What a class is
A class brings a teacher and students together around notes, problems, apps and sets. It works like a set: content in sections, in the order you teach it, opened inside the class with the class's contents beside it. On top of that a class has members, announcements and a discussion that only its members see. Find your classes in My Hub > Classes.
Joining a class
Your teacher gives you a code such as K7Q2-M9XP or an invite link. Enter the code in Join a class (or in My Hub > Classes), or open the link and press Join. You can type the code in small or capital letters, with or without the dash.
- Direct classes let you in at once.
- Classes with a waiting room keep you waiting until the teacher lets you in; you get a notification then.
You can leave a class from its page with Leave, and join again later with the code.
Studying in a class
Open any note, problem or app from the class page: it opens inside the class, with previous and next and the class's contents and your progress on the side. Under the content, the discussion has two tabs: This note (everyone's comments on the note) and This class (only your class sees them).
Creating and running a class
Academics and editors can create classes with New class. Choose a name, a short description, a cover and two settings:
- How members join: direct, or a waiting room where you let each member in.
- Who adds content: only you, or every member.
Add content with Add content on the class page (search and sections, like a set), or with the + button of any note, problem, app or set, where your classes are listed under your sets. Arrange puts sections and items in order.
The code box on the class page shows the class code and the invite link with copy buttons. New code makes a new one; the old code and link stop working, members stay. You can turn the invite link off in the settings.
Members lists everyone in the class: let people in from the waiting room, remove members, and follow the progress table.
The content of a class stays public on Hub 4 Mech; what is private is the class itself: its list, its members, its announcements and its discussion.
