In this study, the author examined the relationship between teaching approaches and thinking styles in teaching. The study parallels previous investigations (Zhang, 2000a, 2000b; Zhang & Sternberg, 2000) of students' learning approaches and thinking styles in learning. Seventy-six in-service teachers from Hong Kong responded to the Approaches to Teaching Inventory (K. Trigwell & M. Prosser, 1996) and the Thinking Styles Inventory in Teaching (E. L. Grigorenko & R. J. Sternberg, 1993) as well as to a range of questions designed to assess the participants' perceptions about their work environment. It was concluded that approach and style are two overlapping constructs with different labels. The differences between approach and style are in degree, but not in kind.
