More than one in every four public schools and two-thirds of all universities in the U.S. offer some sort of distance learning for teachers (Market Data Retrieval, 2004, p. 69). The most frequently cited type of online professional development is the online course, which is provided by schools, districts, regional centers, national organizations, universities, and independent consultants. Classroom Connect’s Connected University offerings for teachers are examples of this popular type of professional learning experience.
