I’m not a maths teacher, but when I saw this I immediately thought of how it could be applied to teaching. Been looking at Download Squad (a fave site of mine) and noticed a post about Trendrr – a graphing tool that lets you compare and graph social data from popular websites such as YouTube, ebay and myspace. According to Jay Hathaway;
“Trendrr makes graphing simple by including a drag-and-drop scratchpad that lets you edit and compare graphs with a minumum of effort. “
It may well be that many of these social network sites are blocked in schools which may limit its effectiveness as a Web 2.0 tool in classrooms. I couldn’t help but think, however, that this would be a great site to be using to get your students interested in comparing data from sites that they use in their everyday lives – a bit of real life maths! Perhaps teachers could create some graphs before class and have them ready so students can draw conclusions from the data. We all know how much more attention we pay to things when they have relevance in our lives. Thinking about it, could be a great tool for Humanities teachers looking at the human condition and social trends.

Thanks for sharing this. I am sure that I could use it as a discussion point in Info tech as well. Will check out the site.
