Abstract

This study aims to determine the effectiveness of the buffer solution module based on the guided discovery learning model on student learning outcomes at SMAN 1 Nan Sabaris. The type of research is experimental research with one group pretest posttest design. The population in this study were students in class XI IPA at SMAN 1 Nan Sabaris in the 2022/2023 academic year. The sampling technique used is simple random sampling. In this study, students in class XI IPA 2 were selected as the sample class. The instrument used was a multiple choice test consisting of 20 questions with 5 answer choices. The test is carried out by administering an initial test (pretest) and a final test (posttest). The data obtained will be analyzed by N-Gain Test, Normality Test, and Hypothesis Test. Based on the research results, an N-Gain value of 0.62 is obtained in the medium category. The significance value in the hypothesis test obtained is smaller than the significant level of 0.05 (significant value 0.000 <0.05). Thus, it can be concluded that the use of a buffer solution module based on the guided discovery learning model is effective in improving student learning outcomes.

Abstract

Revolution industrial 4.0 learning is an digitalization of era, especially in the field of education so that technology-based teaching materials are needed that can increase student activity in learning. This study aims to analyze the validity, practicality and effectiveness of the acid-base titration e-module based on guided discovery learning for class XI SMA. The research method used is educational design research with a plomp model consisting of a preliminary research stage, a prototyping stage, and an assessment phase. The research subjects consisted of 8 validators, 6 people in the small group and 18 students in the field test. The research instruments used were validity questionnaires, practicality test questionnaires and student answer sheets on e-modules. Data were analyzed using Aiken's V formula and descriptive statistics. The results of the content validity test and obtained the average value of Aiken's V of 0.95 with a valid category. The results of the construct validity test and media expert validation obtained the average value of Aiken's V 0.89 in the valid category and 0.95 with the valid category. The results of the one-to-one evaluation show interesting e-modules, clear letters and easy-to-understand language. The results of data analysis in the small group test obtained an average percentage value of 87% in the very high category and 88% in the field test stage in the very high category. This data is evidenced by the ability of students to answer e-module questions at the small group stage and field test of . Based on the data analysis, it was concluded that the acid-base titration e-module based on guided discovery learning for class XI SMA was valid, practical and effective.
