A Training of Harnessing  Generative AI in Designing a Deep Learning-Based English Lesson Plan for EFL Vocational Teachers

The rapid advancement of generative artificial intelligence (Gen-AI) has opened new opportunities for English language teaching, particularly in designing lesson plans grounded in deep learning approaches. However, many EFL teachers still lack adequate training to use these tools effectively. This study investigated vocational high school EFL teachers' perceptions of Gen-AI training and the challenges they encountered. The participants were 52 EFL teachers from public and private schools who took part in a community service program. Data were collected through a questionnaire, including open-ended items, and analysed using descriptive statistics. The results showed positive perceptions of the training. Most teachers agreed that Gen-AI is relevant to their professional development, supports creativity in lesson planning, and speeds up the preparation of deep learning-based materials. They also reported confidence in using Gen-AI responsibly and strong motivation to continue applying it in their classrooms. Nevertheless, challenges remained in digital literacy, technical expertise, and the adaptation of Gen-AI outputs to classroom contexts. These findings point to the need for sustained professional development, institutional support, and further research on the long-term impact of Gen-AI.
