TPACK

My understanding of TPACK is that it is the ability a teacher has in delivering content as well as pedological information. It can be divided up into "content knowledge," "pedological knowledge," and "technology knowledge." These can be combined into subgroups such as content and technology knowledge, but when they are all combined, it's called TPACK. If a teacher can teach using TPACK, he/she will deliver information in a most effective way.
