HEVs offer excellent potential for reduced emissions and lower energy usage.Three major objectives have driven the development of the GATE graduate program: First, is theestablishment of a laboratory environment that includes computer workstations for design andanalysis, data acquisition and control hardware, a hybrid powertrain dynamometer test cell and achassis (vehicle) dynamometer. Second, is the development of two new courses (one entitled HEVEnergy Analysis of Hybrid-Electric Vehicles: and the other entitled Modeling, Simulation andControl of Hybrid Electric

The faculty at PurdueAnderson has spent considerable resources researching and developing instructional methodsthat produced good results with adult learners. However, instructional methods that have provensuccessful with non-traditional students have been less successful with this new influx oftraditional students. The faculty revisited their initial research and the assumptions theydeveloped about traditional and non-traditional learning in an attempt to identify methods thatwould produce good results for both groups of learners.II.

Students designed, implemented andtested computer based projects in an interactive, team oriented approach.CprE 182X met once a week for 2 hours and we spent most of the time working with the robotsand providing support for the other courses the students were taking.

In this paper, we describe an attempt toengage students in the development of science activities for lay science students in twodifferent non-threatening ways within a traditional classroom lecture format. The first isby means of a design project of a science laboratory for lay science students in anengineering graphics design course. The second is by means of student-centeredinteractive-engagement methods in an introductory physical science course to promoteconceptual understanding in

Specific topics and how they are implemented into the design process include: economic analysis and time value of money, optimization techniques, statistical methods, and the design of experiments. One or two major design projects are required each semester. Typical activities have included: the construction of a Pitot tube which would mount outside a car window to measure velocity; the design of an orifice plate fluid flow transducer to measure flow velocity in a pipe; the design and implementation of a strain gauge laboratory where strain gauges measure deflections on a golf club, a cantilever beam, and a pressurized can.

A laboratory or machine shopshould have the instrumentation and machines to provide significant hands-on experience for students.

Errors have standarddeviation equal to instrument accuracy and have a zero mean. In the first case it wasassumed that resistance and temperature could be measured with uncertainty of 1miliOhm and 0. 1 °C respectively. To more realistically portray the experiment, tenmeasurements were taken at each temperature point [-30 °, 0 °C, 50 °C, 100°C]. This isthe level of accuracy easily achieved in a student laboratory.
