The e-module validity test was conducted by four lecturers from the Department of Chemistry, Faculty of Mathematics and Natural Sciences, UNP and three chemistry teachers. The practicality test was carried out by three chemistry teachers and 32 grade XI students of SMAN 7 Padang for the 2020/2021 school year. The research instrument used was a validity questionnaire and practicality. The validity results were analyzed using the Content Validity Ratio (CVR) and the practical results used the Aikens'V formula. From the research, it was found that the CVR average value of the e-module content validity was 0,95 (valid), the construct validity was 0,82 (valid), the practicality of the e-module for the teacher was 0,89 (practical) and for the students was 0,82 ( practical). Based on the results of the study, it was concluded that the e-module of electrolyte and non-electrolyte solutions based on guided disscovery learning for class X SMA / MA developed was valid and practical. Penelitian ini bertujuan untuk menganalisis validitas dan praktikalitas dari e-modul yang dikembangkan.

Guided Discovery

Discovery learning is a learning situation on wich the principle content of what is tobe learned is not give but must be independly discovered by student. The effectiveness of guided discovery learning model to improve students’ critical thinking skills uses 6 indicators, are: formulating problems, formulating hypotheses, analyzing date, providing alternatives, summing up, communicating and applying principle. The guided discovery learning model was included in the effective category in terms of: (a) Improvement (N-gain) of students’ critical thinking skills by 0.65 with moderate criteria and (b) Students respond positively to learning using guided discovery learning model and its learning tools on implementation.
