{"abstract":"The purpose of the study was to explore the multifaceted challenges faced by junior high school students in learning English as a second language in a private educational institution. The respondents' profiles were examined as well as the challenges they encountered in learning English in terms of grammar, vocabulary, pronunciation, sentence structure, and the four macro skills: listening, speaking, reading, and writing. To reach the researchers’ aim, a survey was conducted among 80 students using a survey questionnaire made by the researcher which was formatted using the Likert Scale. The findings revealed that students were greatly challenged with vocabulary acquisition and least challenged with pronunciation. There were no significant differences in challenges based on sex, age, and the way of utilizing the English language at home, but grade level and socioeconomic background did influence reported challenges. The study recommends needs assessments, professional development for teachers, and creating an English-rich environment at home.","abstract_source":"original","authors":["Nico James Urlanda","Gloria Ching","Melchor Espiritu","Celerina Oreta"],"date":"2025-03-21","doi":"10.70838/pemj.340108","id":4722,"issue":1,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"1084a02d8f64fd01562b9fe0fd7fe4ad019a5dcc54efde56e450d79635e36d5a","schema":"scimatic-article/1","title":"Exploring the Multifaceted Challenges of Learning English as a Second Language in a Private Educational Institution in Gumaca, Quezon","volume":34}
