John Taylor Collegiate is using technology to help students get the most out of every lesson.

The device is called “The Juno.” Math teacher Keith Goetz wears it around his neck during class and it records everything he says. It also syncs with his lesson on the classroom smartboard. After each class, Goetz uploads the lesson online and students can review what they just learned as many times they like. It’s a virtual classroom.

Goetz was the first teacher to use the device at the school but the results have been so positive, the entire math department and some French and chemistry classes have also followed suit. Each device costs about $1,200.

Goetz says the technology let’s students learn at their own pace and keeps them on track if they ever miss a day of school.
