2025-09-06T23:47:50+00:00

This study aims to develop an electronic module based on the STEAM (Science, Technology, Engineering, Art, and Mathematics) approach for acid-base material to enhance the quality of 21st-century chemistry learning. The background of this research lies in the lack of interactive and relevant learning media, especially in delivering acid-base concepts that are abstract and complex. This research employs a Research and Development (R&D) method using the 4D development model (Define, Design, Develop, Disseminate). The research subjects were twelfth-grade students at SMA Negeri 1 Percut Sei Tuan. Data were collected through interviews, observations, questionnaires, and tests. The instruments used include expert validation sheets to assess feasibility, teacher questionnaires to assess practicality, student questionnaires to assess responses, and achievement tests to measure effectiveness. The results showed that the developed electronic module met the criteria of being valid, practical, and effective. The module was created using Flip PDF Professional software and is equipped with interactive features such as videos, animations, and evaluation tools. Therefore, this module is deemed suitable to be used as an alternative learning medium for acid-base material.

Development Of Acid-Base Titration E-Module Based On Guided Discovery Learning For Class XI SMA

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.

Peningkatan Motivasi dan Hasil Belajar Peserta Didik pada Materi Larutan Penyangga melalui Implementasi E-LKPD berbasis Discovery Learning Terintegrasi Live Worksheets

2025-09-06T23:48:12+00:00

Metode pembelajaran konvensional dan kurangnya inovasi dalam pembelajaran berdampak pada rasa bosan dan kurangnya keaktifan peserta didik dalam proses pembelajaran. Kurangnya keaktifan disebabkan oleh rendahnya motivasi yang ada dalam diri mereka, sehingga dapat berdampak pada kurang maksimalnya hasil belajar. Permasalahan tersebut menuntut adanya inovasi yang mampu meningkatkan motivasi dan prestasi belajar peserta didik. Inovasi yang diberikan berupa implementasi E-LKPD berbasis Live Worksheets dengan model discovery learning terhadap materi larutan penyangga. Penelitian ini menggunakan metode pengumpulan data berupa lembar observasi dan tes, dengan subjek penelitian kelas XI sebanyak 36 peserta didik. Analisis data pada penelitian tindakan kelas dalam kerangka lesson study ini dilakukan dengan menggunakan teknik kuantitatif deskriptif. Hasil penelitian ini adalah pada siklus I, persentase motivasi belajar dan peserta didik yang memenuhi KKM berturut-turut adalah 27,78% dan 63,89%. Siklus II, persentase motivasi belajar dan peserta didik yang memenuhi KKM adalah 41,67% dan 72,22%. Selanjutnya, siklus III, persentase motivasi belajar dan peserta didik yang memenuhi KKM berturut-turut adalah 80,56% dan 86,11%. Secara keseluruhan, implementasi E-LKPD berbasis Live Worksheets dengan model discovery learning ini terbukti efektif dalam meningkatkan motivasi dan hasil belajar peserta didik pada materi larutan penyangga.

The Validitas dan Praktikalitas E-Chemmagz Etnosains Edisi Laju Reaksi SMA/MA untuk Meningkatkan Karakter Siswa

2025-09-06T23:48:26+00:00

This research is based on the limitations and monotony of learning resources in schools and the gap between educational practices and the character of students in schools. There is a need for learning resources that can be used as a solution to this gap. The purpose of this research is to develop an ethnoscience-based E-ChemMagz edition of reaction rate material to improve student character that is valid and practical. The research used the EDR (Education Design Research) research method with the utilization of the Plomp model. There are three stages carried out from this development, namely preliminary research, development (Development/Prototype) and assessment (Assessment phase). The instruments used in this study were validity and practicality sheets. From the final results of the study, it shows that the learning resources supporting the ethnoscience-based E-ChemMagz edition of the reaction rate are valid and practical. The data obtained from the developed product shows a V value of 0.87 with a valid category. The E-ChemMagz practicality test obtained a very positive response, with a percentage of 92.15% teacher response and 91.03% student response, each of which was classified as a very practical category used in learning.

The Validity and Practicality of E-LKPD in the Context of Socio-Scientific Issues Integrated with Scientific Argumentation of Electrolyte and Non-electrolyte Solutions

2025-09-06T23:48:34+00:00

Scientific argumentation skills play a crucial role in fostering 21st-century thinking skills and can be enhanced through socio-scientific contexts. Nonetheless, in the topic of electrolyte and non-electrolyte solutions, these skills have yet to be fully developed due to the absence of supportive learning contexts and teaching materials. Thus, this research aims to develop teaching materials in the form of an e-LKPD based on Socio-Scientific Issues (SSI) integrated with scientific argumentation for electrolyte and non-electrolyte solution topics in SMA/MA chemistry, as well as to assess their validity and practicality. This study employs Educational Design Research (EDR) with the Plomp development model. The validation process involved five validators, consisting of three lecturers and two teachers. The practicality test was carried out by nine students from SMAN 12 Padang. The validation results showed a score of 0.9, indicating a valid category, while the practicality test received student responses of 93% (very practical) and teacher responses of 89% (very pract1ical)..
