Kahoot has added a new way for students to use the free Kahoot iOS and Android apps. The new way to use the apps is to play games in what Kahoot is calling Smart Practice mode.
Kahoot's new Smart Practice mode gives students an opportunity to focus on the questions that they answered incorrectly during a Kahoot game or challenge. Smart Practice works in three phases. The first phase is immediately trying the questions again. The second phase is trying the questions again after 24 hours. And, as you probably guessed by now, the third phase has students try the questions after 48 hours.
Here's a short video overview of Kahoot's Smart Practice mode. It's important to note that Smart Practice is only available on the Kahoot mobile apps and not in the web browser version.
