Chapter 12, Groups and Cohorts, shows you how to use groups to separate the students in a course. You will also learn how to use cohorts, or site-wide groups, to mass enroll students into courses.
Every block adds functionality to your site or your course. Chapter 13, Extending Your Course by Adding Blocks, describes many of Moodle's blocks, helps you decide which ones will meet your goals, and tells you how to implement them. You can use blocks to display calendars, enable commenting, enable tagging, show navigation features, and much more.
