thestudents involved obtained a thorough understanding of the engineering concepts and alsoimproved their soft skills, including team working, communication, and ethical and problemsolving skills. In-depth information about the evaluation results, course map and instructionalstrategy are provided in this paper.IntroductionEngineering curricula have experimented with multiple methodologies that expose students toreal-world problems. There are also deep concerns about American internationalcompetitiveness, amid indications that the U.S. is doing a relatively poor job at retaining andtraining students in the science, technology, engineering, and mathematics (STEM) disciplines14.Too many talented students get the impression from introductory courses that

already struggling to survive past their limit to afford energy and goods?Food for the hungry is another consideration. A strong outcry has erupted over the use of foodproducts (such as corn) for the production of ethanol to be used as a fuel.4 Thus, discussions ofboth ethics and economics should clearly be part of any decision to convert from the use of coalto alternative fuels in new designs for power plants.Project SpecificationsJunior MEs taking Thermodynamics are introduced to many of the fundamental principles (work,heat, quality, enthalpy, entropy, and efficiency) and components (piston-cylinder, throttle, nozzle,diffuser, compressor, pump, boiler, condenser, and turbine) which are incorporated into energyproduction.

. Also it demonstrates the type of studyand research required for realistic design.Besides a review of the mechanics concepts, perhaps the only two new topics that are usuallycovered in depth in a typical Machine Design course are: Fatigue Design and (Static and Fatigue) Page 15.1166.3Failure Theories as applied to the design of components (shafts, keys, couplings, fasteners,bearings, springs and gears). Engineering ethics is also introduced to the students.Course Learning Objectives (CLOs) 1. Develop, set-up, and solve mechanical component design problems based upon given data and requirements 2. Develop corrective action (define the

15.807.3 success in the ME curriculum. They primarily come from the areas of design, engineering professional skills (for example teams, ethics, and economics), and technical content used throughout the ME profession (for example statistics and curve fitting). Technical ME Topics: The technical topics covered are relatively broad, touching on content from thermal fluid systems, dynamic systems, solid mechanics, as well as some other typically non-ME areas. There is some flexibility in these topics, allowing the lecturer to draw upon his/her own area of expertise.Student reaction to this course has been overwhelmingly positive, as seen from end-of-coursesurveys. These surveys place the laboratory section of

number of countries. The United States and Canada possess the highest energy consumption per capita. A number of reasons exist for the high energy consumption per capita in the United States; among the reasons are (1) historically cheap energy, (2) low population density, (3) large area, (4) historically an abundance of domestic energy, and (5) no ingrained ethic for conservation.

heard a story about aprofessor at another university selling solutions manuals online through eBay. While it would benice if all our students were perfectly ethical, it really is not reasonable to expect them not tolook at the solution manual when it is freely and readily available, and it is unfair to grade theproblems when part of the class already has access to the solutions and the other part does not.Since that time the author has picked homework problems from a textbook other than theassigned textbook (and of course not telling the students the source of the new problems).Textbook publishers are quite willing to send copies of alternative titles to instructors, so there isno shortage of sources for questions, and a different book can be

those mechanical aspects,and also introduces sensors, actuators and computer control of integrated mechatronic systems,again in the context of robotics. The integrated engineering topics introduced in ME 1000include: design methodology, mechanical hardware, manufacturing tools, spreadsheets, 3DCAD, Newton’s laws for linear and rotational motion, graphing and numerical techniques,statistical analysis, oral and written communication, teamwork, and safety. ME 1010 builds onthese topics and additionally introduces computer programming, electricity and magnetism,electronic circuits, economics, and ethics. These topics are introduced and reinforced in thevarious course components: lectures, labs, reading assignments, problem sets, a team

Design and execute and necessary experiments to confirm or verify analytical findings related to the building analysis. 2. The ability to design a system, component, or process to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability (ABET outcome c). i. Design and analyze alternate cooling systems for the Atheneum building. ii
