This may sound naive but I was amazed to read that 1 hour of online instruction could take as many of 10 on the instructors side. Likewise, students need to allocate more time to be successful online than I had anticipated. I assume those are expectations for adult or university students. I can easily see that much time on my part in building (let alone supporting) my courses. I can predict though that for my high school classes (9th grade), they could easily become overwhelmed and I will need to chunk for everyone as if they were one of our special populations (ELL, SPED, remedial).
