Abstract

Purpose of the study: This study aims to evaluate the effectiveness of implementing the Talking Stick Cooperative Learning Model in improving the learning outcomes of Class X2 students at Rangsang 1 State Senior High School, located in Rangsang District, Meranti Islands Regency, on the topic of Chemical Bonds. Methodology: This study is a Classroom Action Research. The subjects of the study were 38 students of Class X2 at Rangsang 1 State Senior High School, located in Rangsang District, Meranti Islands Regency, consisting of 24 male students and 14 female students. The instruments used were learning activity tools and student learning outcome tests. The data analysis technique in this study employed descriptive analysis. Main Findings: Based on data analysis, the students' learning mastery before the intervention was 53.95, which increased to 64.74 in Cycle I, 73.42 in Cycle II, and 79.47 in Cycle III, showing a significant improvement. Thus, the data analysis results conclude that the implementation of the Talking Stick Cooperative Learning Model can enhance the chemistry learning outcomes of Class X2 students at Rangsang 1 State Senior High School, Rangsang District, Meranti Islands Regency. Novelty/Originality of this study: This study provides novel insights into the effectiveness of the Talking Stick Cooperative Learning Model in significantly enhancing student learning outcomes in chemistry, particularly on the topic of chemical bonds, within the context of a rural high school setting.

Abstract

Purpose of the study: This study aims to analyze students’ occupational health and safety (OHS) awareness and practices in chemical laboratory learning and to evaluate the effectiveness of integrating OHS principles into laboratory instruction to reduce safety risks and improve compliance. Methodology: This study employed a mixed-method approach using structured questionnaires, observation sheets, semi-structured interviews, and document analysis. Data were collected from undergraduate chemistry students. Quantitative data were analyzed using descriptive statistics, while qualitative data were analyzed through thematic analysis. Job Safety Analysis (JSA) was applied as a risk assessment tool. Main Findings: The results showed that 78% of students received safety training, but only 34% could identify hazard symbols correctly. Compliance with safety practices was low, including fume hood usage (25%) and chemical waste disposal (10%). JSA results indicated that 19% of laboratory activities were categorized as high to extreme risk levels. Novelty/Originality of this study: This study provides a novel integration of Job Safety Analysis (JSA) into chemical laboratory learning to systematically identify risks and improve safety practices. It also offers an evidence-based approach for embedding OHS into the curriculum, contributing to the development of a proactive laboratory safety culture.
