These materials are used as part of an active learning course, and the interplay between in-class activities that allow students to explore and discover ideas and a more formulaic study of the necessary computations is important. Each chapter has suggestions for active learning problem-solving activities designed to develop higher-order thinking skills. The video lessons in the chapter sections address a second objective, the skill-building component of mathematics. Can you successfully carry out the calculations necessary to find answers to a variety of applications? Conceptual understanding of the material is important, and instructors are encouraged make use of activities that help students advance the computational skills developed in the video lessons.
