TPACK : the way I understand it.

They are big words put together, 'Technological Pedagogical Content Knowledge'.  Too much jargon for a simple layman understanding.  It is simply the effective way to teach with technology.  

According to the above diagram, it is quite explanatory that TPACK is the point of knowledge which combines technology, pedagogy and content.  To teach effectively, as teaching with technology is a wicked problem, teachers have to come up with creative solutions and design a total package which is :

               Novel
               Effective and
              Whole,

in order to solve that "wicked problem".  (For a deeper understanding and more in depth explanation, we can refer to the SITE keynote presentation by Matt Koehler and Punya Mishra.)   

Technology is always changing, and when presented with a 'NEW' way of learning and teaching that would be able to hold the students interest, for example using the iPhone technology, or introducing learning through a computer game, the CONTENT would then be of more interest to the student, simply due to the way it is presented (pedagogy).  Teachers simply have to keep up with the times.  As the saying goes, you can't teach an old dog new tricks, teachers can't use their old wayward and boring tricks to teach the children of the digital age.
