Facts strongly disagree with you. Research has shown time and time again that almost everything beats the old teacher lecturing the class full of pupils at their desks. The problem is that none of these are ever implemented because 1. Lobbies of unionized unfireable teachers refuse to be told how to do their jobs. 2. School boards on ever shortening budgets rely on cramming even more students in the same old class as de-facto cost control tactic. 3. There's actually very good money to be made in substandard educational supplies. p.s. And you are wrong about exercise too. While it is truth that it is not possible to get any results without breaking a sweat, exercises themselves have changed over time. It is now possible to achieve your goals in less time with less risk to injure yourself by hiring an instructor than trying to blindly emulate what you were taught a couple decades ago in high school.
