However, it is not the principal learning environment. The Lesson book provides that information. However, learning itself takes place primarily in Activities. Activities are initiated by students at their own command. Nothing happens in AS unless the student requests it.
Activities are brief, focused, and repeatable.
As a result, each student moves at his own pace, working with Activities when ready and repeating them as needed. ActivStats deals with one concept at a time. The student's understanding of each concept is solidified before she moves on to the next one. Each Activity deals with a single concept or a few tightly related concepts in a single, consistent way. This approach helps students to fit each new idea into their growing understanding of statistics.
