Abstract

E-modul kimia unsur berbasis guided discovery learning telah dikembangkan dan dianalisis tingkat validitasnya untuk membantu proses pembelajaran peserta didik. Penelitian ini tergolong kepada Research and Development dengan model Plomp. The e-module divalidasi oleh tujuh orang validator ahli materi dan tiga orang ahli media. Instumen penelitian yang digunakan berupa angket validitas. Data dianalisa dengan menggunakan Content Validity Ratio (CVR) dan formula kappa Cohen’s. Hasil uji validitas konten diperoleh nilai rata-rata CVR sebesar 0,986. Hasil uji validitas konstruk dan validitas ahli media diperoleh nilai rata-rata momen kappa sebesar 0,90 dan 0,89. Data tersebut menunjukkan bahwa e-modul memiliki tingkat kevalidan yang sangat tinggi. Berdasarkan hasil penelitian, disimpulkan bahwa e-modul yang dikembangkan valid serta dapat dilakukan uji praktikalitas dan efektifitasnya.Kata Kunci: e-modul, guided discovery learning, kimia unsur

Abstract

This study aims to analyze the validity and practicality of the e-module being developed. This type of research is research and development (R&D) with the Plomp development model. 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. Jenis penelitian adalah Research and Development (R&D) dengan model pengembangan Plomp. Uji validitas e-modul dilakukan oleh empat dosen jurusan kimia FMIPA UNP  serta tiga guru kimia. Uji praktikalitas dilakukan oleh tiga guru kimia dan 32 siswa kelas XI SMAN 7 Padang tahun ajaran 2020/2021. Instrumen penelitian yang digunakan angket validitas dan  praktikalitas. Hasil validitas dianalisis menggunakan Content Validity Ratio (CVR) dan hasil praktikalitas menggunakan formula Aikens’V. Dari penelitian didapatkan hasil nilai rata-rata CVR validitas konten e-modul sebesar 0,95 (valid), validitas konstruk 0,82 (valid), praktikalitas e-modul pada guru 0,89 (praktis) dan pada siswa 0,82 (praktis). Berdasarkan hasil penelitian disimpulkan bahwa e-modul larutan elektrolit dan non elektrolit berbasis guided disscovery learning untuk kelas X SMA/ MA yang dikembangkan telah valid dan praktis.

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.
