speed.5. Simulation-Based ApproachWith the systems approach in mind, it is desirable to supply students with a tool to aid in thestepper motor selection and analysis process. The most efficient approach would be to provide acomputer simulation program that allows students to exercise a motor under conditions it wouldbe subjected to in a real-world application. The program should have a number of componentsfrom which students can select. A system designed by students would be put through a series oftests to quantify certain parameters of motor and circuit performance. Some of the parametersinclude starting torque and current, running torque and current, holding torque and current,maximum rotation speed and maximum duty cycle limit among others.A

The project needs a clear beginning and end, but it may be part of a larger problem.Clients are important as they simulate what happens in the real world and are more likely to givestudents problems which are open-ended. Students must produce a product which satisfies theclient. That experience of not having a correct answer is valuable. Also, working with a clientto define the scope of the problem aids the student in setting up a strategy to satisfy therequirements.

Second, they frequently made assumptions in the mathematical model that reflectedcontradictory choices of boundary points in the application of the mechanical energy balance.

In this way, real-world scientific inquiryand design is being practiced rather than following step-by-step instructions withoutforethought to why they are doing what they are doing.In the real world, scientists and engineers face open ended problems on a daily basis.
