A reader comments in response to a post complaining about the quality of teachers:

I am one of those people with an elite STEM degree.

I have volunteered at school as a guest speaker, a parent-chaperone, and occasionally given a lesson in an afterschool program.

I am nowhere near as good as the professional teachers, and nowhere near skilled enough to be more than an occasional Other Interesting Adult. It would be a travesty to put me in a classroom.

I’ve been a ‘rocket scientist’ and I find that to be quite a bit easier.

I support our teachers: they do a job I do not have the skills to do.
