I wonder what effect the pandemic had on this move to online instruction?

I wonder if one of the reasons is student attention. I know when I am sitting watching a video, it doesn't hold my attention as closely as a live person talking to me. Is there also an interaction piece to this? Sitting and watching a talking head on TV and not being able to ask that person to re-phrase their comment can make learning more difficult for some.

I find it very interesting that schools reduced the use of audiovisual instruction while the military and industry increased its use. The military and industry relies on standard procedures and can cover a larger geographic area. They need all of their members/employees to do the same processes the same way regardless of if they are in NY or CA. How long have lesson plans been used in education? I'm not familiar with grade schools curriculum. Is the same information taught in 4th grade in NY and in CA?

I'm probably opening a can of worms with this, but did they really need to add and, looking forward, retain the term ethical? Shouldn't teachers/educators act ethically?

I like this definition. It's clean and concise, but does it hit all domains of learning (Affective, Cognitive, Psychomotor)?

These are great! I use these all the time in my class. I have students give a short (no more than 1 minute) talk on their understanding of a pathology.
