The study investigated the effects of using the problem of the week in teaching (POWT) on teachers' learning and changes in knowledge and teaching skills, in algebraic thinking and algebra tasks, in the setting of a university mathematics education graduate program. The graduate students participated in learning POWT weekly in a mathematics…

This article explores one segment of an extended research and development project that was conducted to better understand the ways online teacher professional development can support teachers' development of deep and connected mathematical understandings. In particular, this article discusses teachers' understandings of the concept of…

The increased popularity of lesson study in the United States--an approach to professional development initiated in Japan more than a century ago--is due in large part to findings from the 1995 Trends in International Mathematics and Science Study (TIMSS) video study and the subsequent book, "The Teaching Gap" (Stigler and Hiebert 1999). "Lesson…

This study explores the mathematical problem-solving process of trainee teachers in a teachers' training institute. This research adopts a constructivist perspective that views learning mathematics as a process of constructing meaningful representation and knowledge as being constructed by the individual. The research methodology employs the case…

This article describes how teachers learn to implement problem solving in their classrooms through participation in an evolving problem-solving class. (Contains 3 figures.)

Details of a course on mathematical modeling for graduate teachers of mathematics are presented. The rationale, objectives, course content, assessment methods are discussed along with several illustrative examples and difficulties encountered in finding appropriate problems. (MP)
