Abstract

Thermochemistry is one of the chemistry topics that students often find difficult because it involves abstract concepts and mathematical calculations, resulting in low learning outcomes and limited classroom participation. This study aimed to improve students’ learning outcomes and learning activities through the implementation of the Teams Games Tournament (TGT) learning model assisted by Wordwall media in thermochemistry learning. The study employed Classroom Action Research (CAR) using the Kemmis and McTaggart model, consisting of two cycles: planning, action, observation, and reflection. The research was conducted in class XI-F1 of MAN 2 Model Medan during the 2025/2026 academic year, involving 35 students. Data were collected through achievement tests, observation sheets, and documentation. The results showed that the implementation of the TGT learning model assisted by Wordwall media improved students’ learning outcomes and learning activities. The average posttest score increased from 69.29 in Cycle I to 91.71 in Cycle II. Furthermore, the average N-gain score increased from 0.35 (medium category) to 0.87 (high category). Students’ learning activities also improved from 64% in Cycle I to 82% in Cycle II. These findings indicate that the integration of the TGT learning model and Wordwall media is effective in enhancing students’ understanding of thermochemistry concepts and encouraging active participation in the learning process.

Abstract

The Socio-Scientific Issues (SSI) approach is a learning strategy based on social issues related to science, which aims to improve students' scientific literacy and critical thinking skills. And this approach is able to improve students' scientific literacy and social awareness by connecting chemical concepts to real-world social challenges. This literature review examines the effectiveness of SSI-based learning in improving critical thinking, argumentation skills, and contextual understanding among students. The research method used is a literature review using 10 journals as findings showing that SSI encourages deeper engagement by connecting chemistry to issues such as environmental pollution, industrial waste, and sustainable development, making learning more relevant and meaningful. However, challenges such as limited teacher familiarity with SSI integration, curriculum constraints, and students' difficulties in analyzing complex socio- scientific debates hinder its widespread implementation. Proposed solutions include teacher training programs, adoption of problem-based and inquiry-based learning models, and institutional support for curriculum development. The study concludes that SSI significantly improves scientific literacy and decision-making skills when supported by structured pedagogical strategies and institutional commitment. Future research should focus on a scalable SSI implementation framework and its long-term impact on students' social and scientific competencies.
