These are not interactive lessons and serve only as a basic theoretical review and reference. Interactive Examples are interactive lessons, which usually contain graphical illustrations. They give the student an opportunity for hands-on exploration of a mathematical concept, for example, a function and its dependence on numerical parameters. In some cases, when it is helpful for understanding, Interactive Examples use animation of parameters to dynamically illustrate this dependence in a certain parameter range. Drills are collections of interactive problem-solving lessons which provide the student with an opportunity for evaluation and meaningful control of the learning process.
Drills also serve to build problem-solving skills.
The problems which the system generates in the Drill section of a Basic Block correspond to the subject matter covered in the Concepts and Interactive Examples sections of the Basic Block. The system accepts answers to the problems as input from the student. The student may check his or her answer and if it is incorrect, may give and check a new answer an unlimited number of times. The student also has the opportunity to view the correct answer, and in the case of more difficult problems, to obtain a full solution. Tests contain problems associated with the different chapters and topics of the product.
