I went through all those links. I saw some stuff that was close, but not the combination and no one had one class per day, with 6 hours of instruction. The closest was 4 hours and 15 minutes. And they said it was critical for teachers to be trained to teach in block. That trying to implement standard teaching into block teaching didn't work. No one is getting trained for this. And half the class will be at home doing online. Not sure how. I keep asking what technology will be used. No one seems to know.
