To help you visualize how these 3 knowledge areas are combined, look below at the graph I made.
It's right at the center, where you can see how Content (Subject or the What you are teaching), Pedagogy (How you will teach), and Technology (resources) meet to create a dynamic learning environment for students. You can check out my video on TPACK and the examples I used to show how TPACK can be used in the classroom.
So to the right is a chart I made to define what each knowledge area consists of. It's important to note the role of each area in the framework of TPACK. Don't feel overwhelmed thinking about this concept. It's simple! It is as easy as creating a lesson plan for your class this week. Remember that we are the teachers of 21st century students who are growing up using technology for everything! So if we can do the same in our classrooms and engage our students in the educational path of technology, I believe we will have a great impact on their learning.
This website is an excellent example of integrating technology in your lesson. I XL is an online program that allows students to sign in with a username and password and work on different areas/ subjects. The great thing about it is as that teachers have access to the students progress and can monitor how far they are and howl much they are learning.
After researching what TPACK is, I really understand how important technology should be in our lessons. So don't stress out about having to learn to use technology but embrace it as an effective teaching tool to turn on the light bulb in your students brain.
