My father-in-law is one of the most highly-educated people I know (several PhD's in education, etc. plus any number of bachelors, masters, etc. in all kinds of subjects), and teaches all over the world and is HIGHLY sought-after. Chinese schools were offering him huge sums, Kuwait, the US, Spain, UK, all over.
He has a bunch of published papers on education, and has been teaching for over 40 years.
He has always, and still is, against homework in all forms.
Same guy, for reference, who took a job at a school in Spain purely to get my daughter a place in one of the top private schools there. The condition of him working there was that she got a free place. They agreed.
He took the worst classes and transformed them within a year. To the point that the school accused him of cheating on the exams. So, because his students loved him so much, he had another teacher set another exam, and the same students VOLUNTEERED to come back under exam conditions, sit a similar exam, in invigilated conditions, without any influence, connection or presence of him... and they all passed on their own merits... every one. Not just passed. A's all around.
Then he left, because he was insulted by the accusation. But he just needed to prove his point.
Any number of doctors, lawyers, etc. owe their education to him, all over the planet.
And he hates homework and never sets it or, if he's forced to, it's always pathetic and he doesn't bother marking it. He thinks it's an absolute waste of time.
As someone who has, similarly, spent their entire career in education... I can't say I disagree with him on that.
