teachers sit around students and watch them all the time?
creepy.... I had a colleague who forced students to do written exams with the cameras on their hands... I can't do that - I feel like a member of the Stasi....
Poland is too focused on products (exam results) and not on process (study habits, understanding processes rather than memorizing facts).
I remember the difference between statistics in the US and Poland. In Poland, as described to me by students, they mainly memorized formulas and equations and had no chance to actually use them.
In the US during tests they provided us with a sheet with all the formulas... most of the test was about knowing what formula to apply to what problem.. and finding the right answer too but that was only possible if we knew from the problem which of the half dozen or so formulas was appropriate. I had dreaded statistics but ended up enjoying it a lot.
The US system has problems too and is not to imitated by other countries but my natural inclination is to not put too much stock in high stakes test results....
