Web Based Learning Tools On Microprocessor Fundamentals For A First Year Engineering Course

We present two self-paced, web-based learning tools that introduce computer concepts by simulating a simplified computer we call the Fundamental Computer, and the more complex Lego Mindstorm's RCX processor. The learning tools were developed for use in the Introduction to Engineering Systems course at the University of Notre Dame. The course takes a multi-disciplinary approach to engineering, and two of four course projects involve the RCX. The learning tools expose students to what goes on under the hood of a computer, and, in conjunction with a physical laboratory project, give them a sense of working on a real workplace assignment. The Fundamental Computer is similar to the “File Clerk” explanation in Richard Feynman’s Lectures on Computation. The simulator for this computer can input and output values, perform basic arithmetic operations, and control the execution of a program, while the simulator for the RCX processor works for a substantial portion of the NotQuiteC programming language instruction set. Included in the learning tools are a set of reference materials that explain technical concepts, a Java, web-based simulator of each of the computers, and a set of step-by-step instructions for proceeding through the execution of some pre-written, demonstration programs. Both tools have been used by over 300 first-year engineering students who go on to major in various engineering disciplines. Because the learning tool is web-based, it is also available to any institution that wishes to use it. . In this paper we discuss our motivation for creating these tools and their implementation, as well as results from student surveys and suggestions for successfully incorporating web-based learning tools into traditional courses.
