Analysis of Grammatical Errors in Narrative Texts of English Lessons for Grade XI of Purworejo State Islamic Senior High School in the 2024/2025 Academic Year

Narrative text is an important part of English learning, especially at the Madrasah Aliyah level. In this context, the analysis of grammatical errors in narrative texts aims to identify errors that are often made by students and how they affect the quality of their writing. In general, grammatical errors in narrative texts at the high school level involve various aspects, such as the use of tenses, verbs, sentence structures, and prepositions. These errors can occur due to students' lack of understanding of correct grammar rules, carelessness when writing, or direct translation from Indonesian to English without considering the structural differences between the two languages. Literature studies show that errors in the use of tenses are often the main problem in writing narrative texts. In addition, the use of inappropriate compound sentences, as well as errors in the use of articles and prepositions are also often found. Several studies have revealed that the main factor causing these errors is the influence of the mother's tongue, namely Indonesian, which has a very different grammatical structure from English. In addition, inadequate teaching and training factors in the classroom also affect students' ability to apply correct grammar rules in narrative texts. For this reason, the analysis of grammatical errors in this narrative text is expected to provide insight for teachers and students in improving their English language skills, especially in writing grammatically correct narrative texts.
