In 2018, Google introduced a major redesign to Classroom. In 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 of the same year, it became possible for any personal Google user to create and teach a class. Also in 2015, Google integrated Google Calendar into Classroom for assignment due dates, field trips, and class speakers. In 2015 Google announced a Classroom API and a share button for websites, allowing school administrators and developers to further engage with Google Classroom. It was released publicly on August 12, 2014. Google Classroom was announced on May 6, 2014, with a preview available for some members of Google's G Suite for Education program. Teachers can monitor each student's progress by reviewing revision history of a document, and after being graded, teachers can return work along with comments and grades. Assignments and due dates are added to Google calendar, where each assignment can belong to a category or topic. Each class creates a separate folder in the respective user's Google Drive, where the student can submit work to be graded by a teacher. Teachers can create, distribute and mark assignments all within the Google ecosystem. Students can be invited to join a class through a private code, or automatically imported from a school domain. Google Classroom integrates Google Docs, Google Sheets, Google Slides, Gmail, and Google Calendar into a cohesive platform to manage student and teacher communication. As of 2021, approximately 150 million users use Google Classroom. The primary purpose of Google Classroom is to streamline the process of sharing files between teachers and students. Google Classroom is a free blended learning platform developed by Google for schools that aims to simplify creating, distributing, and grading assignments.
