Chemistry module based on guided discovery to improve critical thinking ability: development and trial results

Abstract

The aim of this research is to know the results of trials on chemical modules on thermochemistry chapter developed. The method used in this research is mixed method those are qualitative and quantitative method. Techniques used by giving a questionnaire with 12 statements include content, language, presentation, and graphics. In the end of questionnaire, the respondent allowed to write his/her suggestion to improve the better module. The trials are conducted in two stages: minor and major test. The test subjects were chemistry teachers and students in three public senior high school. Minor trial used 15 students and 3 teachers, while major trials have 30 students and 5 teachers. Quantitative method obtained results of minor test calculations 73.3% with quite category for students and 73.6% for teachers with quite category, major test results obtained 80% with good category for students and 81.6% for teachers with good category. Qualitative methods based on advice provided by teachers and students. There were revisions that obtain during these two stages those are the changing of cover’s colour and improving the icon in module.
