Why do so many promising ideas generated by education research fail to penetrate the world of classroom practice? In "From the Ivory Tower to the Schoolhouse," education historian Jack Schneider seeks to answer this familiar and vexing question by turning it on its head. He looks at four well-known ideas that emerged from the world of scholarship--Bloom's Taxonomy, multiple intelligences, the project method, and direct instruction--and asks what we can learn from their success in influencing teachers.
