Abstract

Low learning motivation among elementary school students remains a major challenge in science education. This study aimed to investigate the effect of using ice breaking activities on students’ learning motivation in science classes. A quasi-experimental design was employed with two groups of fifth-grade students in an elementary school in West Sumatra, Indonesia. Data were collected through questionnaires and analyzed using the Paired Sample t-test. The findings revealed that the average motivation score of the experimental group increased from 49.84 (pre-test) to 82.63 (post-test), while the control group showed a smaller improvement. The t-test result (t = 3.84, p < 0.05) indicated a significant effect of ice breaking on students’ learning motivation. These findings suggest that incorporating ice breaking techniques can enhance students’ engagement and focus during science learning, making lessons more dynamic and enjoyable. Future research may explore different types of ice breaking activities and their impact on other cognitive or affective learning outcomes.

Abstract

There still needs to be more research on the potential analysis of the development of ethnoscience-based science literacy modules in chemistry learning using bibliometric tools. Ethnoscience-based science literacy modules still need to be found and used in chemistry learning. This research aims to analyze the novelty and effectiveness of ethnoscience-based science literacy modules in chemistry learning. The subject of this research is a science literacy module based on ethnoscience in chemistry learning. In this study, the researchers also analyzed articles that have been filtered based on topics based on local wisdom-based science literacy modules. The analysis contains several components: title, year, doi, author, method, outcome, and conclusion. The research uses an approach that uses the method of Systematic Literature Network Analysis (SLNA) assisted by bibliometric tools as the medium used in analyzing the article. The data obtained was many articles from the SCOPUS database, which had previously defined some criteria for capturing it. The criteria are related to the year of publication, keyword, and language selection. The application used in this study is the VOS Viewers application. The results show that research related to ethnoscience-based science literacy modules in chemistry learning is still highly feasible, given the numerous constraints in some schools. However, it should be noted that ethnoscience-based science literacy cannot replace scientific literacy globally because of the global literacy capabilities needed in everyday life.

Abstract

Redox reactions are important in many physiological processes. Oxidation numbers are commonly used for balancing redox reactions and understanding metabolic reactions. When oxidation number cannot be assigned, it is difficult or sometimes even impossible to understand the biochemical redox reactions. This article applies the electrical charge method, which can balance redox reactions when the oxidation number is unknown. It uses H+, O, H2O, and electric charge as balancing devices. This method allows the net-charge to be quantified, redox terms to be defined, and metabolic redox reactions to be classified and understood. The net-charge is also a new electron-counting parameter for understanding biochemical redox reactions.

Abstract

Cognitive learning outcomes are important basic skills that students must master. Science learning must be designed so that it can optimally provide students with the cognitive dimension. The importance of cognitive learning outcomes is in contrast to conditions in the field. Students' cognitive abilities in science learning are still low, especially at levels C2, C3 and C4. Observation results at Ihsanul Fikri Mungkid IT Middle School show that students' cognitive learning outcomes are still below the specified average, namely 78. The aim of this research is to analyze the effectiveness of learning using the Argument Driven Inquiry model in improving junior high school students' cognitive learning outcomes. This research uses a quantitative approach of the Quasi Experiment type, data analysis is carried out using the Mann Whitney test, N-Gain test, and effect size test. The research results show that the Argument Driven Inquiry (ADI) learning model is effective in improving the cognitive learning outcomes of junior high school students with an N-Gain of 0,7444, which is in the high category.
