Teacher Explanation of Physics Concepts: a Video Study

Abstract

Video recordings of Year 11 physics lessons were analyzed to identify key features of teacher explanations. Important features of the explanations used included teachers' ability to move between qualitative and quantitative modes of discussion, attention to what students require to succeed in high stakes examinations, thoughtful use of analogies, storytelling and references to the history of science, the use of educational technology and the use of humor. Considerable scope remains for further research into teacher explanations in physics.
