Session 1247 Vacuum Systems Laboratory Development: Teaching More About Making Less David M. Hata Portland Community CollegeAbstractThe implementation of new associate degree programs in semiconductor manufacturingat community colleges across the nation has created a critical need for vacuum technologycourses and supporting laboratories. Unfortunately, few resources have been available tosupport technology-level courses in vacuum systems. This paper describes the results ofa two-year project to develop a vacuum technology course, implement a vacuum systemslaboratory, and provide

In the past we useda computer and LED panel in the classroom to show how to use software, with studentsdeveloping program use skills on their own using the Department’s computers. Departmentalcomputers were limited in both number and current technology. Programs are now on anetworked system, providing a better environment to manage software in terms of updates.Networked computers use a Window operating environment.

This would require a multi-meter,AC-DC signal sources, an oscilloscope, a prototype board, and RLC discrete components. It ispossible that given a very good video tape walk-through on all of the equipment and each of thelaboratory exercises, the student could learn something and that the equipment might survive.Should this plan be approached, considering the cost, the potential to teach electronics ismarginal. The opportunity to make mistakes in the presence of someone who can assist in therecovery from those mistakes is a necessary element of the hands-on-laboratory.

IfMET programs are to fulfill their mission of delivering students who are prepared to “hit theground running”, it is imperative that laboratory equipment reflect what exists in the real world.Students in an MET “Air Conditioning and Refrigeration” elective will benefit from exposure tothe building automation equipment that they will encounter during their careers.

To date, the laboratory has involved a total investment ofapproximately $126,000, three quarters of which has gone into equipping experimental stations.Support for the laboratory has come mostly from private industry and a private educationalfoundation (60% of total), but the early and generous commitment of university and departmentalresources was central to establishing the laboratory.

The importance of safety in the unitoperations laboratory is reflected in the course syllabus, which states the first objective ofthe course as:“Develop a constant awareness of safety in the laboratory so that all laboratory work iscarried out in a safe manner.” (Caspary and Ellis, 1997)The MTU unit operations laboratory provides an ideal setting for teaching process safetyand for preparing chemical engineers for safety in the chemical industry.

The modules are designed to teach students how to collect, analyze and interpret data toobtain design parameters for engineered processes or mathematical modeling of contaminanttransport in the environment. Each module contains concept, laboratory and analysis tutorials,videos of each lab, and an animated laboratory that can be used by the students to evaluate theeffect of different design and operational parameters.Students are expected to review the modules at various

INTRODUCTION To educate a new generation of engineers for the twenty-first century, engineering educatorsface many challenges such as the development of students’ ability in critical thinking, creativity,collaborative work, and communication. Laboratory education can play a pivotal role in attainingthese goals. However, due to the limitation of traditional laboratory teaching, its potential benefitshave never been fully realized. The problem becomes more acute if the laboratory course isequipment-intensive. Since students are usually not familiar

Of course it is still virtual, but it is a practical laboratory encounter forcourses that must enroll so many students.Other virtual devices that have been developed and used include a ball falling in a gravitationalfield, a satellite orbiter and a Bungy Jump simulation.Course materials can be found at the URL: http://www.cps.msu.edu/~cps131References1.

educational methods as “problem-based.”That is, learning how to solve problems is not the same as Problem-Based Learning.Indeed, many engineering programs have introduced “industrial” or “good engineering”practices into their laboratories. For example, the University of Missouri’s ChemicalEngineering department felt that their laboratory courses should encourage students to getresults while also teaching them to write concise reports. In short, lab should not onlydemonstrate theory. As a result, they replaced simple theory-based goals with “practical,industrial problems.”iii Although this change incorporated many of the ideas of the PBLapproach, it is learning through problem solving that defines PBL.

Photographs of specimens were takenwith a low magnification (40x) stereoscope in one of the MSE laboratories followed bypolishing.
