Instructional Development Timeline

The Great Depression and the Progressive Movement (ironically) slowed progress in the development of instruction. Bad economics caused less funding to pour into research and development in education. Social reconstructionists (a group of educators) responded to the economic situation by advocating curriculum courses that focused on economics and politics. The Progressivists hindered advancement in instructional development because of the shift of focus on student-initiated activiites rather than pre-specified outcomes.
