Read This Before Using the "Class" Template in Microsoft Teams
/It's unusually difficult to explain why a Microsoft Team should not necessarily be created as the type labeled "Class" despite using it for highered-- especially when you conduct your course with additional platforms like a discrete LMS.
I use "Other" to simplify the interface for my students because if I were to use "Class" tabs like "Class Notebook", "Assignments" and "Grades" would appear, and these could only confuse my students since my content is in Brightspace ("eCentennial" at my college).
These additional tabs are tricky (or impossible) to hide. (I gave up on my Google research on the topic.) Whether or not these appear for you might depend on how your O365 IT admins have configured Teams for your institution.
Why do I bother to set up a Team? I feel it's more convenient for live video classes compared to the option I have through Brightspace (Virtual Classroom/YouSeeU/Bongo), and the chat function on Teams -- especially how it works on mobile -- is superlative. On Teams, it's also easy to combine groups of students that may be "uncombinable" in Brightspace owing to their having been enrolled in sections that pertain to different course codes for administrative reasons (i.e., same course in different programs).
