The purposes of the present study were to examine the language errors in a writing of English major students in a Thai university and to explore the sources of the errors. This study focused mainly on sentences because the researcher found that errors in Thai EFL students' sentence construction may lead to miscommunication. 104 pieces of writing written by 26 second-year English major students who enrolled in the Writing II course were collected and analyzed. Results showed that the most frequently committed errors were punctuation, articles, subject-verb agreement, spelling, capitalization, and fragment, respectively. Interlingual interference, intralingual interference, limited knowledge of English grammar and vocabulary, and carelessness of the students were found to be the major sources of the errors. It is suggested that intensive knowledge of English grammar and vocabulary be taught to Thai EFL students. Moreover, the negative transfer of students' first language should be taken into account in English writing classes. This finding also implies that explicit feedback on students' writing errors is genuinely needed.

This paper aims to provide information about teacher corrective feedback that would be helpful for EFL students’ writing improvement. It focuses on feedback provided to correct grammatical errors made by student writers as the author finds that this type of errors can obstruct the effectiveness of students’ pieces of writing and may result in written miscommunication. Both direct and indirect teacher feedback types are discussed. Some pedagogical suggestions have been made based on the findings. It is hoped that this review article can help teachers and students in a writing class achieve the goal of producing grammatically correct English writing assignments.

Games have been widely accepted as an effective tool for language learning. They help learners achieve better learning outcome and create a learning atmosphere which contribute to learners’ learning. The present study, hence, employed games to help EFL learners write better in English. In the present study, games were used to encourage Thai EFL learners to self-correct errors found in their English sentences. After five weeks of learning with games, the learners’ ability to self-correct errors was observed. Their posttest average score (x =18.65, S.D.=6.05) was higher than the pretest one (x =13.58, S.D.=6.45). The results from the paired samples t-test indicated a statistically significant difference at the 0.01 level which meant that games helped promote this group of learners to self-correct errors in written English sentences. Furthermore, the learners reported that they enjoyed English writing classes with games because they motivated them to learn English in a relaxing class. The learners’ good interaction and collaboration were also observed during the games. The findings from this study imply that games should be incorporated in language classes for learners’ positive learning outcome.
