Google Classroom is a free web service developed by Google for schools that aims to simplify creating, distributing and grading assignments in a paperless way. The primary purpose of Google Classroom is to streamline the process of sharing files between teachers and students. It was introduced as a feature of G Suite for Education, formerly Google Apps for Education, on May 6, 2014, followed by its public release on August 12, 2014. In June 2015, Google announced a Classroom API and a share button for websites, allowing school administrators and developers to further engage with Google Classroom. In March 2017, Google opened Classroom to allow any personal Google users to join classes without the requirement of having a G Suite for Education account, and in April, it became possible for any personal Google user to create and teach a class.
Google Classroom combines Google Drive for assignment creation and distribution, Google Docs, Sheets and Slides for writing, Gmailfor communication, and Google Calendar for scheduling. Students can be invited to join a class through a private code, or be automatically imported from a school domain. Each class creates a separate folder in the respective user’s Drive, where the student can submit work to be a graded by a teacher. Mobile apps, available for iOS and Android devices, let users take photos and attach to assignments, share files from other apps, and access information offline. Teachers can monitor the progress for each student, and after being graded, teachers can return work, with comments.
