Google has announced several new features for its Google Classroom product today, including new ways for parents and teachers to shut off access to apps and browsers when students should be sleeping or focusing on coursework.

Now, through assigning quizzes in Google forms, teachers can lock students into the assignment and keep them from browsing the internet or searching for answers elsewhere. Another new feature will allow parents a little more control of the school-issued devices by being able to set “off hours.” The controls are similar to most parental control functionalities on devices like the Fire tablet or Kindle, which limit children from accessing certain apps and content.

New hardware is headed to educators as well. Google announced the launch of the Acer Chromebook Tab 10 and the Staedtler Noris stylus. The Tab 10 is the first tablet to run Chrome OS. The Staedtler Noris stylus is built to resemble the look and feel of a traditional pencil, and it will be compatible with a suite of apps by the time the next school year starts.
