Blocks are the sections that you see to the right and left of your class list (on your homepage) or the central panel containing class content. Commonly seen blocks are Navigation, Administration, Useful Links, My Coursework, My Timetable and Messages.
The blocks a student sees in a class will depend on what blocks are made available to you by the tutor/admin staff.
Docking a block will minimize it and 'stick' it to the left hand side as a tab. To dock a block, click the 
icon . To 'undock' it, just click on the tab and click the 
icon.
Undocked Docked To Undock
Minimizing a block will just make it smaller but it will remain in the same position. To minimize a block click the 
icon and to expand the block click the 
icon.
You can dock or minimize as many blocks as you like. Except the Administration block, which can only be minimized.
