Abstract

This study aims to improve students’ learning outcomes in thermochemistry through the implementation of Wordwall-based game learning media using the Teams Games Tournament (TGT) cooperative model. This research employed a Classroom Action Research (CAR) approach conducted in two cycles, each consisting of planning, action, observation, and reflection stages. The subjects of this study were 35 students of class XI-3 at SMA Negeri 10 Medan. The research instruments included learning outcome tests (pre-test and post-test), observation sheets, and student worksheets. Data were analyzed using descriptive quantitative methods with the N-gain test to determine the improvement in students’ learning outcomes. The results showed a significant improvement in learning outcomes from cycle I to cycle II. The percentage of learning completeness increased from 51.4% in cycle I to 94.3% in cycle II. The N-gain analysis also indicated an increase in students’ learning achievement categories. Therefore, it can be concluded that the implementation of Wordwall-based learning media through the TGT model is effective in improving students’ learning outcomes in thermochemistry.

Abstract

Chemistry education on colloid systems presents persistent challenges due to the abstract and submicroscopic nature of the concepts involved, which conventional instructional methods struggle to address effectively. This study aimed to develop Augmented Reality (AR)-based chemistry learning media integrated with local wisdom for colloid system instruction, evaluate its validity and practicality, and measure its effectiveness in reducing misconceptions and improving students' learning outcomes. Using the ADDIE development model with a one-group pretest-posttest design, the study was conducted at SMA Swasta Methodist 7 Medan involving 26 students of class XI IPA. The developed media consisted of two AR marker-based learning tools: AR Link 1 covering dispersed substances, dispersion media, and colloid types contextualized through local cultural examples such as gulai and teh talua, and AR Link 2 visualizing colloid properties including Brownian motion, the Tyndall effect, coagulation, dialysis, adsorption, and electrophoresis through animated microscopic representations. Validation results showed average scores of 4.4 (content) and 4.3 (language) categorized as valid, and a perfect score of 5 (very valid) across all media aspects. The instrument validation reached 93.1%, categorized as highly feasible. Student learning interest ranged from good to very good (74.04%–80%), and observation data confirmed active participation (75%–95%). The N-gain score of 0.64 indicated moderate improvement in conceptual understanding, while posttest results demonstrated substantial reduction of misconceptions across all colloid concepts. The AR-based media integrated with local wisdom was concluded to be valid, practical, and effective for colloid system learning.
