SNAPP is a software tool that allows users to visualize the network of interactions resulting from discussion forum posts and replies. The network visualisations of forum interactions provide an opportunity for teachers to rapidly identify patterns of user behaviour – at any stage of course progression. SNAPP has been developed to extract all user interactions from various commercial and open source learning management systems (LMS) such as BlackBoard (including the former WebCT), and Moodle. SNAPP is compatible for both Mac and PC users and operates in Internet Explorer, Firefox and Safari.

Monica Rankin posted a video to YouTube about how she uses Twitter in her classroom at the University of Texas. Somehow this Monday morning the video showed up on the page of the most popular bookmarks for the day on Delicious. It had only been viewed 425 times and neither Rankin nor we could figure out how it got bookmarked so much in that one random day. It's a very good video though, so we wrote a blog post about it that saw an unusually high 12,000 views within 24 hours. We decided to pay very close attention to where those readers came from, just to see what we could learn, and some unexpected trends emerged from the data.

In 2005, Jorge E Hirsch of UCSD published this paper in PNAS in which he put forward the h-index as a metric for measuring and comparing overall scientfic productivity of individual scientists. The h-index has been quickly adopted as the metric of choice for many committees and bodies.
The h-index (Hirsch Number) is a metric that is increasingly becoming of interest to researchers, especially in the light of the REF. An h-index is “a number that quantifies both the actual scientific productivity and the apparent scientific impact of a scientist“. You can work it out manually, but to be honest you’d need to be mad or a bibliometrics fiend to want to.
