Last week I attended a training session on the use of Socrative. Socrative is a student response system that can be used to create a series of educational exercises including class votes, group competitions and assessments. The best thing about Socrative (apart from it being free to use) is the fact that it provides students a chance to legitimately use their phone in class. The software can be accessed through an app on a smart phone or tablet computer as well as via the internet on a desktop machine.
I have previously used voting pads with my AS students but as I was unfamiliar with the software and found them quite faffy, however as Socrative seems a lot easier to use I will definitely be trying it out with my classes soon.
