My wife and I did the last 10%: sanding the plaster, painting the walls, installing the new cabinets, plumbing the sink. The job was finally done August 20th. It is reassuring to know that the bathtub is MUCH less likely to fall through the floor, and it certainly does look cleaner and brighter now!
What does all this have to do with flipped classrooms? Uh, not much really. Except I think there is a metaphor somewhere about projects that got a lot more work than the naked eye can see. When I look at these walls, now I know what's behind them and how much effort it took to make the bathroom look this way. Same for the dishwasher, which required at least 8 hardware store trips in 2 days.
Our students only see the videos -- not the script / planning / outtakes / editing and everything else we did for several hours to produce that 10-minute lesson. Does that matter? Probably not. We get better at these jobs over time, and with experience it gets easier. This year's dishwasher job was easier than 2016 when I'd never done that before; installing the upstairs sink was just like when I did it for the kids' downstairs bathroom last year.
Nothing else in this house is allowed to break until June. I just won't have time for that until Summer 2019.
