Abstract
This research assessed the academic achievements of Senior High School students from National University – Dasmariñas (NU Dasmariñas) in relation to online and face-to-face classes. Three hundred thirty-six (336) students took part in the study, and data was obtained from students’ academic records which included the Grade 10 grades of the current Grade 11 students, the Grade 11 grades of the current Grade 12 students, as well as Term 1 marks of both grades. The study employed a descriptive correlational research framework and applied several statistical analyses which included t-tests, ANOVA, and regression analysis. The study uncovered that the students’ performances differed according to the learning modalities used with t = 5.295, p < 0.001 indicating that students who participated in face-to-face classes performed better than those who learnt online, especially in Grade 12. Students in the sample had a mean age of 16.54 years. Female students (n= 209) also outperformed their male counterparts (n = 127) across both learning modes (F = 2.802, p < 0.001 for online; F = 1.614, p = 0.009 for face-to-face). Furthermore, the study highlighted performance differences across strands where ABM students performed the highest (F = 2.171, p < 0.001). Finally, there were no differences across grade levels. This study shed light on the effectiveness of online learning. However, in-person teaching is best for achieving higher academic outcomes—particularly for older students and female students—important for developing educational policy frameworks for the post- COVID-19 period.
