This document summarizes a study on error analysis of highly motivated students in target language speaking and writing at the secondary level. The study aims to identify whether native language transfer is a major cause of errors in the target language of English. Samples of written assignments from 60 students in their first and second academic years were collected on topics and analyzed for errors. The study found that errors in writing mainly occurred due to interference from the native language, overgeneralization of rules, and faulty teaching materials. Errors in speaking were often due to the influence of the native language's phonology. To reduce errors, a direct teaching method ignoring the native language is recommended, along with awareness among teachers and students of factors influencing foreign language learning.
