Validity E-Module Electrolyte and Nonelectrolyte Based Problem Based Learning Terintegrated STEAM for SMA/MA

Abstract

Generally, students have difficulty understanding electrolyte and nonelectrolyte solution materials, because they are required to understand three representations including symbolic, macroscopic, and submicroscopic. With e-module, it’s hoped that it can increase students' interest in learning and e-module is designed so that students can study material independently and actively. This study aims to produce e-modules of electrolyte and nonelectrolyte solutions based on steam integrated problem-based learning for SMA / MA to analyze the validity of the e-module. Development model used in this study is a 4D development model. E-module validity test was carried out by two Chemistry lecturers of FMIPA UNP, one lecturer of FT UNP, and 2 chemistry teachers of SMAN 1 Payakumbuh.. Research instruments are in the form of validity questionnaires. Validity questionnaires were analyzed using the Aikens'V formula. From results of the study, the average score of Aikens'V was obtained at 0.97 with a very valid category. Based on the results, can be concluded e-module of electrolyte and nonelectrolyte solutions based on the resulting STEAM-integrated problem-based learning is valid. Therefore, this research can be continued to the stage of practicality and effectiveness testing, so that this e-module can be used in the learning process.
