Hi Jason! Thanks for your feedback. I wish I had some data about whether students would use it here—my workplace actually doesn’t allow students to use their phones (though most private schools do). In place of this (and I really should have mentioned it) I asked some of my coworkers about this phenomenon and if they would try a service like this int he classroom. Most of them voiced that they have “too much content to cover” to allow chatting and collaborating in class (which points to differences in teaching method), and also expressed concern that even if they do ask students if they understand during the lesson (or ask comprehension questions), most students will sit and stare blankly, or reiterate what they just heard to prove they were paying attention instead. It’s a bit of a band-aid solution to a knot of problems—old, lecture-style teaching, examinations that test recall instead of comprehension, the social norm to not stick out, the idea that making mistakes is shameful, scolding students who make mistakes, and the idea that ‘if it’s challenging it must be good’. I don’t believe this knot is something we can fix quickly, but at the very least, it can lower some of the affective barriers to class discussion. There is also the potential that teachers can ask students a question and ask everyone to respond via the app. It lets more than one student participate, easy to see their ideas clearly, and should the teacher be keeping track of participation, they have a paper trail. In no way would I hold this up as an answer to lesson disengagement, but it may be a step along the way to active learning. Thank you for the feedback about the cell phones being disruptive. Given this, perhaps making the app ‘float’ on the screen, thus blocking anything else that may distract students, might be one way to solve this. Thanks again!
