Curriculum must drive technology, not vice versa. Mitch - if learning is about delivering information, then that approach fine. But learning is more than that. All types of problems. Ability to listen to the thinking of young children.
Teachers are generally talkers, rather than listeners.
In too many cases it is not the children. Gentleman bringing in snake, show it put it into sack and take it home at end of day. Or pet rabbit hopping about class then back into cage at evening. Biology or science is just a small part of the day, and special or isolated part. Not central - a very limited experience.
