Abstract

Permasalahan sosial dalam kehidupan seharusnya menjadi suatu hal yang menjadi sarana untuk meningkatkan kemampuan elaborasi mahasiswa. Penyajian isu dalam pembelajaran adalah suatu hal yang dapat dijadikan referensi dalam penyajian pembelajaran. Tahapan penyajian dalam LKM kinetika kimia mengikuti sintaks SSIBL yang terdiri dari tahap Ask, Find Out, dan Act yang diadopsi kedalam kegiatan pembelajaran pada LKM yakni Tahukah kamu sebagai tahapan awal pengenalan isu kepada mahasiswa, tahapan mari memprediksi untuk menggiring mahasiswa menemukan sebuah pertanyaan terkait isu, tahapan mari elaborasi yakni tahapan untuk mahasiswa mencari berbagai referensi untuk menemukan solusi dari isu, kemudian tahapan mengambil keputusan terkait dengan isu apakah mengemukakan alasan setuju atau tidak setuju. Penilaian akhir dari keputusan yang diambil yakni berdasarkan kategori alasan yang harus memenuhi kriteria alasan formal dan pertimbangan resiko. LKM divalidasi oleh ahli materi dengan mengahsilkan beberapa revisi untuk perbaikan konten LKM. Hasil validasi mendapat skor 0,95 dengan kategori sangat valid.

Abstract

Collaborative skills of students in the lecture process are still not optimal, whereas collaboration skills are the main skills that must be possessed by students in an effort to become quality individuals. This study aims to analyze the collaboration skills of students of the Biology Education undergraduate study program using the team-based project model. The research method used is descriptive quantitative. The subjects in the study were 40 first-semester Biology Education undergraduate students using the total sampling technique. The data collection method used was by distributing a collaboration skills questionnaire via googleforms. The questionnaire distributed contained 9 aspects of collaboration skills. The results of this study are the average percentage of skill indicators including, 1) positive collaboration interdependence of 87.80%; 2) face-to-face interaction of 69.37%; 3) personal responsibility of 88.75%; 4) communication skills of 90.62%; and 5) group work skills of 85.62%. So overall the collaboration skills of students who apply the team-based project model are included in the very good category.

Abstract

ABSTRACT The topic of Atomic structure is abstract which causing misconceptions on students required interconnectivity of the three levels of chemical representation at the macroscopic, submicroscopic, and symbolic levels. This study aims to determine the validity and practicality of Prompting question integrated PowerPoint-iSpring learning media on topic of atomic structure Research and Development (R & D) using the 4D as the instructional design model. The validity and practicality of the learning media developed wereobtained through research instruments in the form of validation and practicality questionnaires. Validation was carried out by 5 validators, while practicality was carried out by 30 students of class XI MIPA and two chemistry teachers. Data analysis techniques used were Aiken's V technique for validity and percentage technique for practicality. The results of analysis on validity datashowed an average Aiken's V value of 0.85 with the valid category. The result of analysis on practicality data showed value of 89% (for teacher practicality) and 86% (for students practicality) both showingvery practical category. Therefore, prompting questions integrated-PowerPoint-iSpring learning media developed is valid and practical.

Abstract

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.

Abstract

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.

Abstract

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)..

Abstract

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.
