Abstract

This study aimed to examine the implementation of the Student Teams Achievement Division (STAD) cooperative learning model supported by Wordwall media in improving students’ participation and learning outcomes. The research subjects consisted of 25 third-grade students of class IIIA at SD Negeri 11 Mataram. This study employed Classroom Action Research (CAR) based on the Kemmis and McTaggart model, which includes the stages of planning, acting, observing, and reflecting, and was conducted over two learning cycles. The research instruments comprised observation sheets and individual evaluation tests. The results indicated an improvement in students’ learning participation. The level of learning participation in the pre-cycle stage was 59%, which increased to 74% in the first cycle and further rose to 87% in the second cycle. The increase in learning participation had a positive impact on students’ learning outcomes, which showed progressive improvement. In the pre-cycle stage, the average learning outcome score was 73. This score increased to an average of 80.5 in the first cycle and showed a significant improvement to 86 in the second cycle. Based on these findings, the STAD cooperative learning model assisted by Wordwall media can serve as an effective solution to enhance student participation and create an enjoyable learning environment during the learning process, thereby improving learning outcomes.

Abstract

This study aims to analyze the chemical representation abilities of students at the macroscopic, submicroscopic, and symbolic levels in acid-base material practicums in class XI Science of SMAN 2 Mataram. The type of research is descriptive quantitative. The study population was 288 students of class XI SMAN 2 Mataram. The research sample was selected using purposive sampling technique obtained by class XI Science 7 students totaling 36 students and class XI Science 8 students totaling 36 students. Data collection techniques used interview, observation, documentation, and test instruments. Data analysis used N-gain percentage. The results showed that students' initial chemical representation abilities were relatively low, with an average pretest of 34.50% (macroscopic), 31.00% (submicroscopic), and 35.00% (symbolic). After the lab-based learning, posttest results showed significant improvements at all levels of representation, namely 85.25% (macroscopic), 78.25% (submicroscopic), and 76.50% (symbolic). The average total improvement increased from 33.50% to 79.99%, and is considered good. These results indicate that the chemistry lab is effective in improving students' representational skills on acid-base material.
