A Study on English Collocation Errors of Thai EFL Students

Collocation is an often-neglected language form that foreign language teachers and students should focus on to achieve competence in a target language. In this research, the researchers studied purposely to facilitate both second language teachers and students to produce correct and appropriate collocations. The purposes of this research were 1) to study the collocation error levels of Bachelor of Arts English and Business English students studying at Northern Rajabhat University, 2) to study the relationship between first language (L1) and second language (L2) transfer collocation errors in students writing, and 3) to compare the collocation errors between high-proficiency students, medium- proficiency students and low-proficiency students. The research sample included 285 Thai EFL students enrolled in second-year English and Business English programs at Northern Rajabhat University during the first semester of the academic year 2021. The research instrument was a collocation proficiency test with 54 questions, which was divided into 2 sections: 1) 36 questions with 4 multiple-choice tests, and 2) 18 Thai to English translation questions. The items were chosen from the Oxford 3000, and were common vocabulary appearing in various contexts. Research data were analyzed using mean, standard deviation, t-test (Dependent), and Friedman test. The research found that 1) the level of Grammatical Collocation errors of high-proficiency EFL students was at a moderate level, medium-proficiency and low-proficiency EFL students were at a high level, and for Lexical Collocation errors, all three groups of students were at a high level; 2) the EFL studentscollocation errors were caused by the language transfer from their first language (L1) to their second language (L2), synonyms, and lack of collocation competency; and 3) the most Lexical Collocation errors found in all student groups were Adverb + Adjective. For Grammatical Collocation, all groups could use Verb + Preposition better than Noun + Preposition, and the high proficiency and medium proficiency students could perform Adjective + Preposition the least, whilst the low proficiency students were better at Adjective + Preposition.
