"Universal design's focus is that barriers to learning are removed and all students have equal access to the curriculum. Reducing the number of students in the margins. Sounds good. Hard to argue.
The flipped classroom affords time to teachers so they can spend more time with students and have more of an opportunity to discover the barriers to learning. When you teach high school science in a full year school (one that is an IB school for example) it is hard to get to know the 200 students you teach. So time is gold.
Flipping gets you that time."
