Talking on STEM and classroom modules. I am not an expert?? I have been teaching in the university for 30 years, observing failures from schools trained or advised by the experts (?). New students in the universities do not have strong basic in science. What the did in school? passing exams, collecting As or understanding science? After retired I will do my way to help them. I think I am strong enough tgo change because we have more than thousands graduated from the Department of Biology UPM. If I can get 100 good one we can change.
