One of the online tools mentioned in the later modules of TRIG was the student response system Socrative. Socrative is an easy to use app that allows teachers to assess their students progress with exercises, games, and polls. Students and teachers can run the app on their tablets,smart phones, or laptops. Teachers can create their own content or use pre-existing content with their students. One of the best features of Socrative is that student responses are displayed visually on the teacher screen in real time. Teachers can also export them to Google spreadsheets for future use.
Socrative is a great pre-assessment tool for use at the beginning of a unit. It can also serve as a nice out the door style of assessment. I hope you take the time to explore using Socrative in your classroom. Let me know if you have any questions!
