A few weeks ago, I was called a "monster" for suggesting that teachers may lose their jobs if they don't go back to the classroom. I was not advocating that they lose their jobs just suggesting that innovation, technology and need would combine to reduce the importance of face-to-face teacher/student contact which could result in the loss of teacher jobs.
Remote learning with the student staying at home is not a viable solution because parents can't leave their children at home alone while they go out and earn a living. And what do you know: along comes Prenda to fill the gap.
I do not advocate Prenda but, with some enhancements (i.e. require more training, accountability, background checks, certifications, etc. on the part of guides), the "concept" of Prenda could be a platform to build on. In fact, un-employed teachers with children of their own could become guides for children similar in age to their own. While the teacher is instructing their own child(ren), they could be instructing other children.
A major question to be answered is where to get the content that would be used to "guide" the students. Answer: the school system could have teachers make a video their classes and make those videos available to the "guides".
Teachers won't like the concept of Prenda; there is no security, no union, no pension, etc. They would become just another cog in the gig economy. But, if we can't get back to face-to-face teacher/student interaction, something akin to Prenda could be in our future.
Recent guidance from the CDC indicates that 6 feet is not enough distance between people in an indoor situation to prevent the spread of the virus. The only way out of this pandemic is an accurate, rapid (i.e. a few minutes or less), cheap and easy to administer test. People, in large numbers, will not take any vaccine authorized by Trump administration officials until it becomes obvious that it is safe and effective. So, alternatives to large gatherings that will allow people with school age children to get back to work may be with us for a while.
