School-to-work skills.
Engineers are motivated to learn when they solve interesting relevant problems and acquire professional skills. The interactive guided problems lead students step-by-step through a complicated procedure so they synthesize the problem-solving process and ultimately arrive at a physically significant and satisfying result. The problems in this textbook come from a wide range of engineering including aerospace, robotics, bioengineering, computer graphics, automotive, machine design, and controls.

Spaced repetition is a key to success.   William James (1899)
"You now see why “cramming” must be so poor a mode of study. Cramming seeks to stamp things in by intense application immediately before the ordeal. But a thing thus learned can form but few associations. On the other hand, the same thing recurring on different days, in different contexts, read, recited on, referred to again and again, related to other things and reviewed, gets well wrought into the mental structure. This is the reason why you should enforce on your pupils habits of continuous application."
