The next big thing

Stephen Downes shared this article about the next big thing in network analysis. He writes: Valdis Krebs argues that the next big thing in network analysis will focus on the contents of what we read (and not just the titles as entities) in order to draw connections between people. It’s a natural evolution of network […]

Fixing audio from a video track

The problem: Our students had recorded video of themselves, but the audio from the video was too quiet to hear. Unfortunately, they had recorded their video on a Flip camera from a distance of 7 or 8 metres in a large open space, and forgot (or did not know) that this would result in extremely […]

Mathematics education blogs

Here is a list of people who blog about mathematics or mathematics education. Please let me know if you blog about mathematics education, and you’d like your blog to appear in this list. I’d like this list to be exhaustive, rather than exclude people. You can either contact me, or add your relevant information to […]

Should students learn how to graph functions by hand?

Software to create graphs of all different kinds electronically is ubiquitous. There is no question in my mind that we do students a great disservice if we do not give them opportunities to learn how to use at least a few of these programs. That being said, does the use of these programs potentially make […]

A problem with digital books

(Image credit: Harold Bakker) When I was growing up, my house had a 50 foot wall full of books which our family had inherited from my grandfather with the house. Whenever I was bored, and the weather was ugly, I would pick a book off the shelf and read it. I devoured books from the […]

Separate science history from science inquiry

(Image credit: XKCD) It occurrs to me that we have two goals for science education. One is to teach students what existing science is known, and how it can be applied to our lives, or how it is interesting to us. I call this first purpose, "Science History." The other goal is to teach the […]

Tinkering for students

I watched Caine’s Arcade yesterday (see below) and while it is a bit sad to me that an amazing kids’ endeavour has turned into an opportunity for a film-maker, the movie itself is very touching. I recommend watching it.   Caine is not an unusual child, but he has had a number of unusual circumstances […]

Computing in schools

Gary Stager posted "Dumbing Down" a few days ago, which is a passionate plea for computers to be used for computing in schools. He writes: Although I’m only 48, I have been working in educational computing for thirty years. When I started, we taught children to program. We also taught tens of thousands of teachers […]

The language of technology

Technology has a language, a history, and it shapes our culture. While the focus of this article is on the language of technology apparent in Microsoft Word, every technology we use has similar traits.   Check out the "ribbon" (or menu bar) of Microsoft Word.   First, when you examine Microsoft Word, and many other programs […]
