TPACK and Science/Math Technologies

During class this week, I learned about the three different types of knowledge all teachers should have: content knowledge, technological knowledge, and pedagogical knowledge. When all three knowledge types are combined, it is called TPACK--technological, pedagogical, content knowledge. TPACK is the type of knowledge all teachers should strive for.
Content knowledge is knowing about a subject, such as science, math or history. Technological knowledge is knowing about computers, the internet, and software. Technological knowledge deals with knowledge about anything technological. Pedagogical knowledge refers to the methods and techniques used to teach others, especially children. Pedagogical knowledge is knowing how to teach. Each of these three knowledge types can be combined with one other knowledge type:
PCK is Pedagogical Content Knowledge which means you understand how to teach subjects. Technological Content Knowledge, TCK, is knowing technology involved content. This type of knowledge refers to the use of technology to teach content (as a teacher, this would be in the classroom). An example of TCK is a scientist using scientific equipment.
TPK, Technological Pedagogical Knowledge is knowing how to teach using technology.
TPACK is the right amount of pedagogical, content, and technological knowledge used in the right way. TPACK is what every teacher should aim for.
Also during class this week, we explored different science and math technologies. I really enjoyed exploring Stellarium, a program where you can see different views of the sky at any specific time and place you want. Stellarium is a great way to learn about and see different aspects of astronomy. This was a fun program that is very educational. I also enjoyed playing with the digital temperature probe and the digital microscope. These are great educational technology tools that are useful in a classroom setting.
