Daftar Isi:
- This study was aimed at investigating whether the developed material could improve students’ generic skill. It was a developmental research (Research and Development) conducted at chemistry department FMIPA Unimed year of 2017/2018 on students who took chemistry reaction organic subjects. The materials consisted of stereochemistry, basic concepts of organic chemistry reactions, electrophilic addition reaction, nucleophilic addition reaction, nucleophilic substitution reactions, electrophilic substitution reactions, elimination reaction and free radical reaction. The students consisted of 4 classes which were taken by using “one group pre-test post-test design” with quasi-experimental method for 2 classes, 1 class as experimental group while other as control group. The data was collected by using scoring instruments of Badan Standar Nasional Pendidikan which had been modified. It consisted of content feasibility, language feasibility and presentation feasibility components as well as test of 25 questions of multiple choices to measure the improvement of students’ generic skills. As the implementation test, the material used was validated by the experts. The data were pre-test and post-test score of experimental and control class which were analysed by using N-gain formula by using SPSS version 20. The result of the study showed the developed material met BSNP criteria with quite valid criteria and no revision required. Thus, it is able to improve students’ generic skills.
