Abstract
The study investigated the Subject-Verb Agreement (SVA) errors committed by third-year students of Negros Oriental State University (NORSU) found in the students' reflective comments on Dr. Craig Refugio's YouTube Channel. Screenshots of the Ed 303 (Methods of Research) sections D and F comments were taken, and content analysis was done to identify the number of SVA errors committed by the students in their written outputs. Additionally, an interview with the participants took place to determine the reasons for their errors. The study revealed that most third-year students in ED303 Sections D and F classes had committed SVA errors. A significant percentage of them were females and Filipino majors who came from public high schools. These students committed SVA errors because of their lack of foundational knowledge, confusion about the SVA rules, absence of comprehensive knowledge of SVA, failure to review and proofread the written outputs because of time constraints, and their first language preference over the second language. Hence, an awareness program of SVA-related activities, collaboration with the university English club, and free access to Grammarly software and other grammar checker tools are recommended to help resolve the problem.
