Abstract

This study presents a comprehensive content analysis of punctuation and capitalization errors in Facebook posts made by Junior High School students aged 13 to 17 at Immaculate Conception College of Balayan, Inc. Data was collected from various types of posts, including personal updates, shared articles, and public comments. Employing quantitative methods, particularly Pearson Chi-Square tests, the analysis assessed the frequency of these errors and examined potential correlations between error types and student demographics. The findings revealed that punctuation errors, particularly involving commas and periods, were the most prevalent, followed by capitalization mistakes related to proper nouns and the beginning of sentences. Notably, no significant correlations were found between the frequency of errors and demographic factors such as age, sex, grade level, or duration of Facebook usage. Based on these results, the study recommends that educators implement targeted grammar lessons and increase writing exercises to address these common errors. Furthermore, it suggests that future research explore additional variables influencing grammar usage, the impact of social media on writing practices, and the broader implications of these findings. This research highlights the linguistic challenges faced by junior high school students in a social media context and provides practical recommendations for enhancing students’ writing skills.
