Abstract

The purpose of research is determine the effectiveness of teaching materials based contextual elements of group 15 for the course of inorganic chemistry. The research design is one group pretest-posttet only. Subjects were students of Chemistry Education University of Palangka Raya as many as 47 people. Based on the research results, is obtained percentage of graduated postes amounted to 93.6%, mean of  n-gain score is 0,54 (moderate), and the probability value (p) is 0,000, showed no significant difference between the pretest and posttest. Therefore, teaching materials element of group 15 based on contextual for inorganic chemistry course effective to improve student’s learning result. Penelitian ini bertujuan untuk mengetahui efektivitas bahan ajar unsur golongan 15 berbasis kontekstual untuk mata kuliah kimia anorganik. Desain penelitian yaitu one group pretest-posttet only. Subyek penelitian adalah mahasiswa Program Studi Pendidikan Kimia Universitas Palangka Raya sebanyak 47 orang. Berdasarkan hasil penelitian, diperoleh persentase jumlah lulus postes sebesar 93,6%, rata-rata n-gain score sebesar 0,54 kategori sedang, dan nilai probabilitas (p) yaitu 0,000 yang menunjukkan ada perbedaan secara signifikan antara nilai pretes dan postes. Oleh karena itu, bahan ajar unsur golongan 15 berbasis kontekstual untuk mata kuliah anorganik efektif meningkatkan hasil belajar mahasiswa.

Abstract

Science learning is closely related to practical activities. However, in certain conditions, practical activities cannot be optimally implemented due to limited tools and materials. PhET Interactive Simulation is a virtual laboratory application that can be utilized in science learning. The objectives of the Workshop on Using PhET Interactive Simulation at SMA Negeri 2 Kahayan Tengah are: 1) to improve teachers' understanding of technology-based learning through PhET Interactive Simulations; 2) to enhance teachers' skills in integrating PhET simulation-based technology into teaching modules; 3) to foster students' interest and motivation in science through learning experiences using PhET simulations. The stages of the workshop include: 1) Preparation Stage: Field surveys, planning, administrative setup, and preparation of supporting facilities; 2) Training Stage: Confirming attendance, conducting Phase I and Phase II training sessions. The outcomes of the workshop can be assessed from participants' satisfaction levels. The satisfaction rate among teachers was 99.5%, categorized as Very Satisfied. Additionally, the quality of teacher-created teaching modules was quite good, indicating that teachers improved their knowledge and skills in developing PhET-integrated teaching modules. Meanwhile, the student satisfaction level reached 87.88%, also classified as Very Satisfied, suggesting a significant increase in student interest and motivation in learning with PhET. In conclusion, this workshop proved to be highly important and beneficial, and it is hoped that similar programs will continue to benefit other teachers in the future.

Abstract

The Sustainable Development Goals (SDGs) present new challenges in global competition. This has been reflected in the Merdeka Curriculum, which incorporates green chemistry materials and project-based learning models. However, the lack of project-based learning module has become a significant obstacle in implementing this curriculum in schools. This research aims to determine the quality of the green chemsitry module that was developed. The product development follows the ADDIE model, though the research only covers the development stage. The initial product was reviewed by 6 experts to assess its quality. A Likert-scale questionnaire was used as the evaluation instrument, consisting of four components with a total of 33 statements. Meanwhile, the user response instrument consisted of 12 statements. The results showed that the project-based green chemistry module was deemed feasible for implementation in learning. This was evidenced by the ideal percentage from the product feasibility assessment by experts at 95.95%, which falls into the Very Good category. Furthermore, the small-scale trial results indicated an ideal percentage of 82.58% categorized as Good. This module supports the implementation of SDGs in reducing environmental pollution, as it includes several projects that students can apply in waste management.
