Education is an odd profession. Where people feel because they have had an education they are qualified to determine best practice. It is as if having an operation makes one feel as they understand the best practice in heart surgery. Teachers spend years studying teaching practice, always read the research on best practices, spend all day working in education settings. Yet people often dismiss their methods and demand change based on often misremembered anecdotes of their own youth over half a century beforehand and pride in their children. I wouldn't be shocked if a vast majority of parents thought their kids were above average, which isn't a bad thing, but sometimes professionals know what they are doing.
