NOTE: Due to a lack of administrative access, IT support for Google Classroom is fairly limited.
An alternative to Moodle, Google Classroom is a light-weight learning management system that offers some Moodle-like functionality in a Google environment (content sharing, discussions, quizzes and grade book).
Classroom offers the advantage of integrating easily with existing Google drive content, and faculty/students can create new Google Docs from within activities.
Not as robust a feature set as Moodle.
Available from the link at the right or via the Google App picker (upper right of window in Google Apps)
