Actual Parts and Operation Video of a Harmonic DriveLaboratory ProjectsThe hands-on laboratory sessions consisted of two different types: weekly lab projects andcourse projects. There were ten weekly laboratory projects that consisted of two portions. Thefirst portion covered the description of the project including objective(s), required parts and partdescriptions, a wiring diagram, a sample program, and step-by-step tutorial instructions attachedin appendices. The second portion required the student to apply the knowledge

(1996) who categorized problem framing activities into(1) major principles and concepts that are relevant to the problem, (2) justification for includingthose principles and concepts, and (3) a procedure that can be applied to find the solution, wedefined the following categories based on initial data obtained from the Smart pens whenstudents solved statics and thermodynamics problems. Our protocol for problem framing wasdefined

Be able to demonstrate proficiency in the Portuguese language (in oral and written form) b. Be able to explain and recognize the cultural differences between Brazilian and U.S. engineers c.

thequiz format is that it will help student learning by (a) prompting students to keep up withmaterial as it is being taught in class and (b) reduce text anxiety / pressure on the students, bydistributing the evaluation into smaller parts. Each quiz is worth 11% of the grade in the QuizMethod, and each examination is work 27.5% of the final grade in the Examination Method. Bymaking each testing instrument worth a lower percentage, it is thought that students will feel lesspressure when taking each quiz. However, this may also reduce the level of effort that studentsplace on preparing for each quiz. In addition, the Examination Method may prepare studentsbetter for the longer (2 hour) final examination, although students should be familiar with

While these two issues are intimately connected, they are oftendecoupled.9 These problems remain intact, as evident by the continued poor performance ofengineering students in thermodynamics, Fig. 1. This strongly suggests that either a) theattempted solutions did not address the problems, or did not treat the root causes, or b) thesolutions that worked, or worked partially, were not adapted by a sufficiently wide population ofuniversity instructors such that a clear improvement in students’ performance at the nationallevel is achieved. None of the attempts seemed to be comprehensive- each targeted few certainconcepts and/or principles.Common engineering thermodynamics textbooks have not been affected by the incrementalsuccess of some of the

Substantial reformative progress on a broad scale has been made since EngineeringCriteria 2000 was first introduced as an ABET initiative designed to make step changes inengineering education6. It recommends assessment metrics designed to assist programs withcontinuous improvement. Commonly, Criterion 3 – Program Outcomes and Assessment, isdiscussed. According to ABET, engineering programs must demonstrate that their graduateshave: (a) ability to apply knowledge of mathematics, science, and engineering, (b) ability to design and conduct experiments, as well as to analyze and interpret data, (c) ability to design a system, component, or process to meet desired needs, (d

summer sessions, but not all. In the last two years morethan one section of the course has been offered during fall and spring semesters. Figure 1displays the percentage of grades of A+, A, A-, B+, B, B-, C+, C and C- (ABC rate) assigned bythe instructors for each section during this period. It should be noted that until fall 2011, thegrading scales did not include “+” or “-” letter grades. In Fig. 1, the instructors are identified asInst-1 through Inst-9. An examination of grade distributions shows that there are smallvariations in passing rates for a given instructor from semester to semester. A higher passingrate for an instructor for one semester may be due to an uncommonly good pool of students. Thegrade distributions in Fig.1, however

Maxwell’s Reciprocity TheoremMaxwell’s reciprocity theorem is a fundamental theorem in solid mechanics and is valid in thelinear elastic region. Referring to figure 6, this theorem states that if a load is applied at point Bon a specimen and the deflection is measured at point C, then the load is moved to point C anddeflection is measured at B the two deflection values will be the same. One of the most importantapplications of this theorem is the symmetry of stiffness matrices in finite elements method. Dueto this symmetry, only almost half of the elements of these matrices need to be

The initial interviews were conducted on lesson six and theclosing interviews were conducted on final lesson of the course. The instructor did not attend thefocus groups to prevent the possibility of perceived or actual bias during the course. For eachgroup, two groups of 4 students each were interviewed for about 30 minutes, using the scriptattached in Appendix B as a guide to the discussion
the students felt more confident that they could complete a more complexrobot. Overall, student’s self-reported knowledge of servos, motors and using manufacturingequipment increased based on survey results. The activity described in this paper has had a largeimpact on overall manufacturing confidence and course outcome for students.IntroductionUndergraduate mechanical engineering education usually places a high priority on designexperience. This is partly driven by the requirements the Accreditation Board for Engineeringand Technology (ABET) sets for engineering degrees1 . ABET criteria (a) through (k) includedesign explicitly, especially through criteria (c) and (b). The ABET criteria also implicitlyinclude design through requirements for
