A good example of some CK related to history, but also an example of an online service that aims to generate good content by using the "wisdom of crowds". A little like wikipedia. Quora allows people to ask questions that are answered by large numbers of people, the best answers rising to the top.
A Vine that illustrates the evolution of technology on a office desk from 1980 to 2015. Two questions.
What would a similar Vine of a classroom look like?
This Vine shows an evolution over the last 25 years, what would a 2040 Vine look like? What would it would look like for your classroom.
This article frames PCK specifically to the history subject and helped to frame my understandings for this aptitude - when I initially read it the whole chapter appeared.
I chose this item as it is a handy item for a history teacher to utilise. A lot of these contemporary issues come up in the classroom and utilising this to correct errors in textbooks and information delivered that is not quite accurate, can aid in a students education and a teachers development equally.
Somewhat interactive timeline that shows the various generations mapped against technical developments (e.g. when the term "blog" was coined, when the Mosaic browser was developed).
A description of the 1st one-to-one laptop program in the world (at a Melbourne-based private school). The important aspect of this is the purpose behind this program and how that differs from what has happened since. Arguably, how computers and computing devices are being used in schools has radically decreased even though the capability of the technology has radically increased.
I found this article really interesting after an experience in two year seven classes a few weeks ago. I was asked to help two grade 7 classes for the first 2 periods for three weeks. In that time, I wandered around quietly paying particular attention to what the students were actually doing on their laptops. I noticed on many occasions, several of the children were actually entertaining themselves by just "pottering" around on their laptop, even while the teacher was explicitly teaching. I was really curious to know how much the majority of students were actually learning. The class environment was relatively quiet compared to schooling in my day (in the '70's and '80's) but I had the thought, if laptop programs are NOT successful, we have a big problem that may not be confirmed for a decade or so. The other thing I found interesting is that the majority of the year 7's had done extremely poorly on their ICT exams.... interesting...
