AI for curriculum design in language learning classes has become a polarizing topic since ChatGPT was released. One the one hand, AI can provide personalized learning experiences for students based on their individual needs, which can improve learning outcomes. It can also help teachers save time by automating tasks such as grading and providing feedback. However, there are also concerns about the use of AI in education, such as the potential for bias in the algorithms used by AI systems, which can perpetuate existing inequalities in education. A further concern is the potential for overreliance on AI, which could lead to a reduction in the role of teachers and human interaction in the classroom. Additionally, the use of AI for curriculum design raises ethical questions. This presentation will present the results of survey and interview qualitative based research of Japanese university English language teachers into the use of AI in language learning curriculum design. Results will demonstrate that although there are concerns about its use, teachers are overwhelmingly in favor of using AI for curriculum design. This presentation will conclude with a discussion on the reasons why language teachers should embrace this technology and use it to their advantage.
