What does this word really mean? TPACK

As I was going through study desk, I came across the word TPACK.
What does this word really mean ? I thought to myself. The only help resource that goes through my mind when, I do not know something; MR.GOOGLE. I goggled and came to understand that it actually stands for content of knowledge, pedagogical knowledge and technological knowledge.  Below, you can see and understand more about each of the part which stands for

TPACK;

• Content Knowledge (CK) – Content Knowledge is knowledge about the actual subject matter that is to be learned or taught. As Shulman (1986) stated, teachers must know and understand the subjects they teach, including: knowledge of central facts, concepts, theories and procedures within a given field; knowledge of explanatory frameworks that organize and connect ideas; and knowledge of the rules of evidence and proof (Koehler, 2011a).
• Pedagogical Knowledge (PK) - Pedagogical Knowledge is deep knowledge about the processes and practices or methods of teaching and learning and how it encompasses (among other things) overall educational purposes, values and aims. Pedagogical knowledge requires an understanding of cognitive, social and developmental theories of learning and how they apply to students in their classroom (Koehler, 2011b).
• Technological Knowledge (TK) - Technology knowledge is knowledge about standard technologies such as books and chalk and blackboard, as well as more advanced technologies such as the Internet and digital video. This would involve the skills required to operate particular technologies(Koehler, 2011c).

This three important component must work together in order to let the teacher to achieve in their teaching. Teacher need to have sufficient information and resources regarding the 3 component to make the lesson more effective. Teacher must always know to make creative links between what is being learned (content), how it is taught (pedagogy), and the appropriate tools (technology). I find the TPACK  something interesting and different as; I never heard about it before.I  would love to try to use the component of TPACK  in my teaching and see the effect on my kids at school.
