We assigned the homework to students through implementing failure theories in specific close-end problems. Students were required to extend these concepts in their open- ended design projects.The Part III: The design of mechanical elements included the following topics: Typical machine elements including: bolts, shaft and key systems, gearing theories, spur gear, and bearings. It was well known that the design of typical machine elements were not the simple application of the stress/ strain theory discussed in the mechanics of materials but rather the application of design procedures.

It was like an one-stop service for a new instructor so that s/he can save a lot of time finding the right people to ask and avoid mistakes, which eventually cost students dissatisfaction I found it extremely helpful! I had no experience on any of the topics we discussed about, except sexual harassment.

that each program must demonstrate that their graduates areachieving the stated PEOs, but since 2012 the evaluation of PEOs are no longer required,However, criterion 2 still requires that the PEO,s must be reviewed periodically, to ensure thatthey are still consistent with the institutional mission, and the program’s constituents’ needs. Inthe most recent review, with consultation with various constituencies of that included theIndustrial Advisory Board and students, minor modifications are being made to the PEOs. Therevised PEOs are presented below: The Mechanical Engineering Program prepares students to attain the following program educational objectives a few years after graduation:1.

This norm particularly involves a lecturer’sdiscretion on how a class is organized along with how the student interactions in a class takeplace. The interactions here are defined by a debate, student to student discussion, student tolecturer discussion and so forth 3. Such interactions play an important role in quantifying &analyzing if the goal of improving a student’s knowledge is achieved. Over the past few years,current trends are being observed in stimulating various interaction patterns among students andlecturers in an educational setting

essentialcomponent of the student outcomes that must be assessed and evaluate and result be used as aninput for continuous improvement of engineering programs [1]. In most undergraduate engineeringcourses, students are assigned to research or design projects. These typically include the capstonedesign course(s) and some other upper division courses in the program. In large classes, studentsare either encouraged or required to complete projects in groups consisting of several teammembers.Formation of design teams and assigning grades to individual team member is a challenging taskfor the instructor. Some instructors have had students take personality tests to help place studentsinto balanced groups [2]. In one study the design formation methodologies were

During a test flight, the test pilot has set the engine power at 50,000 Newtons, whichcauses the 20,000 Kg aircraft to attend a cruise speed of 250 m/s. The engine throttles are thenset to a power level at 80,000 Newtons, and then the aircraft begins to accelerate.

: Knowledge,Comprehension, and Application (see Table 2). During the 1990's a new group of cognitivepsychologists, led by Lorin Anderson, updated the taxonomy and modified the form of thesethree categories to Remembering, Understanding, and Applying. Lower order cognition isadequate for memorization and for following simple procedures.Some types of learning and understanding require more than rote memorization of facts orsimply following directions. Cognitive activities such as analysis, synthesis, and evaluation aremore complex, and open ended. There can be many “correct” solutions (as well as many wrongones). Whether or not a solution is “right” might depend on the specific context. Bloom referredto these functions as “higher order cognition.” In
