Canva-Assisted Instruction in Teaching Visible Light Color Energy

Aim: This study aimed to assess the effectiveness of Canva-assisted instruction in improving Grade 12 students' conceptual understanding of Visible Light Color Energy.Specifically, it sought to determine the students' pre-test and post-test scores, assess significant differences within and across groups, and develop an enhanced lesson plan using Canva-integrated strategies under the 7Es instructional model.Methodology: A quasi-experimental design with nonequivalent groups was employed involving 100 Grade 12 students-25 in the control group and 75 in three experimental groups.The control group received traditional instruction, while the experimental groups were taught using Canva-assisted materials with varied visual and interactive designs.A validated 30-item test (KR-20 = 0.762) measured conceptual understanding before and after the intervention.Data were analyzed using descriptive statistics, Shapiro-Wilk, Kruskal-Wallis, and Mann-Whitney U tests. Results:The post-test results revealed that all experimental groups outperformed the control group, with statistically significant differences (p < 0.05).Among the experimental groups, Canva-assisted instruction incorporating interactive and visual learning tools led to higher levels of conceptual understanding in visible light color energy.The findings confirmed that integrating Canva in science instruction enhances student engagement, comprehension, and performance.Conclusion: Canva-assisted instruction significantly improves students' conceptual understanding of abstract Physics topics such as Visible Light Color Energy.The developed lesson plan offers a practical, scalable, and engaging instructional model that aligns with curriculum standards and supports student-centered learning.
