statistical tests were done with the help of the Statistical Package for Social Science 16 Software. The result of validity and practicality analyzed by using kappa Cohen’s formula showed that developed module has very high validity category (κ = 0.89), very high category of the practicality on teacher response (κ = 0.87) and high category of the practicality on student response (κ = 0.71). The results of field trials obtained that the students' learning outcomes in experiment class is higher significantly than the control class. The research findings showed that the guided discovery learning based module developed was valid, practical and effective to use in chemistry learning in senior high school.
