The purpose of this study is to examine the interactions in the learning activity of learners that make presentations using the interactive whiteboard, and to construct a model for instructional strategies adopted by teachers to promote thinking and dialogue among learners. Through a field research by videotaping the learning scene, we conducted an analysis of the speeches and behaviours of the learners and teachers. As a result, several categories of teachers' instructional strategies have been formed; Set up a framework for dialogue; Instruct an explanatory method; Demonstrate a model; Respond to the student's explanation; and Ask questions that promote thinking. Among the components that constitute these categories, we identified some phenomena accompanying characteristic conducts and actions in leveraging the use of the interactive whiteboard: Prepare (=capture/enlarge) the display screen; Advise them to write in explanatory notes; Advise them on the usage of the marks and signs; Change colours for them to make a comparison; Instruct them to save the written-in notes; Demonstrate model standing positions; and Demonstrate model motions and gestures.
