Realistically, a “with it” teacher can teach almost anything using almost anything. I’ve been taught trigonometry using a paper clip, and expository structure using paint. Tech is great, but nowhere close to necessary. But if the underlying learning process is well-thought out, tech can provide powerful common ground for teachers and learners.
So then, video games.
Video games do not represent a “rising medium,” but rather one that’s established, potent, and ready for application in any content area at any grade level. While their application may not be as immediately apparent as the Declaration of Independence, an essay by Wendell Berry, or Google Earth, they truly are a goldmine of edu-content.
