{"abstract":"The study aimed to assess the impact of YouTube Tutorials as a classroom reinforcement tool on Grade 7 students' English Language Proficiency during the 2022-2023 academic year. It sought answers to questions regarding students' language proficiency levels before and after watching YouTube Tutorials in morphology, phonology, semantics, and syntax, as well as the overall improvement in English competence. The study employed a mixed-method research approach with 54 respondents, utilizing a self-made survey questionnaire.The findings revealed that students initially had fair to poor proficiency levels in various language areas, which significantly improved after exposure to YouTube Tutorials. The mean differences demonstrated a substantial increase in English competence, with a p-value of 0.000*, indicating statistical significance. YouTube Tutorials were found to reinforce learning by enhancing comprehension, problem-solving, and advanced study. It also contributed to broader knowledge acquisition, creativity, and improved language skills. In conclusion, YouTube Tutorials proved effective in enhancing English language proficiency among Grade 7 students. Recommendations included considering YouTube Tutorials as a reinforcement tool for English teachers, providing classroom technology, encouraging parental support, and emphasizing the importance of quality video content. Further research in different contexts and with diverse respondents was suggested for result validation.","abstract_source":"original","authors":["Apritch Honey Cinco","Arnel Pradia","Leonel Untong"],"date":"2023-10-20","doi":"10.5281/zenodo.10025259","id":2135,"issue":6,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"240182aba84d8e56ccc2e0c8bae4b3fa7d7d35f6c86d9a0b8ee0f09232358f36","schema":"scimatic-article/1","title":"YouTube Tutorials: A Classroom Reinforcement to the Students’ English Language Proficiency","volume":14}
