Meanwhile, the control group did not have a high gain criterion or 0% but moderate gain as much as 46.67% and low gain as much as 53.33%. The score of the calculation on the questionnaire of problem-solving skill of the experimental group students who used the website-based information system media was higher than that of the control group students who did not use such media where the score percentage of the former was 80.61% while that of the latter was 72.18%.
