Validity of Inquiry-Based Buffer Solution E-Module STEAM Integrated Supervising for SMA/MA

Abstract

In general, students have difficulty understanding this buffer solution material. This is because the buffer solution material requires the ability to think critically in solving problems. This study aims to produce STEAM integrated buffer solution e-modules to reveal the level of validity and practicality of emodules. With the e-module, it is hoped that it can increase student’s interest in learning and the e-module is designed so that students can study the material independently and actively. The development model used in this study is the 4-D model. The validity test of the e-module was carried out by two Chemistry lecturers at FMIPA UNP, one lecturer at Faculty of Engineering UNP, and 4 chemistry teachers at SMAN 1 Bukittinggi. The practicality test was carried out by 2 chemistry teachers and 30 class XII students at SMAN 1 Bukittinggi in the 2022/2023 academic year. The research instrument is a validity and practicality questionnaire. The validity questionnaire was analyzed using the Aiken V formula and the practicality questionnaire was analyzed using descriptive statistical percentages. From the research results, it was found that the average value of Aiken V was 0.83 with a valid category. Based on the research results, it can be concluded that the e-modul is valid. Therefore this research can be continued to the effectiveness test stage, so that this e-module can be used in the learning process.
