Classroom clickers!!
This is a tool for teachers, to help assess students’ understanding of concepts and their engagement with the material. With some tools, teachers can project questions onto their screen using while students answer them in real-time. Students’ answers show up on the teacher’s phone screen, and teachers can see which students got answers right and which didn’t. This gives teachers an accurate picture of how students are following the information, and adjust their lessons accordingly.
Note, this is more of a general recommendation than an endorsement of a specific clicker tool or app. The problem with this otherwise ‘no-doubter’ recommendation is that many of the clicker tools are expensive–at least the ones we know of. Plickers, iClicker, Top Hat, and other tools are not only not free but often have monthly subscription-level pricing. If your school has the budget and you put it to good use, it’s likely worth the investment.
