The inadequate science literacy and numeracy levels of class X students in the 2021/2022 academic year at SMA Negeri 1 Ajibarang in physics learning, particularly in the domain of renewable energy materials, can be attributed to the limited engagement of science literacy and numeracy in the available learning media. The internet's potential as a learning tool has not been maximally utilized, resulting in a suboptimal learning experience for Generation Z students. In addition, some digital platforms commonly used by teachers are still not optimal in accommodating learning due to several weaknesses, such as limited material and interactive features, as well as information that is prone to being missed during the online discussion process through chat. These problems can be solved by utilizing Nearpod-based interactive learning media. This study aims to analyze the effectiveness of the media and compare which media exploration is considered most effective in enhancing students' science literacy and numeracy. The study employed a pre-experimental approach, utilizing a pre-test and post-test design with three experimental groups. The results indicated that experimental groups A, B, and C enhanced science literacy and numeracy. The N-gain scores of these groups were classified as 'low', with N-gain scores of 0.15, 0.13, and 0.07, respectively, for experimental groups A, B, and C regarding science literacy. The numeracy literacy of experimental groups A, B, and C were 0.20, 0.18, and 0.01, respectively. The conclusion drawn from these data is that Nearpod media is effective in enhancing science literacy and numeracy in the context of renewable energy, especially in the explanation of scientific phenomena in science literacy and the utilization of concepts, facts, procedures, and reasoning in mathematics in numeracy literacy. The utilization of Nearpod in blended learning is more efficacious than its use in flipped learning and print, with an N-gain value of science literacy and numeracy. Keywords: nearpod, science literacy skills, physics numeracy literacy, renewable energy.

Penelitian ini bertujuan untuk menganalisis model pembelajaran kelas rangkap dengan mengintegrasikan konsep dan strategi pembelajaran inovatif, serta teknik manajemen kelas yang efektif dan adaptif. Metode yang digunakan adalah tinjauan pustaka, dengan menganalisis artikel jurnal yang terpilih dari berbagai jurnal ilmiah yang relevan. Hasil analisis menunjukkan bahwa model pembelajaran kelas rangkap memerlukan strategi pengajaran adaptif seperti pengajaran kolaboratif dan penggunaan bahan ajar lokal. Keterlibatan komunitas dan pelatihan guru memainkan peran penting dalam keberhasilan penerapan model ini. Tantangan signifikan termasuk manajemen waktu dan fasilitas yang terbatas manjadi faktor utama. Akan tetapi PKR telah terbukti meningkatkan keterampilan sosial dan kemandirian siswa. Kesimpulannya, penerapan PKR dapat menjadi solusi yang efektif jika didukung oleh strategi manajemen yang cermat dan kebijakan pendidikan yang mendukung, terutama di daerah dengan akses terbatas seperti daerah 3T.

The Merdeka curriculum organizes the physics subject into concept understanding and science process skills. However, based on interviews and observations at MAN IC Pekalongan, the development of process skills in physics learning is rarely facilitated due to the limited availability of learning media and time. This RnD research aims to develop digital learning media as an alternative solution to these problems. The analysis of learning media needs showed that teachers and students need Interactive E-Modules as learning media, applications of physics in everyday life such as STEM, and a Virtual Lab packaged with interactive and simple language. The E-Module was validated by several experts in material, learning media, and learning and was declared highly feasible with an average score of 4.5 out of 5. The posttest results showed an average score of 59.67 for both the experimental and control classes. The n-gain analysis demonstrated that the E-Module effectively improved conceptual understanding, with an n-gain value of 0.74 (high), and had a positive effect on process skills with an average value of 87.86 for the experimental class and 86.44 for the control class, with a significance value of 0.032 in the independent sample test of both classes.

This study examines prevalent misconceptions among students regarding the fundamental concepts of acids and bases, which often arise during the learning process. This study aims to pinpoint misconceptions held by pre-service science teachers in the realm of acids and bases; 117 university students from diverse educational backgrounds, enrolled in three distinct courses: Biology, Chemistry, and Physics from the Faculty of Education, participated in the study. Using a structured questionnaire, the research identified 11 misconceptions out of 26 items related to acid and base concepts among pre-service teachers, while 15 items showed a correct understanding. Notably, three misconceptions exhibit the highest prevalence, namely the universal indicator of strong alkali (71.7%), the calculation-related concentration of acids and bases (69.3%), and the procedural steps for preparing a solution with a specified concentration using the dilution method (65.8%). The analysis indicates that although pre-service teachers generally understand acid and base concepts well, some misconceptions persist. Additionally, correlations between gender, university major, and understanding of these concepts were found. Further global research is recommended to identify misconceptions among university students. Comprehensive research in Malaysia could help educators and students address these misconceptions in Chemistry education.

Renewable energy is a global concern and should be incorporated into education to raise awareness among younger generations, including in physics education. Educators have made various efforts to raise awareness of the importance of pursuing renewable energy. A breakthrough sought in this research is to incorporate collaborative learning into the science-technology-engineering-art-mathematics (STEAM) approach. Integrating STEAM into collaborative learning can simultaneously develop critical and creative thinking skills by exploring local resources to become renewable energy sources. The research involved 36 high school students who met the criteria for having a smartphone and accessing a reliable internet connection. These conditions are designed to facilitate students' producing essays and posters exploring renewable energy sources in their local area. The research design employs a one-group pretest-posttest approach to assess the effectiveness of this STEAM-based collaborative learning process. The data collected from tests that have undergone t-tests and N-gain analysis, triangulated with observation data and questionnaires, illustrates the progress made in improving students' critical and creative thinking abilities. In conclusion, the implementation of STEAM-based collaborative learning demonstrates the highest level of achievement in creative thinking. It enables the production of innovative mini-projects that critically analyze local resources available for national energy sources.
