Abstract
One issue international students may encounter is the use of regional dialects in specialized university lectures. To explore effective ways to support their understanding, this study analyzes three chemistry-related lectures to examine how the Kansai dialect is used. We extracted sentences containing dialectal features, annotated their contextual functions, and categorized them based on functional similarity. The results suggest that while the overall presence of dialectal expressions is limited and unlikely to significantly hinder comprehension, certain utterances play a key role—for example, in understanding lecture structure, gaining deeper insights into the underlying principles and intuitions behind chemical phenomena, and following professors’ instructions or responses to student questions.
