The effectiveness of e-modules based on discovery learning model integrated by probing-prompting questions in high school chemistry learning

Abstract

Fundamental laws of chemistry and voltaic cells e-modules that are valid and practical based on discovery learning integrated by probing prompting question has been developed. This research aims to analyze the effectiveness of e-modules based on discovery learning integrated by probing prompting questions on fundamental chemical laws and voltaic cell matter for high school learning. The type of research was pre-experimental with one group pretest-posttest design. The population and sample of this research were grade XII of HiliranGumanti high school and grade X Pratiwi high school. The sampling technique used purposive sampling technique. The research instrument was a test with 25 multiple choice questions. The result of analysis on effectiveness data showed an average N-gain value of 0.68 categorized as moderate on fundamental chemical laws matter, and 0.51 as moderate category in voltaic cell matter. The hypothesis test using the paired t-test sample obtained t-count > t-table, namely, 7.96 > 1.69 on basic chemical law material and 6.8 > 2.0 on voltaic cell material showing that the learning outcomes of students were enhanced after being given treatment of e-modules implementation. Therefore, e-modules based on discovery learning integrated by probing prompting questions on chemistry learning matters are effective in improving student outcomes.
