Teaching pre-calculus students electrical engineering principles using low cost hardware

Using low cost hardware and the Visual Basic programming language, the authors have developed teaching modules which can effectively introduce basic science and technology principles at several levels from high school to freshman Electrical Engineering. They have tested these methods in a NSF sponsored course designed to teach high school teachers how to introduce science and technology to their students. To illustrate how the software tool and inexpensive hardware can be used to aid learning and teaching electrical and computer engineering concepts in the classroom, the authors present example experiments
