Using Classroom with Your LMS
If a teacher is already using a CMS/LMS, this is not exclusive of Google Classroom. If a teacher is using Google Documents then Google Classroom makes a lot of sense. The teacher can build their content in their CMS/LMS. Directions, embedded videos, instructional elements can be in the CMS/LMS like they always have. Unlike Google Classroom, the CMS/LMS is designed to create content within the system. Where Google Classroom enhances this experience is the ease of distributing documents and collecting documents (particularly Google Docs.)
In the directions of their CMS/LMS module, teachers indicate to go to Google Classroom to find resources. Hyperlinking to Google Classroom where the link opens in a new tab aids in students easily accessing Google Classroom.
Sharing Google Docs through Google Classroom rather than the CMS/LMS ensures that the sharing rights are correct. Frequently documents are accidentally shared as private and students can not access the document, causing frustration. Google Docs attached in Classroom are automatically shared with the students, eliminating this frustration. The same is true for students submitting work. The teacher is automatically shared on any documents the student submits.
