  • Classroom confusion measured in real-time

    - A new app lets teachers track whether students understand lecture presentations or not. Instead of using end-of-the-year evaluations, real-time data is produced. This would be especially useful in large lecture halls, its inventor argues.

    Technology plays an ever bigger role inside and outside classrooms. Algorithms have been particularly successful as anti-plagiarism and anti-anti plagiarism tools. Meanwhile, multinational innovators like Apple and Google redefine education by transforming text books into learning modules or by creating social media enhanced study environments.

    One of the more recent teaching innovations is the app "Understoodit" which allows lecturers to track classroom confusion in real-time. Instead of giving feedback when all classes have finished, students can vote via smartphones, tablets and laptops during the lecture whether they understood the material or not.

    Real data from large classrooms

    Liam Kaufman who created the app argues that this is especially useful when classes are taught in big lecture halls. "It's anonymous, so it lets students communicate whether they're getting the lecture or not, because once a class has 60 or 70 students, hardly anyone raises their hand. It's also helpful for students who don't speak English as a first language, and it works through the browser on your iPhone, laptop or tablet so there's no cost."

    Teachers have already picked up on the service with first experiments starting at Harvard, Stanford and co. A teacher at Duke University describes his experience: "I stand for more than an hour in front of a class delivering information, but usually the first sign there's a problem is when a trail of students follows me after class with questions. How much better would it be for me to know right at the time? I try to study faces looking for quizzical looks. So to get real data would be great. I'm a psychologist, not a psychic."
