10. Summary of the thesis results:

This thesis summarizes the theoretical research directions on fixed word combinations (collocations) in English by international scholars, thereby determining the theoretical basis of the thesis. The thesis uses a combination of error analysis and corpus linguistics to survey more than 130 written products (over 66,828 words) of 3rd and 4th year students of the English Pedagogy Department, University of Foreign Languages, Vietnam National University, Hanoi. The analysis results show that, (1) considering fixed word combinations from a grammatical perspective, errors in fixed word combinations are concentrated mainly in confusion between noun and preposition combinations (“about, on, for”), (2) considering fixed word combinations from a lexical perspective, errors are concentrated in two subtypes: nouns combined with adjectives and verbs combined with nouns. The cause of the errors is predicted to be due to the negative linguistic transfer of Vietnamese to English, causing confusion in meaning. Furthermore, at a higher level, students tend to rephrase words; however, choosing synonyms may not be appropriate in some cases.

11. Practical applicability: Based on these results, the pedagogical conclusion recommends that learners and teachers make adjustments focusing on some common errors as indicated in the study.

12. Future research directions: research combining fixed vocabulary used by Vietnamese students in general, with a particular focus on a wider range of proficiency levels.

10. Summary of the findings of the thesis:

The thesis provides a theoretical basis of English collocations with the definitions and classifications under many perspectives of world scholars. The error analysis associated with the method of corpus linguistics is employed to investigate in more than 130 writing products of 3rd and 4th year students in Faculty of English Teacher Training and Education, University of Languages ​​and International Studies, VNU. After analysis, the results show that collocational errors occur in the essays, especially in collocations of noun and preposition "about, on, for” in grammatical collocation group. In lexical collocations, errors are identified in two sub-categories of Nouns - Adjectives and Verbs - Nouns. The main predicted reason is the negative language transfer of Vietnamese into English, causing confusion about meaning. In addition, at a high level, students tend to paraphrase in writing, however, in some cases make wrong word choices.

11. Practical applicability: Based on these results, pedagogical implications suggest that learners and teachers should focus on those main errors which are shown in the study.

12. Further research directions: Collocations used by students of multi levels in English.
