We have been using an app in our Digital Literacy class called Socrative. It’s a simple to use student response system that works with any web enabled device. So, you don’t need an app in order to take advantage of Socrative. You can simply have your students go to Socrative.com on any computer, smartphone or tablet and you are in business. Socrative will also email you a spreadsheet of the responses when you are done with a specific activity. Best of all, it’s completely free to use.
Here is a short overview video that will show you how Socrative works.
As always, please let me know if you have any questions or suggestions.
