andcollegiate levels are poorly prepared to enter the workplace. Educators and business leaders recognize the need forextensive revamping of science, technology, and engineering curricula at associate-degree granting institutions tomeet the needs of business, industry, and government. The Just-In-Time (JIT) educational concept is designed to provide technical education on an as-neededbasis, meeting the requirements of students and employers. JIT uniquely combines education’s behavioralobjectives with technical curricula by integrating (1) basic core concepts, (2) the manufacturing line-balancingtechnique and (3) occupation-driven-based problems. This paper provides a description of the development of theJIT education model and a demonstration of

thenecessary skill acquisition. This paper discusses the structure and support of this course, and our experiencewith teaching it.1. BackgroundFalling enrollments and problems with retention of sophomores prompted us to examine our curriculum in1992. We interviewed students, looked at initiatives at other schools, consulted with industryrepresentatives, and debated strategy and tactics internally. Our conclusion was that we needed to improvethe students’ laboratory experience and integrate it more closely with lecture material. In that way, we feltthat we could provide stronger motivation for the lecture material and also reinforce it through immediateapplication.There has been a trend at the University of Colorado towards a separation of lectures

Processes (3 units, Lee/Lab) 2A description of the above courses can be found in Ref. . Because of the wide spread applications of mechatronics technology to various industries as mentionedabove, developing a complete mechatronics curriculum that would cover applications in all these industries bya single institution is neither possible nor realistic. Consequently, the taskforce developed a three-pillar concepton which its funding proposal to NSF was based. Pillar 1 is the fundamentals of mechatronics, Pillar 2 involveshands-on experience, and Pillar 3 relates to the application of mechatronics principles to local industry. Thisthree pillar approach is readily adaptable by other

software as a learning tool. The simulation model is based on the process descriptionshown in the attachment.Sample ProjectConceptually the experimental design problem can be expressed as a function y = f ( x1, x2, ....., xn)where y is the response variable and xj are independent variables for j = 1, 2, ...,n. The objective is to find thexj values that will either: maximize y, minimize y, or result in y being equal to a target value.Of course in reality, all the xj’s that affect y can almost never be enumerated. That is, n is often extremelylarge, and in fact, often unknown. To be realistic, then, a subset of the x's are chosen to experiment with,where those chosen are those thought to have the greatest effect on y. The combined effect

Several departments at each school are cooperating in this development, including: Mechanical,Industrial, Chemical, Electrical Engineering and Business. The curricula, consist of a progression ofmanufacturing/design courses, approximately one per term, and allows students to practice engineeringscience fundamentals in the solution of real problems. The key element in this approach is active learning -the combination of curriculum revitalization with coordinated opportunities for application and hands-onexperience; thereby erasing the traditional boundaries

In order to carryout the proposed ILI work, we needed to design and build a class 10,000 cleanroom withclass 100 laminar flow benches, including electrical, gas, water and chemical safety systems.

they went away from the lab. More time was wasted reconnecting the protoboard to the EVB each timethey wanted to work on it. They had to work on the assignments in the particular lab where the EVBs werelocated, which was also inconvenient for the student.THE SOLUTION Our solution to these problems was the 68HC11 EVB Portable Lab Unit. It consists of a 68HC11 EVB,power supply, breakout board, protoboard, and storage space for a wire kit, power cable, serial cable, logicprobe, and a few small tools. It is completely self-contained in a rugged case, and is quite portable. Itmeasures 14” x 10” x 6” when closed, and weighs about 12 lbs. A picture of the Portable Lab Unit is shownin Fig. 1.
