Studies of teacher quality have shown that teachers who know more mathematics generally have students who achieve at higher levels in mathematics (Darling-Hammond, 2000; Rivkin, Hanushek & Kain, 2005). Researchers agree that teachers who know more mathematics will communicate more of it, and communicate it more precisely and correctly, than teachers who know less of the subject. But designing professional development aimed at increasing teachers' knowledge of mathematics can be done in many ways with varying effects on classroom practice (Loucks-Horsley, et al, 2003; Boyle, Lamprianou, & Boyle, 2005; Simon, et al, 1991).
Teachers' knowledge of mathematics is typically measured in terms of an undergraduate degree or certification in mathematics. But researchers agree that there are different ways of learning mathematics and that teachers' beliefs about the nature of mathematics and about themselves as learners of mathematics has a strong influence on their classroom practice. This "what you teach is what you get" (Cuoco, Goldenberg, & Mark, 1997; Wu, 1999) principle has been shown to account for much of the variability in student mathematics learning.
This session will examine and challenge the nature of evidence for claims of effectiveness for the mathematics-intensive professional development activities offered by four MSPs. All four of our MSPs offer professional development in the form of significant experiences of mathematical / scientific investigation for teachers. These take various forms: "teacher institutes" or "immersion experiences" or "study groups" and in most cases they engage teachers over a span of several years.
The goal of this session is to facilitate a broad discussion around the following set of questions:
The session will be organized as a panel discussion, interspersed with a sequence of short presentations by panelists from the four MSPs.
