Development of Electronic Module on Colligative Materials STEM Based Solutions (Science, Technology, Engineering, Mathematics) Using Kvisoft Flipbook Maker Application

. This research is motivated by the increasingly rapid development of science and technology, which requires Indonesia to continue to race to not only improve its infrastructure, but also to improve the quality of its human resources. In addition, the teaching materials used in lectres are still in the form of printed materials (not yet using electronic modules) and have not been integrated into STEM. The results showed that the electronic module on the colligative propreties of STEM based solutions using kvisoft flipbook maker application developed was declared very feasible with an average feasibility value of 92,34. While the practicality test was declared very practical by the lecture with an average practicality value of 94 and received a very good response from students with an average practicality value of 96,38 very practical category, without revision. In terms of effectiveness, it is declared effective with an N-gain value of 0,77 high criteria.
