Google Classroom is a blended learning platform developed by Googlefor schools that aims to simplify creating, distributing and grading assignments in a paperless way. It was introduced as a feature of G Suite 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, Gmail for communication, and Google Calendar for scheduling, and Google search to help with school projects. Students can be invited to classes through the institution's database, 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, for the student to revise and improve the assignment. Teachers can post announcements to a class stream, where students can comment.

Google claims that, as part of G Suite for Education, it does not show advertisements for Google Classroom users, and does not collect data or information for advertising purposes. This has been disputed. Google stopped scanning students' Gmail messages in April 2014 following privacy concerns, but the Electronic Frontier Foundation has twice, in December 2015 and April 2017, alleged that Google has broken its commitment to privacy, by gathering information without consent[citation needed]. Google has responded, saying that it is "confident" its tools comply with applicable laws and privacy pledges.

Google has there user to create and teach a class. 

Google Classroom ties Google Drive, Google Docs, Sheets and Slides, and Gmail together to help educational institutions go to a paperless system.

 Google Calendar was later integrated to help with assignment due dates, field trips, and class speakers.

Students can be invited to classrooms through the institution's database, through a private code that can then be added in the student's user interface or automatically imported from a school domain.

Each class created with Google Classroom creates a separate folder in the respective user's Google Drive, where the student can submit work to be graded by a teacher.

Assignments are stored and graded on Google's suite of productivity applications that allow collaboration between the teacher and the student or student to student. Instead of sharing documents that reside on the student's Google Drive with the teacher, 

files are hosted on the student's Drive and then submitted for grading. Teachers may choose a file that can then be treated as a template so that every student can edit their own copy and then turn back in for a grade instead of allowing all students to view, copy, or edit the same document. 

 Students can also choose to attach additional documents from their Drive to the assignment.

Google Classroom supports many different grading schemes. Teachers have the option to attach files to the assignment which students can view, edit, or get an individual copy. Students can create files and then attach them to the assignment if a copy of a file wasn't created by the teacher. 

Teachers have the option to monitor the progress of each student on the assignment where they can make comments and edit. Turned in assignments can be graded by the teacher and returned with comments to allow the student to revise the assignment and turn back in. Once graded, assignments can only be edited by the teacher unless the teacher turns the assignment back in.

Announcements can be posted by teachers to the class stream which can be commented on by students allowing for two-way communication between the teacher and students.

 Students can also post to the class stream but won't be as high of a priority as an announcement by a teacher and can be moderated. Multiple types of media from Google products such as YouTube videos and Google Drive files can be attached to announcements and posts to share content. Gmail also provides email options for teachers to send emails to one or more students in the Google Classroom interface.

 A Classroom can be accessed on the web or via the Android and iOS Classroom mobile apps.

Teachers can add students by giving students a code to join the class. Teachers that manage multiple classes can reuse existing announcements, assignments, or questions from another class. Teachers can also share posts across multiple classes and archive classes for future classes. Students' work, assignments, questions, grades, comments can all be organized by one or all classes, or sorted by what needs reviewing.

Classroom allows instructors to archive courses at the end of a term or year. When a course is archived, it is removed from the homepage and placed in the Archived Classes area to help teachers keep their current classes organized. When a course is archived, teachers and students can view it, but won't be able to make any changes to it until it is restored.

Google Classroom mobile apps, introduced in January 2015, are available for iOS and Android devices. The apps let users take photos and attach them to their assignments, share files from other apps, and support offline access.

In contrast to Google's consumer services, Google Classroom, as part of G Suite for Education, does not show any advertisements in its interface for students, faculty, and teachers, and user data is not scanned or used for advertising purposes.
