"... where homework consists of lectures that were typically given during class time, and in-class time is used for hands-on projects?"
Lectures... hands-on projects... don't people learn by reading anymore?
Let's say there were 2 schools: Reading School and No Reading School. In Reading School, the homework is to read, and in the classroom, there is discussion of the readings, led by a teacher who lectures and facilitates discussion. (This is what traditional law school is like, and what I've been used to for 30+ years.) In No Reading School, homework is to watch a video of your teacher lecturing, and in the classroom, you do some sort of activity.
Which school would you want your child to go to? I suspect the "flipped classroom" is a nice way to refer to a school experience for children who are not expected to handle reading. Am I wrong?
