This came in my inbox today, so I figured it was safe to share this previously "secret" feature.
If you're new to Socrative, the web and app-based service is a formative assessment and survey tool that can be accessed via PC, Mac, or any web-enabled device. (Which comes in handy when the app gets glitchy some days and I can switch to the web). I wrote more about using Socrative to replace Scantrons if you want more info on practical application and a comparison to using Google Forms.
Adding images and auto-grading short answer makes Socrative a powerful tool.
My Algebra 2 students have a short assessment on exponential functions tomorrow, so this seemed like an excellent opportunity to run Socrative through the paces and embed some beautiful exponential functions from everyone's favorite web-based graphing calculator, Desmos.
Here's a screencast of my workflow this afternoon:
I'd REALLY like to be able to add images to my MC responses, also, but overall, I'm very excited about these additions to Socrative. I don't know how they keep it free and rival many paid services, but I'm thankful!
