As teachers, we have used many ways to gauge student understanding and attempt to hold the interest of students throughout an entire day. In the early days of our teaching, we used everything from little popsicle sticks with red on one end and green on another. Not much later, we were introduced to clickers, by eInstruction. We got a couple of sets of those, and they were the best thing since sliced bread. After several evolutionary cycles of clickers, we have now progressed to a 1:1 classroom.
We are blessed to have a great group of administrators who support us, and keep us well stocked on tech to make our paperless classrooms go. We have class sets of chromebooks, and that has enabled us to make use of a great website….
There are many advantages to using socrative. You get real time feedback from students, and it is more than just multiple choice. You can throw questions out there via computer, ipad, etc. and have kids answer. The sky is the limit. You can get reports sent to you to use later. You can even use it as a toaster! (ok that one may be a stretch)
If you have not tried http://www.socrative.com, and are in a situation where the tech is there, you need to. Even if you are not 1:1, it has value. Students can work in groups and formulate answers to post.
There are tons of great resources out there for you, and many are free. Take a look around, and share!
