The researchers are interested in finding out the correlation of online learning and academic achievement of First Year Bachelor of Secondary Education (BSEd) Major in English of Mindoro State University (MinSU), specifically the students’ level of performance of students in online learning in terms of: quizzes, major examinations, performance tasks, and recitation. The data revealed that the level of writing skills of first year BSED Majors who used the pen-and-paper method in terms of spelling, vocabulary, and sentence structure was high, all with average scores of 11. On the other hand, the results showed that the level of writing skills of first year BSED Majors who used Microsoft Teams was very high in terms of spelling, with an average score of 14, and high in terms of vocabulary and sentence structure, with both average scores of 12. The computed p-value between the Microsoft Teams spelling and pen-and-paper method spelling was 0.001. In terms of Microsoft Teams vocabulary and pen-and-paper method vocabulary, the p-value was 0.004. Lastly, the computed pvalue between the Microsoft Teams sentence structure and pen-and-paper method sentence structure was 0.002. Based on the results, the computed p values of the three variables were less than the critical value at the 0.05 level of significance. Therefore, the null hypothesis of no significant difference was rejected. The findings revealed that there was a significant difference in the level of writing skills between first year BSED Majors who used the pen-andpaper method and those who used Microsoft Teams in terms of spelling, vocabulary, and sentence structure.
