Teaching styles in science and engineering instruction were compared by analysing corpora of transcripts of lectures delivered in English and Japanese at leading universities in the United States and Japan, respectively. Our findings were compatible with cultural differences related to power distance and field dependence, which have been reported in the literature. Teaching styles seem to simultaneously result from the cultural context as well as reinforce it. Science and engineering instruction in the Japanese educational context tends to reflect and reinforce a personalised transmission of knowledge style, while instruction in the American context tends to match and reinforce learning styles characterised by impersonal, inductive thinking.
