First and foremost, I am profoundly thankful to my supervisor, Dr. Nguyen Tien Phung, for the thoughtful guidance, critical comments, and precious advice that he broadened my horizon in this field. Without his great patience and constant encouragement during the process of conducting this study, the work would never have been completed. I feel fortunate to have had his support for my work.
Secondly, I would like to express my sincere gratitude to all of the professors and doctors, not only at Quy Nhon University but also at other universities, for imparting knowledge to me regarding both general and specialized subjects which enabled me to have a strong theoretical foundation and created the ideal environment for my study. This study was made achievable by the presence of the enthusiastic children and their parents at two kindergartens in Quy Nhon city, who devoted their time taking part in this research. I was also thankful to all the teachers at the kindergartens for their fascinating assistance, support, and management during the process. I am very lucky to know all of them.
Last but not least, I would like to express my sincerity to my beloved family and friends. They have always supported me and given me the strength to go through all the difficulties I encountered when I carried out this research. Quy Nhon, October 2023 iii ABSTRACT This study aimed to examine the impact of the Digital Homework Activities (DHA) on vocabulary learning of children. In addition, it sought to find out how pupils and their parents felt about learning English vocabulary through the DHA app.
To achieve the goal, the study was carried out with the participation of 120 five-year-old children in two kindergartens in Quy Nhon City. These participants were divided into two groups, namely control group and experimental group. Three research instruments were employed including a vocabulary test, a questionnaire, and an interview. The data were collected using mixed method: the quantitative data were obtained from a pre-test and post-test on vocabulary whereas the qualitative ones were from a questionnaire and an interview.
The collected data were analyzed in terms of descriptive statistics with the use of SPSS. The findings suggested that both vocabulary learning and vocabulary retention among the control group and the experimental one improved after eight weeks. However, the post-test of the experimental group increased significantly compared to the control group. Additionally, most participants held positive attitudes toward learning and improving their vocabulary retention via the DHA app.
Based on such findings, the researcher proposed several implications focusing on the teaching and learning of English vocabulary for children. iv TABLE OF CONTENTS STATEMENT OF AUTHORSHIP. iii TABLE OF CONTENTS.
