student performance in a particular outcome whereas the final letter gradegiven to a student is an indication of his cumulative achievement which is computed using somesort of a weighted average (30% HW grade, 20% exam grade, 10% project grade, etc.).There are three basic requirements to implement this approach: (1) At the beginning of thesemester make a course plan including assessment, (2) Break down grading along courseoutcomes on the assignments/exams using a grade box, and (3) Enter scores into gradespreadsheet for each course outcome.For faculty who have teaching assistant support, most likely items 2 and 3 would be done bytheir assistant. The most critical thing is to have a good course plan at the beginning toimplement this approach
ofinstitutions have built experiments for various heat transfer experiments.[1-6] In some casesstudents have built heat transfer experiments as part of a design project and then used theexperiment in a thermal fluids laboratory course.[7, 8].We have developed an experiment in free convection for MECE 352 adapted from one used inthe Department of Mechanical and Aerospace Engineering at The State University of New Yorkat Buffalo (SUNY Buffalo) (with permission). In the experiment, students take directtemperature readings from a vertical heated plate using thermocouples and a LabVIEW DAQinterface. The convective heat transfer coefficient can be calculated from the temperature profilenear the vertical plate and compared to analytically determined values. In
theplan of action for the day and held discussions about team issues, like the research project andteam name.After snack time, the team moved to the classroom. The coach chose to partner the youth totackle the problems of the robot performance part of the competition. By partnering the children,the amount of time each student participated on the robot was their own choice. Typically, atleast one of the partners could concentrate on the problem designated, giving them a chance towork almost one-on-one on the problem. When neither partner could focus on the problem, littlewas accomplished, creating a challenge of directing the youth into working. Usually, the coach,one or two mentors, and a parent volunteer were present to supervise and refocus the
Squeeze Lab. This lab was derivedfrom a colleague’s research and development project with a manufacturer of drug deliverydevices. A controlled-dosage device was being developed to deliver a single dose of liquidmedicine into a child’s mouth. The device was operated by manually squeezing a bulb. It wasimportant to optimize the design so that the drug is delivered as quickly as possible but withoutgagging the infant. An important parameter is the force that a person applies to the device duringsqueezing. The students were asked to characterize the force applied to the controlled-dosagedevice by considering a population of college students (i.e., find the mean squeeze). Formotivation, the students were told that their results would be used by the

First year students work in teams ofthree to design a small projectile launching device equivalent to a child’s toy. Teams workthrough innovation and design processes of problem identification, goal setting, research,prototyping, evaluation, and reflection. Labs during the quarter provide students skills in solidmodeling and projectile motion and design documentation, but the final project requires them tosynthesize these lessons into a single product. Students design the device virtually inSolidWorks, evaluating assembly issues of contact interference and can conduct

allow for the synthesis and evaluation of amechanical system, as defined by Bloom’s Taxonomy4. To facilitate these higher level aspectsof the learning process, these kits provides the necessary mechanical parts in which a student hasthe capability to design and construct a mechanical system to perform a task or solve a problem.Advanced engineering courses such as ENGR 4100 – Machine Design could utilize the Page 25.790.7flexibility of the kits to accommodate individualized design projects. The VEX RoboticsDevelopment System also provides pre-drawn SolidWorks VEX parts that would allow for theCAD design of a mechanical system, such as the
disciplines such as law or business for a broader learning experience. In this case, the MS degree is usually viewed as a terminal degree. - The time to graduation is well-defined and consistent for all students. - Students may be selected into the program as late as their senior undergraduate year (depending on how many courses are allowed to be double-counted). - Advising, tracking and mentoring the student is easier.Programs that allow only the thesis option for the graduate portion of the BS/MS programusually have the following features: - The time to graduation varies depending on the thesis research project, the faculty advisor, and the student. - Students are often selected as early as possible (in the first year of
criteria, and Work in groups to solve complex problems.Objectives are achieved using a series of demonstrations followed by hands-on activities thatrequire students to utilize a specific set of tools in the drafting software over the first ten weeksof the course. The remaining time is dedicated to an open-ended project that requires groups ofstudents to design a mechanism to solve an engineering problem. The problem includes a set ofconstraints that must be navigated to be successful. Students are also asked to produce the partdrawings needed to construct the mechanism and use the drawings to create a prototype.ENGR 200The objective of this course is to produce students that can: Create software to solve engineering problems using both
projects that require problem solving. The main problem solved in the current case was to find ways to make the subject of statics more easily and more deeply understood.Prof. Mehrdaad Ghorashi P.E., University of Southern Maine Mehrdaad Ghorashi is a registered Professional Engineer (P.Eng.) in Ontario. In 1995, after receiving his first Ph.D. (on dynamics of structures under moving loads), Ghorashi joined the mechanical engineering Department of Sharif University of Technology as an Assistant Professor. In 2004, Ghorashi moved to Canada where he worked in Carleton University as a Postdoctoral Fellow. He also taught a few courses at Carleton for which he received the Best Professor Award from the Carleton Student
thatstudents do while watching the PPR media. It should be pointed out that in this class, in addition to thePPR media and in-class sessions, the students also worked homework problems, took quizzes and exams,and carried out a computational-based project. So a lot of hands-on problem-solving took place. But the“passive” nature of these technologies brings up an important question: what is the most effective way for Page 25.1412.3students to learn to work heat transfer problems or other engineering problems? There has been muchpublished regarding active learning and discovery learning, which derive mostly from the constructivistmovement in
amplifier. Wagner et al.8 reviewed the operational behavior of an eightday mechanical clock through mathematical models, numerical simulation, and computeranimation for dynamic system studies. A series of five laboratory and simulation experimentswere report by Burchett et al.9 which emphasize fundamental concepts in dynamic systemsincluding a swinging pendulum whose bob is located to offer maximum angular velocity.Delson10 discussed the use of a model clock project for students to analyze and fabricate apendulum and escapement wheel with integration into a clock11. In terms of K-12 audiences, theNational Science Resources Center developed the measuring time (life & earth sciences)curriculum model (grade 6) within the science and technology for
projects provide this in a significant way, but a capstone course provides onlyone experience with a particular project. It is valuable to introduce the idea in smaller ways,when possible. Reciprocating engines provide a good vehicle for tying together manyengineering concepts. All students are familiar, at least as users, with piston engines. Theirpracticality is therefore obvious. Thermodynamics, heat transfer, combustion, fluid mechanics,mechanism design, material science, strength of materials, and electrical circuits are all needed toproduce an operating engine. Seeing this connection directly can provide motivation for study ofthe individual subjects, and a realization that required courses are not completely unrelated.Goals and Integration
deciding what to cover in a course. Courses have been added to curricula to improveFE scores [4, 5, 6]. The technical content of several programs (typically general engineeringprograms at state universities) was selected from the beginning to cover the FE [7, 8, 9].This project arose in a new mechanical engineering program. My intention was to use the FEExam Specifications as a single simple source on what one might expect in a mechanicalengineering program. The FE also seemed like a straightforward, objective assessment. However,as I tried to develop learning objectives that comprehensively covered FE Mechanical content, Ifound it necessary to consult multiple sources beyond the Specifications. Furthermore, seeinghow competency is assessed on the
Picture This work is part of a larger project which spans multiple subjects and seeks to broadenunderstanding of STEM topics. This approach is meant to help both teachers and students,allowing for more innovative teaching and enhanced comprehension-based learning. The projectrecognizes that students learn in diverse ways, and attempts to appeal to those who learn bestthrough visual, intuitive, and engaging methods. It draws upon real-life experiences, as well asvarious STEM/STEAM examples and activities, and targets both an understanding andappreciation of basic concepts in STEM, including Physics/Mechanics, Calculus, Statics, ControlSystems, Digital Signal Processing (DSP), Probability, Estimation, and Computer Algorithms.The material can
promote a deeperconceptual understanding of integration with an interpretation of the sign and magnitude of theboundary work transfer using a P-v diagram.Examples of Assignments for Enhancement of Student Depth of KnowledgeIn teaching the first course in thermodynamics for many years, authors have learned that thereare certain areas that students struggle throughout semester. We routinely assign specialproblems or mini projects every semester to help students to overcome their struggle withunderstanding of fundamental concepts. (13,14) One area of student difficulties is the evaluation ofthermodynamic properties in the compressed liquid region. Almost all thermodynamic textbooksprovide compressed liquid thermodynamics property tables only for

The current focus of Dr. Wood’s research is the continued development of empirical testing methods using similitude-based approaches. This approach provides significant potential for increasing the efficiency of the design process through a reduction in required full-scale testing and an expansion of the projected performance profiles using empirically-based prediction techniques. Dr. Wood’s research also includes the development of micro air vehicle systems using innovative conceptual design techniques for current technology implementations, as well as futuristic projections

Studentswere given the option of using Excel, IHT, EES, or similar software for plotting the curves. Allstudents selected to use Excel to complete their assigned project. The main reason was theconvenience and the availability of Excel of student personal computers.SummaryThe application of Excel spreadsheet in solving one dimensional heat conduction problems wasdemonstrated through several examples. It was shown that Excel is a useful computational toolwhen the solution to problems requires (a) varying one of the parameters, (b) plotting the resultsof calculations, and (c) an iteration process.References1.

It will be important to maximizeparticipation in future data collection.These IAT results serve as students’ baseline engineering identities. As we revamp ourmechanical engineering program, what we learn will lead to a clearer understanding of thechanges that promote engineering identities, especially in women and minorities, and how suchidentities affect students’ sense of belonging in a program and their persistence in the major.AcknowledgementsThis project was funded by the NSF IUSE/PFE: RED grant #1730354.References[1] Y.-L.
