A SURVEY ON BLENDED LEARNING MODEL USING AN AI-INTEGRATED MOBILE APPLICATION TO ENHANCE WRITING SKILLS FOR EFL FRESHMEN IN MEKONG DELTA, VIETNAM

Abstract

In the context of 4.0 industrial revolution, mobile learning (M-learning) has emerged as a flexible educational solution, supporting students to study anytime, anywhere. This study was conducted to address the challenges in writing skills (from grammar, vocabulary to structure) that first-year non-English major students in Vietnam often encounter. The paper proposes a blended learning model, using AI-integrated mobile applications such as ChatGPT, Grammarly to provide instant support and additional practice opportunities outside of class time. Based on the TAM 2 of Venkatesh and Davis (2000), a quantitative survey with ninty-eight (98) students at a university in the Southwest region was conducted to assess the model's perceived usefulness (PU) and perceived ease of use (PEOU). The results of SPSS 20 analysis showed positive attitudes from learners, who appreciated the immediate feedback and convenience of mobile devices. However, the study also acknowledged some limitations, including the small sample size and the focus on non-major students, which may reduce the representativeness and generalizability of the results. The paper concludes with specific implementation proposals and future research directions, affirming the strong application potential of this model in the future.
