Students responses are always enlightening - I quizzed some students recently about what teachers could improve on. The responses 'stop teaching us stuff we already know' certainly caused some deep reflection. What percentage of kids feel challenged on a daily basis? How many learn in-spite of what we do?
One needs to direct some more conversations with students and teachers about getting to that ZPD (Zone of Proximal Development) Vygotsky. After all isn't that the best way to develop Life Long Learning attitudes and dispositions?
