{"abstract":"This descriptive-exploratory study, conducted in the 2023–2024 academic year, determined the extent of difficulties English language studies majors at Mindanao State University-Sulu encountered during their language learning experience. Employing Pearson's r correlation test, the weighted mean, standard deviation, t-test for independent samples, and one-way ANOVA, the study involved 100 respondents, predominantly female, in their first or second year of college, and aged 20 or older. Students reported a “Moderate” level of difficulty in both grammar and pronunciation, indicating these are not major obstacles but present a balanced challenge. The degree of difficulty in learning English was almost always the same across age and gender-based groups, but a discernible difference emerged when statistics were sorted by year level. A significant relationship was found between subcategories of English learning difficulties, suggesting that struggles with pronunciation can correlate with difficulties in reading written words and overall reading comprehension. Similarly, grammar difficulties may hinder comprehension of sentence structure and meaning in written texts.","abstract_source":"gemini_shortened","authors":["Rosana Yusop"],"date":"2024-06-03","doi":"10.5281/zenodo.11452011","id":2994,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"920bd0b116721292d38b28b58dc9b307eb36753b4ede0a5fb7adadf4cfb28b23","schema":"scimatic-article/1","title":"Difficulties in Learning English Language Among Bachelor of Arts in English Language Studies Students at Mindanao State University-Sulu","volume":20}
