TPACK stand for Technological Pedagogical Content Knowledge. From what I understand these are three areas of knowledge that teachers should be striving to acquire. You can also have new kinds of knowledge that lie at the intersections between the three subjects. Considering P and C together we get Pedagogical Content Knowledge or (PCK). I think it is important to learn each of these things and try to incorporate them into our classroom. Technological knowledge is probably the hardest section for me but I understand that with the way our world is going, it is very important to keep up with technological knowledge to help me and my students learning.
