Grammatical Errors in Students' Descriptive Writing and Implications for English Language Teaching

Abstract

Writing descriptive texts requires students to express ideas accurately and apply appropriate grammatical rules. However, grammatical errors remain a common problem among EFL learners, particularly at the junior high school level. Although previous studies have examined grammatical errors in descriptive writing, limited attention has been given to how specific error patterns can inform grammar instruction. This study aimed to identify grammatical errors in students’ descriptive writing, determine the dominant error type, and examine their implications for English teaching. A descriptive qualitative design using error analysis was employed. The participants were 30 seventh-grade students of SMP Negeri 18 Surakarta. Data were collected from two descriptive writing tasks, My Best Friend and My Favorite Teacher, supported by interviews. The analysis identified 167 grammatical errors, of which 73.1% were omission errors and 26.9% were misformation errors, while no addition or misordering errors were found. The predominance of omission errors indicates that students particularly needed support in recognizing and producing required grammatical elements in descriptive sentences. These findings are significant for EFL teachers because they provide an evidence-based basis for prioritizing explicit instruction on frequently omitted grammatical elements, contextualized writing practice, and continuous corrective feedback. Addressing these patterns may help teachers target students’ specific grammatical difficulties rather than relying on general grammar instruction.
