In this paper we discuss how two different types of professional development projects for school teachers are based on the same framework and are used to prepare knowledgeable and effective teachers of statistics. The first example involves a graduate course for masters' students in elementary mathematics education at the University of Haifa, Israel. The second example is a graduate course for in-service secondary mathematics teachers, at the University of Minnesota, United States of America. The framework used is based on six instructional design principles described by Cobb and McClain (2004). Our view of such a classroom is a learning environment for developing a deep and meaningful understanding of statistics and helping students develop their ability to think and reason statistically "Statistical Reasoning Learning Environment" (SRLE).
