Effectiveness of Game-Based Lessons in Improving the Performance of Grade 8 Students in Chemistry

This study determined the effectiveness of game-based lessons in Chemistry to improve the academic performance of Grade 8 students at Buhang National High School, Division of Sorsogon Province for the academic year 2022-2023. The study utilized the developmental method of research and involved 30 Grade 8 Einstein students who were randomly selected, and 5 science teachers as evaluators who were purposively selected. The study intended to answer three research questions: (1) What game-based lessons may be developed along specific topics in Chemistry? (2) What is the validity of the developed game-based lessons based on DepEd LRMDS in terms of content, format, mechanics, and accuracy? (3) How effective is game-based learning in improving the academic performance of students in Chemistry? The statistical tools employed in the study included the calculation of weighted means, frequency distributions, and the use of t-tests for dependent samples to analyze the data. The findings revealed that six game-based lessons in Chemistry were developed using the 7E's model, which are (1) Particle Nature of Matter, (2) Properties of Matter, (3) Phase Changes in Matter, (4) Structure of Atom (5) Atomic Symbols, and (6) Trends in the Periodic Table. The game-based lessons were found to be valid based on DepEd LRMDS, specifically in terms of content, format, mechanics, and accuracy. Furthermore, the developed game-based lessons were found to significantly enhance the academic performance of students, as reflected by their post-test scores. The study recommended that science educators should further improve the developed game-based lessons by incorporating a variety of game elements and integrating localized and contextualized game materials, in order to enhance students' engagement and learning outcomes. Moreover, the games used in every classroom setting can be modified constantly to meet the needs of different learners and develop the desired competencies. Science educators are encouraged to utilize game-based learning as a means to enhance their students' academic performance and attain higher levels of achievement.
