In my opinion, Technological Knowledge is easy to understand. After reading this article, it is my understanding that within this context, technological knowledge is knowing how the technology within a classroom works. For example, knowing how to turn on a projector and properly display items through that piece of technology. It could also be something as simple as being knowledgeable about using a chalkboard! (of course the technology we have in our classrooms today are much more advanced then those two examples, but those examples were just to get an idea of what technological knowledge is.) <– For todays day in age, I would say that knowing how to use finale, or garage band would be another example of Technological Knowledge.
When it comes to Pedagogical Knowledge and Content Knowledge, the two kind of go hand in hand. Pedagogical knowledge is basically just knowing how to teach, which comes through experience of course. Content Knowledge is exactly what it says, the content. Its knowing what you are teaching! Plain and simple. For example, i think that an example of Pedagogical knowledge would be as such: If a teacher is trying to teach something as simple as how to sing a major triad, she must first know HOW to teach that to her children. AND she must know how to sing a major triad, herself. <— thats an example of content knowledge! (i hope i am actually correct!, but thats just what i pulled from the article and my own research!)
Vignette: A well-developed choir teacher at Basha High School, entered their 5th period all women’s choir class. The women were all nicely seated on the risers awaiting his instruction. They were in the middle of learning a beautiful song at that time in the semester. Each day they would start class by listening to an advanced college choir sing the same song they were preparing to perform. This teaching technique of listening to song that needed to be learned, was really help to the girls. The teacher walked over the sound system, where he put in the CD and adjusted the levels in order to listen to the track. As the girls listened to the music, their teacher asked them to imagine how to make the first phrase of the song more legato and as one, instead of separated or staccato. He showed the girls a sweep-like motion to indicate what he meant and show them how he wanted it to sound. Because he knew how to use the technology, knew what he was teaching, and how to teach it, his class was able to better learn the concept and overall perform better as a choir!
