Teaching is the only occupation I know where people who have never taught think they know what constitutes “effective” teaching. It is also the only occupation I know where these same know-nothings want to tie pay, job security, etc. on WHAT OTHERS DO, NOT on what the teachers do. Teachers have NO control over students’ learning–it is strictly up to the desire or the ability of those students to learn.
VAM is just another scam, another sham.
