over one semester and is a 3.5-credit hour course. The attendance policy isstrictly enforced, so students were present for essentially every class meeting. Thermal-FluidSystems I is an integrated study of fundamental topics in thermodynamics and fluid mechanics,and the course introduces conservation principles for mass, energy, and linear momentum as wellas the 2nd Law of Thermodynamics. Principles are applied to incompressible flow in pipes andturbo machinery, external flows, power generation systems, refrigeration cycles, and total air-conditioning focusing on the control volume approach. Laboratory exercises are integrated intothe course as is a comprehensive, out-of-class design problem. This design problem provides anopportunity for

Assessment instruments of the pilots include assignment rubrics, focus groups,surveys, and questionnaires. This paper includes some of the preliminary data collection andresults and issues encountered by the development team.IntroductionThe Ohio State University (OSU) is a Research 1 land grant institution.

not necessarily true formany students. To partially address this deficiency, few instructors: 1. Draw sketches of components on the board, use textbooks and internet resources to show them the pictures and videos of components either in good condition or those that have failed during normal operations or in service. 2. Bring real components (whether failed or in good condition) as educational aids to the classroom. This is not always possible as some components may be heavy to carry. Page 22.924.6 3. Divide students in small groups and bring each group in to a laboratory that contain machinery (for example pumps

It was used to supply hydrogen to agasoline engine to run the engine in varying proportions of hydrogen and gasoline. Afactory-built injection and control system, based on the injection technology from theracing industry, was used to inject gaseous hydrogen into a gasoline engine to boost theefficiency and reduce the amount of pollutants in the exhaust. A fully programmableNOS Launcher Progressive Nitrous Controller was used with the ability to controlinjection of a fuel based on engine performance parameters such as RPM and manifoldair pressure. The system was first tried out

Adjuncts typically are “offthe radar screen” of the Dean and Chair, hence receive minimal feedback except from students intheir classes. Adjuncts often have little authority to improve the laboratory/class they teach andmay not be included in curriculum decisions. Supto recommends that “every adjunct shouldhave a full-time faculty member assigned as an advocate and resource” but this often isn’t thecase1. Adjuncts are often left to fend for themselves.Departments and faculty may want to do an excellent job of teaching undergraduates, yet it isoften the lack of resources and not

as follows: The deformation and wave propagation should be uniform and uniaxial so that the strain rate and compressive stress wave could be determined accurately based on the technique introduced by Kolsky. The maximum strain rate of 5000 should be attained by the apparatus.The design constraints are as follows: Due to limitation of the laboratory space, the apparatus size should be limited to 2 meters in length. Due to budget limitation, the total cost of the prototype should not exceed $1000.Initial Design:As shown in Figure 2, the major components of a generic Split Hopkinson Pressure Barapparatus are as follows: Nitrogen Tank / Compressor is the pressure source that the striker projectile is provided in

Illustration of the fringe pattern on a loaded sample in the Stress-Opticon Kit [17] .The Stress-Opticon KitThe Stress-Opticon (SO) is the kit used in the photoelasticity lab. The kit is a unique pocket-size“photoelastic laboratory” designed for qualitative demonstration of photoelastic stress analysis,mechanics principles, stress concentration and the behavior of structural elements[17]. Theapparatus is shown in Fig. 2. When a specimen is loaded inside the kit, the polarizers allowvisualization of the fringe patterns that correspond to the pattern of stress distribution in theloaded sample.Assessment of Results and DiscussionDuring the quarter, the photoelasticity lab was conducted one week and the FEM lab wasconducted the following week.

model for the course. The “Thermo-Fluids 1” course became, tostudents, the 7-mission “Hunt for Energy and Power”. The same textbook was used in thenew delivery model as had been used previously; the same laboratory experiments wereundertaken by students, but students had a different approach to the workload.Throughout the course, students proceeded at their own pace, and completed 7 “missions”,each with 5 levels of performance. The first 3 levels were successively more complexanalytical problems. The 4th level was a lab report based on a moderately challengingopen-ended lab experiment, and the 5th level was an opportunity for the student to extend aconcept based on the content of the earlier lab experiment.

suspicious thatseveral students in his Thermodynamics-II were using textbook solution manuals to do theirhomework assignments. After advising students several times that they are not benefitting fromusing the solution manual and warning them that the University policy considers such usage asplagiarism, the instructor found a web-site address written on a note in his office. The note wasslipped under his office door by one of the students in the course. The web-site was hostingsolution manuals for 10 mechanical engineering, 10 electrical engineering, and five civilengineering courses. In addition, the website included laboratory reports for a materials coursein mechanical engineering. Apparently, the site was hosted and managed by one of the

A perennial problem that still has not been adequately solved is providingspace where students can store their projects in-process. The course budget for equipment andsupplies is $10,000 per year, and comes from student laboratory fees.IV.

People with this learning style are best at finding practical uses for ideas and theories. They have the ability to solve problems and make decisions based on finding solutions to questions or problems. In formal learning situations, people with this style prefer to experiment with new ideas, simulations, laboratory assignments, and practical applications.Assimilating The dominant
