Enhancing Chemistry Achievement through Decryption Game-Based Learning Management for Grade 12 Students

Abstract

        The objective of this research is to compare the learning outcomes in Chemistry, specifically on the topic of Organic Compounds, using a game-based learning approach. The sample for this study comprises 41 students from the Science and Mathematics Program in Grade 12/9 at Attarakiah Islamiah School during the 2023 academic year. The selection method used was purposive sampling. Data collection tools included: 1) six lesson plans incorporating a decryption game, 2) a learning achievement test on Organic Chemistry. The lesson plans were validated and the learning achievement test on Organic Chemistry. Data analysis utilized statistical measures including mean, standard deviation, and Relative Gain Score.

      The research findings reveal that the post-learning outcomes in Chemistry, specifically in Organic Compounds, after implementing the game-based learning approach, were significantly higher than the pre-learning outcomes among Grade 12/9 students at Attarkiah Islamiah School. The statistical significance level was set at 0.05. The average Relative Gain Score (Y-X) for the sample group of 41 students was 5.10, indicating a substantial improvement. The average development score was 26.22, which falls within the moderate level of development.
