They believe that learning involves taking notes, memorizing facts, and later depositing facts on exams. Multiplicity (subjective knowledge). Early Multiplicity: There are 2 kinds of problems: 1)those whose solutions we know 2)those whose solutions we don't know yet. Student's task is to learn how to find the Right Solutions Late Multiplicity: Most problems are of the second kind; therefore, everyone has a right to their own opinion; or some problems are unsolvable; therefore, it doesn't matter which (if any) solution you choose. Student's task is to shoot the bull. (Most freshmen are at this position
Course at AAMUAbstractThe Accreditation Board for Engineering and Technology (ABET) Engineering requires thatgraduates must have demonstrated abilities listed in ABET Criteria 3(a-k). To ensure theattainment and quality of these outcome based mechanical engineering program criteria,faculty needs to develop an inclusive direct assessment process at course level to evaluatestudent learning related to the overall program outcomes. This paper describes a procedure inthe Mechanical Engineering Department at Alabama A&M University to improve teachingtechnique for outcome based courses. Assessment methods and results were discussed.Examples in teaching of Fluid Mechanics class are discussed in detail.IntroductionABET [1] requires that Mechanical

In 2003, after several revisions and input from the abovementioned groups, a set of six educational objectives was developed with the inclusion of theprimary aspects of the current feedback process. The future implementation of the PRS toassess the Program Educational Objectives will be discussed later in the article.The program outcomes are derived and judged based on the ABET criteria and specialrequirements for the Mechanical Engineering Degree. These outcomes are consistent with theProgram Educational Objectives and the University Mission. Table 1 presents the mechanicalengineering program outcomes.

Traditionally, the course was taught by standard method of teaching referred to as “chalk-and-talk” style. Recently, a great deal of attention has been directed toward teaching methodscollectively called “active learning” methods. Research studies evaluating student achievementhave demonstrated that many strategies promoting active learning are superior to lectures in thedevelopment of students’ skills in thinking and writing.1 Furthermore, cognitive research hasshown that a significant number of students have learning styles best served by pedagogicaltechniques other than lecturing.2-4Heat transfer
University (ASU) has integrated these skills intothe various courses within the engineering curriculum. However, recent assessments of theCapstone Design Course indicate that seniors need even more opportunities to gain these skills.In addition, the Dean of the Engineering School directed departments to have a course primarilyfocused on engineering business practices such as ethics, finance, and entrepreneurship. As aresult, MAE has created a new senior-level course called “The Engineering Profession”.This paper (1) discusses course development, (2) summarizes the course content, (3) describesinitial implementation results, and (4) makes recommendations for course improvement.Initial Course PlanningPrevious and current department vice-chairs began

The Capstone Design course uses theknowledge learned by the students in various academic courses, and trains them how tocomplete a project as an engineer utilizing that knowledge. It also teaches the student to workeffectively in a team, which is one of the top requirements of Best Practices for new B.S.graduate engineers by industry. By preparing the students to be successful engineers, theCapstone Design course improves student retention and will help to increase the percentage ofminority black engineers in future.1.

whilst robust does not always work but even in failure thereare often valuable insights into what the true first order contributors are and also the nature ofoften overlooked component interactions. In recent years a ‘watershed’ situation has come about with the advent of ever morepowerful engineering application software. Whilst software per se is not new, it has evolvedfrom being coded by the engineer end users themselves or programmed very specifically forone application into a whole new ‘beast’. Modern software packages require a largeraudience and more user friendly features if they are to make the return on investment neededfor a commercial enterprise. To wit packages demonstrate the following :- 1. Generality of application. E.g. A
Integrating Applications in the Teaching of Fundamental ConceptsIntroductionStudent retention through to the successful completion of an undergraduate degree in engineeringis of increasing concern to educators, policy makers, and, of course, students. It has beenestimated that only half of those entering an undergraduate engineering program go on tocomplete the degree.1 This is particularly low when one considers that the bar to enter anengineering program is often higher than for other programs.2 By 2007, Dean, Anthony, andVahala reported that the retention of engineering students had become a major undertaking formost institutions.3 As one of the largest engineering disciplines, awarding 21% of the 2007engineering bachelor’s degrees,4 retention is
determine the minimum base circle radius for given followermotion without undercutting. In this work, several optimization techniques have beenimplemented into the CamDesign program to calculate the optimal radius of curvature.Subsequently, the undercutting condition for each design is evaluated, and if the result ispositive, optional preventive measures are recommended to the user. For example, the programmay recommend both an increase of the base circle radius and decrease of the roller diameter.Fig. 1 shows a typical undercutting condition in which a part of the cam profile forms a fish tail.In practice, it is not possible to manufacture an undercut in a planar mechanism. Undercuttingcan be assessed based on the value of the radius of curvature

Introduction and MotivationThe finite element (FE) method is a numerical procedure that is widely used to analyzeengineering problems in commercial engineering firms. It has become an essential and powerfulanalytical tool in designing products with ever-shorter development cycles6-8. At mostuniversities teaching all but the most basic FE theory and applications has resided in graduate-level engineering programs using a number of FE texts15-17. In the past consulting firms found

Moreover, CAE tools such as Solid Edge, Unigraphics®, I-DEAS®,ANSYS®, etc., are used to perform parametric design and finite element analysis of individualcomponents and simple mechanical assemblies. Integration of such tools into the engineeringcurriculum enhances students understanding of, and appreciation for the iterative and open-endedness nature of design problems. This paper describes the teaching and learning experiencesof including such tools in few example courses in mechanical engineering.

All too often studentsbecome frustrated by the bewildering task of trying to determine the real world relevance of thecourse. Typically, course curriculum is taught straight from a textbook like Ogata4 or Franklin etal5. Students memorize formulas, recognize patterns and regurgitate information during tests.Our primary objective was to inspire students to understand control theory by developing alaboratory experience for the course. Other objectives for incorporating the bioengineeringlaboratory into a controls course were to: 1) Describe how changing P, I, and D control gains will affect the

ABET has been putting increasingemphasis on direct measures for a program to demonstrate its achievement of program outcomesand educational objectives. In this paper, an approach for assessment of course outcomes usingdirect measures is presented. The knowledge and skills described by the course outcomes aremapped to specific problems on homework and exams. Throughout the semester the instructorkeeps track of the performance of each student on each course outcome. At the end of thesemester students receive letter grades as usual. But in addition each student receives a “score”on the scale of 1-to-5 for every course outcome indicating
limited to textbook experiences as these faculty spendtime working to develop their research. This has led to a gap between what universities areteaching, and what engineers are expected to know in industry.1 Engineers in industry spendmuch time working on complex system integration, yet few engineering graduates understandthis process.2 Reference 2 adds “the state of education in this country, especially in science,engineering and technology, has become a matter of increasing concern to many of us inAmerican industry.”In order to meet the needs of industry, Universities must place a renewed emphasis on teachingthe practice of engineering. In order to teach the practice of engineering, students must bechallenged to study the complex interactions
student may have difficulty understanding what a mathematical solution to a problem 2means from a practical point of view. If students are provided with the means to performexperimentation and to apply the theory to real world situations, this can only be expected to leadto a better visualization and understanding of the theoretical concepts. The simulation systemdiscussed here presents an attempt of integrating Web-based content and interactive multimediatechniques into the curriculum. The integrated platform provides an easy flow of data fromtheory to modeling and measurement, bridging the gap between theory and hands-on learning, asshown in Figure 1.

These approaches start from an original design in digital format, whileconventional methods, such as casting with silicone-rubber or alginate molds require at least arough physical prototype. Coating and finishing processes for RP models are also discussed.Background and IntroductionThe Mechanical Engineering Department at the University of Texas at Austin has been engagedfor 6 years in a comprehensive program to implement project-based methods throughout theundergraduate curriculum [1]. One element of this program includes wind-tunnel testing inparallel with the introductory course in fluid mechanics. The undergraduate fluid mechanics labhouses two wind tunnels, with 12"x12" and 24"x24" test sections respectively. Currently
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

Currentresults are also compared to a study by Robert E. Mates from the State University of New Yorkat Buffalo entitled a Survey of Undergraduate ME Programs, conducted in 1987. Theconclusions identify changes that have occurred in mechanical engineering curricula as theEC2000 assessment process has matured.IntroductionThis paper is a follow-up study to a preliminary study conducted in 2000 of selected mechanicalengineering programs to discern the impact of the Accreditation Board of Engineering andTechnology’s new Engineering Criteria 2000 (EC2000)1 on curriculum

Moreover, it aids in an ABET goal ofintegrating computer usage throughout the curricula. Several problems dealing with strength ofmaterials are discussed. The first involves spatially varying material
