Effectiveness of Online Distance Learning Delivery Modality among High School Learners in Mathematics 9

Abstract: This study examines the effectiveness of Online Distance Learning (ODL) in enhancing the academic performance of Grade 9 learners in Mathematics at Gadsden County High School, Florida, USA, during the 3rd quarter of the 2020–2021 school year. With the shift from traditional learning to online modalities due to the COVID-19 pandemic, this research evaluates how ODL impacts students' mastery of mathematical concepts, focusing on linear equations, systems of linear equations, and exponential functions. A pre-post experimental research design was employed, with 13 purposively selected learners participating in the study. The learners were given a 35-item pre-test before exposure to the ODL modality and a post-test after completing the instructional period. The results showed a significant improvement in mean test scores, increasing from 7.23 (20.66%) in the pre-test to 22.38 (63.94%) in the post-test, with a computed t-value of 16.37, indicating statistical significance. These findings highlight the potential of ODL to enhance mathematical skills through interactive online materials and collaborative learning approaches. The study affirms that the use of digital tools fosters student engagement and improves performance, particularly for students who may struggle in traditional classroom settings. This research underscores the importance of leveraging technology to create a flexible and inclusive learning environment. The results suggest that ODL can be an effective alternative for teaching mathematics, ensuring continuous learning amidst physical restrictions. Recommendations for further studies include expanding the sample size and exploring other subjects to assess the broader impact of ODL on academic performance.
