As a classroom teacher, this diagram makes sense to me. I can use this concept/framework as I plan my lessons, as it shows how technology can enhance the classroom in any subject without teaching technology lessons per say. I should be able to teach my content and infuse the technology. If I learned anything from this session it is that content is most important piece.
So how do I implement TPACK into my classroom you might ask? Start simple. Using this diagram as a framework for your lessons, start by breaking it down; ask yourself what content do I want my students to understand?
TPACK is an outstanding pedagogical framework for working with technology in education. If you want to learn more, just google it. Oh, and you can click through below for two practical examples.
