Intelligence, perhaps, is not a thing, it's a process; one that never stops. Those who are willing to submit to the fact that they don't really know much at all are the most intelligent because they have everything to learn... therein lies the process. At the core of intelligence as a process is the concept of thinking.
A culture of learning is a culture of inquiry; one that supports discovery and values creativity. We need to create this culture in our classroom, and Bloom's Taxonomy is the place to start if we want to combat the fear students feel toward getting stuff 'wrong.' To promote discovery and creativity we need students to advance their thinking so learning (intelligence) becomes a process for them; not a means to an end (the end being knowledge.)
