of simultaneous linear equations.Many students find solving three or more simultaneous equations difficult, particularly whenthey are written in symbolic form. Three examples drawn from an undergraduate systemsdynamics class are shown to demonstrate the process of solving simultaneous linear equationswith Maple. These examples can be used as templates for solving similar problems. Manystudents initially resist using Maple, since not all of them have had previous exposure. However,most students quickly learn that this modern engineering tool frees them from tedious algebraicmanipulations and allows them to accurately solve much larger and more significant problems.References1.

for corporate placement of student graduates,research funding or collaboration, design project opportunities, financial support and curricularadvice. These goals form a solid foundation for the industry-academic partnership. However, tomove to the level of a “strategic partnership,” a deeper commitment on both sides and longer-term thinking are required. If both the University and the corporate partner are committed,ABET related issues naturally arise. After all, the new EC 2000 criteria are based on outcomes,require dialogue with constituents, and call for data reporting on student performance in theworkplace.

As in thevirtual classroom shown in Figure 1, the discussion forum will form the fourth element of thevirtual laboratory for the geomechanics course.7.0 Conclusions and future workThis paper described the development of an online geomechanics course with a virtual rock lab.Several innovative approaches have been adapted for both the lecture and laboratory portions ofthe course, and initial trials with the online course have been very positive. The course willdebut in 2001 and at that time a complete assessment using student feedback will be made.Readers are encouraged to view some of the lecture modules that are now available on theinternet2.The advantages of

To determine the sheet resistivity, the 2400 source meter isused to force a current through the outer two pins of the Signatone S-301 probe head, whilemeasuring the resulting voltage on the inner two pins (see Figure 4(a)). After the application of acorrection factor to allow for layer geometry, a measurement in ohms/ is attained. The sheetresistivity is measured 3 times during the process; before field oxidation, after field oxide etch,and after diffusion drive-in. Each measurement is made in a dedicated region of the wafer. Thesemeasurements show the initial sheet resistivity of the wafer, the effect of oxide growth on dopedsilicon, and the proper execution of

Nearly all teams spend less than $50, and some are able to construct their waterheaters for less than $25.Testing is done with a portable setup that features a pump, rotameter, hot and cold waterreservoirs, thermocouples on the inlet and outlet lines, and a radiometer. Each group mustcalibrate the rotameter before testing their heaters in the sun, and this provides the students withan opportunity to perform statistical analysis (linear regression, standard estimate of the error) ondata that are relevant to them. Following their initial water heater test, each team must modifytheir water heater and retest.An important element of the laboratory sessions is technical
: student conferences.II. Walvoord and Anderson’s Assignment Centered CourseWalvoord and Anderson5 have noted that aside from the burden of grading written assignments,an even bigger problem is the inadequacy of instructor feedback on written work. Figure 1depicts a course in which students must wait for written work or exams to be returned beforethey gain access to instructor comments that might help them better hone their critical thinkingskills. By then, the student has likely lost interest; the “teachable moment” has been lost.6Walvoord and Anderson’s approach attempts to move the feedback stage earlier, into theclassroom, by placing on students the responsibility of gaining initial exposure to the coursematerial prior to the class meeting time

The fact thatPrinceton semesters are only 12 weeks long further compressed the presentation of this material.I tried to update the the architecture/microprocessor course by adding material on embedded com-puting applications. However, the course was too short for students to become truly comfortablewith any aspect of the material. As a result, I split the course into
extensive research on how chemicals are used and how they can be eliminated, reduced, or recycled. Industry is thus faced with hiring environmental engineering technologists and/or training its workforce. The Sinclair Environmental Engineering Technology program is designed to provide the necessary training. Courses such as SRM 151-OSHA 40 hour Hazardous Waste Operations, EVT 260 Treatment, Storage, and Disposal of Hazardous Wastes, and EVT 200 Environmental Waste Management (Pollution Prevention) are just a few of the subjects sought by industrial firms. Students, who enroll to take one or two work-related courses, often return to complete a degree program. Thus the Environmental Engineering

mid-July. This also permits our new freshmen and transfer students the time needed toreceive their final grade in college transfer courses and have their transcripts sent to ourOffice of Admissions for initial evaluation, before being forwarded to the appropriateacademic departments for evaluation concerning degree requirements.Prior to the student receipt of these registration packets, faculty and staff advisorsreceived numerous telephone calls from new freshmen and transfer students, inquiringabout the registration process and with specific questions about the transferability ofAdvanced Placement (AP), International Baccalaureate (IB), and college credits. Many ofthese calls were motivated because our new students had friends who were
very stable and showed some hysteresis. This led to overall frustration with theexperimental part of the laboratory.The instrumentation module required a considerable amount of planning effort. The lowcost data acquisition modules were limited in scope and required a considerable amountof experimentation. The software supplied was limited to slow computers and would notwork at first with higher speed processors. The manufacturers developed a softwarepatch that helped somewhat. Automatic triggering of the data acquisition would notwork and we had to implement hardware triggers to initiate data acquisition. All in althe effort was very useful and while not all students grasped most of the material, manylearned the methodology of making

Also, sincethe students were observed in two groups, it was assumed that both groups were academicallyequal.IV. LimitationsGoing into this study, it was known that time would be a constraining factor. The research wasto be conducted over a period of between one and two semesters. Another constraint was thataccess to the web could not be completely restricted to just the test group. There may have beena sharing of information among students. Another constraining factor was the possible difficultyof accessing the web site from an off-campus location. Students may have gotten a busy signal,or they may have had routing problems.

Jennings Department of Civil Engineering Case Western Reserve UniversityAbstract Between May, 1995 and August 1997 collaborators from seven Gateway consortiumuniversities worked to develop shared resource modules to help support EnvironmentalEngineering education.

class time. Thissecond revision was very rewarding, achieving a >95% attendance rate over the semester, andstrongly positive student evaluations. By making engineering design central to the class, studentmaturity and student interest were increased, and their educational needs better served, than inthe traditional lecture format. At the time of this writing, the third revision of the course isunderway. I am now distributing printed class notes to transmit technical information, and relyingon problem sets, quizzes, a semester long design project, and student initiated discussions toreinforce the material. Again, the non-lecturing, design focus of the course appears to beachieving high student attendance and interest. These experiences have

Furthermore, as of yet, no large-scale hyperdisciplinary course-ware has been developed although the initial coordination between departments has been madewhich has lead to an NSF proposal. Coordination between the United States Military Academy,Virginia Tech, and the University of Wales is also underway to extend the idea of hyperdiscipli-nary courseware to apply to different institutions and measure the effectiveness of hypermedia-based courseware.
