Abstract

Chemistry lessons not only focus on mastering basic concepts, but also on developing critical thinking skills. The development of critical thinking skills in chemistry lessons has not been supported by good conditions in the field. This can be seen from the use of conventional learning models and teaching materials that are often used, namely only package books. So that to fulfill the effective learning process, teaching materials are needed that can help students achieve critical thinking skills. This research aims to produce a PBL-based LKPD to improve critical thinking skills in chemical bonding material phase F SMA/MA. This type of research is Educational Design Research with the Plomp development model. The subjects of this study are UNP chemistry lecturers, chemistry teachers of SMAN 1 Koto XI Tarusan and students of SMAN 1 Koto XI Tarusan. Data was obtained from validity questionnaires, practicality sheets, and pretest and posttest scores. The validation data was processed using Aiken's V formula. Based on the results found, it can be concluded that the LKPD developed is already in the valid category with an Aiken's V value of 0.88 and is very practical with a percentage of practicality based on teacher assessments of 92% and students of 91%. To see the improvement of critical thinking skills, pretest and posttest were carried out for students. Based on the results of the study, an N-Gain value of 0.7 was obtained. It can be concluded that LKPD is valid and very practical to be used in learning and is efficiently used to improve students' critical thinking skills.

Abstract

The change in the current curriculum, from the 2013 curriculum to an merdeka curriculum, creates obstacles for MGMP teachers in preparing the scope of material that must be delivered to students in order to achieve curriculum goals. Apart from that, the incomplete scope of the material will result in the teacher's availability of digital-based learning media not being met, even though there are already platforms that can support the development of learning media.Therefore, training in the development of digital-based learning media (Canva for Education) is needed for Solok Regency Chemistry MGMP chemistry teachers in order to support the implementation of the independent curriculum. Based on the training activities that have been carried out, it can be concluded that this activity is useful for increasing teacher competence in developing digital learning media

Abstract

Pasaman District is the largest corn producer in West Sumatra Province, one of the villages is Lingkuang Aua Bandarajo, where the majority of the population work as corn farmers. This amount is directly proportional to the amount of corn cob waste produced from agricultural activities. Based on the results of observations and interviews with local communities, it is known that the processing of corn cob waste has not been carried out optimally, because people tend to burn the corn cobs, which has an impact on environmental pollution. One solution that can be provided is to hold training on processing corn cob waste into charcoal briquettes. This PKM activity was carried out offline with 3 sessions, namely a session presenting material regarding business opportunities and how to make corn cob briquettes, practice accompanied by a team and independent practice. Through this PKM activity, it is known that there has been an increase in knowledge about corn cob briquettes by the youth of the village of Aua Bandarajo. The corn cob briquettes produced can be a source of renewable fuel and can also improve the economy of local communities.

Abstract

Learning has undergone a significant transformation in recent years. Technological advances have made it possible to use various digital platforms to support learning [1], [2]. In this era, the phenomenon of learning flexibility has become a top priority for educational institutions in various countries [3]. Flexible learning will help increase the effectiveness of learning and help students develop skills that are relevant to an increasingly complex world of work [4]. Learning flexibility in the era of digital technology in science education does not only include a combination of online or offline learning [5], but must also have a pedagogical framework that is oriented towards a balance of digital experience and scientific experience [6] [7] [8]. To achieve a balanced combination of digital and scientific experiences, teachers need to provide relevant resources, including interactive digital platforms and scientific tools. In addition, teachers must plan and implement practical activities that involve students in direct experience in the real world. To accommodate this, teaching materials are needed that implement a learning framework that integrates constructivist learning theory with connectivistic learning theory [9] [10] [11], so that science learning supported by various digital platforms can be more effective.However, conditions in the field show that the majority of teachers have not been able to implement this flexible learning framework and develop their teaching materials. Based on early observations at junior high schools in Agam Regency that the Community Service Team has carried out, the percentage of teachers who are able to implement the learning framework is only around 10%. The lack of socialization from the government and academics regarding the implementation of flexible learning frameworks in the digital era has also resulted in the low ability of junior high school science teachers in Agam Regency to be able to develop teaching materials that are able to facilitate flexible learning in the era of digital technology (only around 5%).The Community Partnership Program (PKM) in the form of Mentoring MGMP Science Teachers in Agam Regency in Developing Teaching Materials to facilitate Flexible Learning in the Digital Technology Era is a solution that needs to be implemented. The ultimate goal of this assistance is to increase teacher readiness to implement the flexible learning framework and develop teaching materials. The results of mentoring activities show that the final competency level achieved was 81% and digital teaching material products were obtained.

Abstract

Chemistry is a natural science discipline focusing on properties, structure, composition, chemical reactions. One of the studies on chemistry learning showed that more than 15.2% of students had difficulty memorising the elements in the periodic table. This is due to the many elements and ineffective learning methods. So, an interactive and fun learning method is needed. One of them is the WEIT (What Element Is That?) educational game, which is an innovation of the current game, Guess Who?. This research applies the R&D approach to the 4D development model and uses a quasi-experimental design. This research was conducted at SMAN 7 Padang, MAN 3 Padang City, & SMA Pembangunan Laboratorium Padang State University. The validity test obtained a validity value of 0.936 (valid category), with the results of the practicality test. The average value in the three schools is 0.955 (Very practical), 0.934 (Very practical), and 0.855 (Practical). In terms of effectiveness, the normality test was carried out with a p-value on the pretest of the experimental and control classes of 0.143 and 0.150, while on the post-test of the experimental and control classes were 0.149 and 0.168, indicating normally distributed data; t-test with a correlation value in the control class of 0.4221 (sufficient) and a very high value of 0.935 in the experimental class; finally the N-Gain test of the control and experimental classes was 50.07% (less effective) and 74.35% (effective), respectively. This indicates that WEIT games significantly improve students' learning outcomes on Periodic Table of Elements material. In addition, learner responses in the three schools showed a percentage of satisfaction, confirming that the WEIT game received a positive response from learners.

Abstract

Students’ understanding of acid-base concepts remains relatively low, as reflected by their low chemical literacy scores. One possible contributing factor is the suboptimal implementation of learning approaches that consider students’ individual learning styles. In fact, appropriate learning styles are believed to help students comprehend subject matter more effectively. However, studies that specifically examine the relationship between learning styles and chemical literacy are still limited. This study aims to investigate the relationship between students’ learning styles and their chemical literacy skills on acid-base material in Phase F of Senior High School. A correlational quantitative approach was employed, with data collected through the VARK learning style questionnaire and a chemical literacy test. The results showed that the kinesthetic learning style was the most dominant among students. However, the Spearman Rank correlation test revealed a weak and statistically insignificant positive relationship between learning styles and chemical literacy (r = 0.212; p = 0.239). These findings indicate that learning styles do not directly influence students’ chemical literacy. Further research is recommended to explore other factors that may have a greater impact on students’ scientific literacy achievement. ABSTRAKPemahaman peserta didik terhadap konsep asam basa masih tergolong rendah, salah satunya ditunjukkan dengan rendahnya nilai literasi kimia peserta didik. Salah satu dugaan penyebab belum optimalnya pendekatan pembelajaran yang memperhatikan gaya belajar peserta didik. Padahal, gaya belajar yang sesuai diyakini dapat membantu peserta didik dalam memahami materi dengan lebih baik. Namun demikian, kajian yang secara spesifik mengaitkan gaya belajar dengan literasi kimia masih terbatas. Penelitian ini bertujuan untuk mengetahui hubungan antara gaya belajar dengan kemampuan literasi kimia peserta didik pada materi asam basa fase F SMA/MA. Penelitian ini menggunakan pendekatan kuantitatif korelasional dengan teknik pengumpulan data berupa angket gaya belajar VARK dan tes literasi kimia. Hasil penelitian menunjukkan bahwa gaya belajar kinestetik merupakan gaya belajar yang paling dominan. Namun, uji korelasi Spearman Rank menunjukkan hubungan yang posistif lemah dan tidak signifikan antara gaya belajar dan literasi kimia (r = 0,212; p = 0,239). Temuan ini mengindikasikan bahwa gaya belajar tidak secara langsung memengaruhi literasi kimia. Penelitian lanjutan disarankan untuk mengeksplorasi faktor-faktor lain yang lebih berpengaruh terhadap pencapaian literasi sains peserta didik.

Abstract

Pembelajaran kimia di SMA kerap menjadi tantangan karena sifatnya yang abstrak, khususnya pada materi rumus kimia, tata nama, dan persamaan reaksi. Berdasarkan observasi di SMAN 11 Padang, banyak peserta didik belum mencapai ketuntasan belajar. Penelitian ini bertujuan menganalisis pemahaman konsep dan sikap peserta didik serta hubungan antara keduanya. Metode yang digunakan adalah deskriptif kuantitatif denngan teknik simple random sampling pada peserta didik kelas X Fase E. Data dikumpulkan melalui tes diagnostik Three-Tier dan angket sikap berbasis skala Likert yang dimodifikasi dari CLASS. Instrumen berupa tes diagnostik yang telah divalidasi oleh ahli dan uji reliabilitas, daya beda, serta indeks kesukaran sebelum digunakan pada tiga kelas sampel. Sementara itu, Instrumen angket sikap CLASS telah terbukti valid dan reliabel sehingga tidak perlu dilakukan pengujian ulang. Hasil menunjukkan pemahaman konsep tergolong rendah 21,46%, dengan tingkat miskonsepsi 67,38% dan tidak paham konsep 10,70%. Sebaliknya, sikap peserta didik terhadap pembelajaran kimia tergolong baik. Uji korelasi Pearson menunjukkan hubungan positif yang lemah antara sikap dan pemahaman konsep. Temuan ini menegaskan perlunya strategi pembelajaran yang lebih efektif untuk meningkatkan pemahaman konseptual.
