- Are there any improvements in the listening comprehension ability of the learners? - What are the obstacles that the students may encounter while using completion dictation techniques? 1.4 Significance of the research The research is critical for improving listening skills in learning English Based on the findings of the study, advantages can be acquired as below: - To students: For those who have not known about the completion dictation technique, the results of the study will furnish the learners with some information on this technique and students can apply the completion dictation technique in their improvement of listening skills Moreover, students who have known this technique beforehand would adjust their learning methods to enhance listening skills more effectively due to the perspective they have on the benefits and limitations of the completion dictation techniques - To teachers: Data produced from the research will inform the teachers about the learners’ attitudes towards completion dictation technique and their common obstacles This empowers the teachers to apply appropriate teaching methods, create interesting activities so that the students can acquire the knowledge productively - To further researchers: This research can be a helpful reference for researchers in the future It will assist them with revealing crucial spheres related to this issue that many researchers could not investigate Supervisor: Ho Thi Hien, M.A Submitted by Nguyen Hoang My My ID number: 17035321 1.5 Scope of the research There is a limited number of participants since the study is conducted only in the context of the Industrial University of Ho Chi Minh City The research focuses on a group of 121 Englishmajored students from the Faculty of Foreign Languages Next, the research only concentrates on the relationship between listening comprehension and the completion dictation techniques so the thesis will not specify any resolution for the given issues Last, the results which show the improvements of the participants will be compared only between pretest and post-test results Supervisor: Ho Thi Hien, M.A Submitted by Nguyen Hoang My My 27/1/2021 – 4/2/2021 1/3/2021 – 8/3/2021 17/3/2021 – 15 - Approve chapter - Start to write chapter ………continue 25/3/2021 – - Upload completion dictation 1/4/2021 - Correct and approve chapter 2/4/2021 – 10/4/202118/4/2021 – - Upload completion dictation - Upload completion dictation - Upload completion dictation - Prepare the post-test 26/4/2021 – - Upload completion dictation 10 3/5/2021 - Correct and approve the post-test 4/5/2021 – - Conduct the post-test 11/5/2021 - Prepare and approve questionnaire 12/5/2021 – 19/5/2021 16 - Upload completion dictation - Continue or not?
