Noted education reformer John Dewey believed in active learning that should not be limited by process. We cannot give ideas directly to students as if they were "bricks" and expect them to engage with them in a way that is lasting and educationally meaningful. In an interesting article in "The Art of Teaching Science," Jack Hassard, Professor Emeritus of Science Education at Georgia State University, explores Dewey's thoughts on learning as an interactive "informal" process in light of today's science standards. One of the conclusions he reaches is, "To create science standards that reflect a consensus among researchers in cognitive science, they must be written in such a way the content aims are combined with the skill or processes needed to help students have a chance at meaningful learning." Good stuff.
