Visualized Diagnostic Assessment Data for Syllabus Design in English as Foreign Language: A Model for Enhancing Language Learning Needs in Higher Education

Data visualization has empowered analyzing, exploring, and communicating data effectively. It has been widely adopted across diverse disciplines. However, research indicates that data visualization in education is mainly favored in distance learning environments, leaving traditional classroom settings largely unexplored. Moreover, despite the growing emphasis on data-driven decision-making in education, a notable gap exists in using visualized assessment data to develop curriculum planning in language classrooms. Therefore, we developed a model for syllabus design and material development in an EFL classroom in Taiwan based on diagnostic test results. An online adaptive diagnostic test was used to gather visualized assessment data, which was analyzed with an AI tool to identify language learning needs and to develop the syllabus design and materials. By incorporating visualized diagnostic assessment data into the decision-making process, educators can design responsive and individualized syllabi that meet the needs of students. This approach enhances the effectiveness of language teaching and makes curriculum development more accessible and manageable for educators.
