Here is a big benefit of flipping: parents can see exactly how and what I teach their children. The goal of almost every homework assignment is crystal clear. Students need to know and understand the main points of the 10-minute-or-so video presentation. Didn't get it? The first step should be to watch it again. Do you really want to be an involved parent? Then you can watch it too and help quiz him/her on the information! The scene on the right will hopefully never occur. (Or at least it won't be my fault!)
As a parent of a 4th and 6th grader, I would LOVE to know more about how my children learned math techniques like factoring, or scientific processes. Otherwise I have to rely on my own memory of those topics when homework troubles arise.
Flipping takes effort to execute, but it really helps keep parents off my back!
Between last year and this year, I have received exactly four parent complaints about the flipping technique (out of almost 200 students). In three of those cases, many other home and family issues were involved. It wasn't really about the flipping; my unusual method was an easy target and scapegoat to divert from other factors. In the other case, there was a fairly legitimate computer access concern which we resolved with in-school special education services and some deadline extensions.
