Stats stud Mark Schneider of the American Institutes for Research graced our studio for the latest Education Gadfly Show podcast episode, now available here. You won't want to miss Mark's pontifications on the latest TIMSS results and his take on "advanced topics" courses. Also: Amber dishes on a charter school study and Stafford reports on yet another way schools are cutting costs (hint: caffeine addicts won't be amused). Listen to all this and more on the Education Gadfly Show!
