Abstract

This research aims to determine the influence of the Read, Answer, Discuss, Explain, and Create (RADEC) model on the chemical literacy abilities of class XI students at SMA Negeri 7 Lhokseumawe through aspects of chemical literacy, namely aspects of context, knowledge, and competence. This research is Pre-Experimental Design research, carried out in the odd semester of the 2023/2024 academic year at SMA Negeri 7 Lhokseumawe. The subjects in this study consisted of 2 classes that took cross-interest chemistry lessons, namely classes XI-1 and XI-2, with 55 students. Sampling was carried out by purposive sampling. The data collection techniques and instruments used in this research were essay questions in the form of stories or literacy, totaling nine questions about reaction rate. The research results show that the t-test data on students' chemical literacy test learning outcomes has a sig. value. (2-tailed) 0.000 0.05, so H0 is rejected, and Ha is accepted. The conclusion is that the RADEC learning model influences the scientific literacy abilities of class XI students at SMAN 7 Lhokseumawe on the reaction rate material. The average value of the students' chemical literacy aspects is that the average value of the context aspect in the experimental class is 79.01, the knowledge aspect is 87.65, and the competency aspect is 60.49. The average value of the context aspect in the control class is 69.04, the knowledge aspect is 35.11, and the competency aspect is 45.83. The influence of chemical literacy abilities can be seen from the average value of students who use the RADEC learning model 76, with the good criterion being higher than students who use the conventional learning model, which is 50 with sufficient criteria.

Abstract

The integration of Augmented Reality (AR) technology into educational media has the potential to enhance student engagement and understanding of abstract concepts. This study aimed to develop and evaluate the quality of AR-integrated learning media for teaching molecular structures in chemistry. Using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model, this research employed a systematic approach that encompassed five stages of development. The study was conducted with two eleventh-grade classes at a public high school (SMA Negeri 1 Lhokseumawe), involving 66 students as the subjects of the research. Expert validation of the developed media yielded a score of 88, which categorizes it as "Excellent." At the same time, student feedback on usability and engagement resulted in a score of 4.77 in the same category. These results indicate that the AR media is effective and well-received as a supplementary tool for learning molecular structures. The findings highlight the potential of AR technology to enhance conceptual understanding and improve learner satisfaction in the field of chemistry education. Future studies should explore its application across other topics and educational levels to further validate its efficacy and scalability.
