This student (video: Flipped classrooms aren’t teaching) makes an important point about the damage flipped classrooms do to the teacher-student relationship.

Progressive educators believe in “horizontal” classes as opposed to “vertical,” hierarchical classes. Inside a horizontal class, everyone is a “learner,” and the teacher is just a guide on the side. As a result, the teacher-student relationship is weakened while the peer relationship is strengthened.

It’s ironic because districts like ours spend a small fortune to reduce class size, but our administrators, aided and abetted by parents on the board, use reduced class size to grow the distance between teacher & student instead of shrinking it.

The smaller the class, the easier it is to put all students in groups. Inside larger classes, the noise level alone makes small-group work untenable.

So we pay for small class size, but we get peer editing, learning stations, & flipped classrooms.

Flipped classrooms are especially beloved by progressive educators/constructivists because they move the teacher to video, and you can’t form a relationship with a video. Inside a flipped classroom, eye contact happens primarily between students, not between teacher & students.
