Lots of this stuff gets built with very little thought on how it's supposed to integrate into a classroom setting. None of it even attempts to integrate with the student grading or scheduling system(s).
We expect public school teachers to be:
* Very well educated. * Emotionally mature and able to understand/handle emotionally immature students. * Very good at their jobs. * Able to understand the dizzying array of laws and regulations around education. * Handle the politics of education(around what can be taught or not, what books can be used, etc.) * Having students who were promoted from the previous grade, even if they can't do previous grade level things(like say HS students that still can't read). * Teach to a test. * Teach to an individual up to their ability. * Teach 30+ students at once at the lower grades. * In Middle School/High School teaching over 200 unique students in a day. * Dealing with unreasonable demands by some parents. * Some students having special needs, diets. * Having little to no classroom level funding. * Understand and be educated in the latest tech. * In some states teach students that are hungry. * In some states carry guns to protect from school shooters.
All while also being paid poorly, if not terribly.
Sure, I can totally see that working out well.
If we paid teachers like we paid any other professional job(lawyers, doctors, etc), I guarantee we will get much higher calibre teachers. Teacher pay in the US hasn't even kept up with inflation over the past decade. Not to mention salaries of all the support staff around teachers to help them thrive in the classroom.
