the maximum moment along a shaft is important to identifythe critical point of the shaft for the maximum stress. However, many students have troubledrawing these diagrams. This animated FBD is intended to help student understand the processby showing the progression from one end of the shaft to the other end.FBD in a gear trainIn an earlier paper5, the author has given several examples on how to determine the direction ofgear forces of different types of gears.

In the 21st century, the country’s need for a world-leading STEM workforce and a scientifically, mathematically and technologically literate populace has become even greater, and it will continue to grow – particularly as other nations continue to make rapid advances in science and technology”.1 Although STEM plays a significant role in today’s global society, a December 2014 surveyby YouGov for IEEE shows that young adults, especially in the United States, seem to overlookthe value of STEM subjects.2 Table 1 shows the results of that

This paper discusses and examines a novel pre-college STEM interventionthat occurs at a technical engineering research conference. The intervention consists of a mini-workshop that has six components: (1) an introduction of graduate student mentors, (2) a generalintroduction to the engineering field of Smart Material and Structures through a PowerPointpresentation and live demonstrations of smart materials, (3) a low-cost design and buildengineering activity that uses smart materials to demonstrate the applicability of the field

This is different from the collaboration required of routine work.Students in these types of projects cannot simply subdivide the projects into smaller individual,independent tasks that can be reassembled into a coherent whole as that is not the way in whichdesign happens.1 Design teams need to be able to leverage the individual perspectives andunderstandings of the team members to develop, as a team, a collective understanding of andrelationship between the interdependent components of their work.

The professionaldevelopment is designed to promote student-centered pedagogy among undergraduateengineering courses. The theoretical underpinnings of the advocated pedagogy are stronglyrelated to tenets laid out in How Students Learn 1. In general, the professional developmentencourages instructors to move their classrooms toward being environments where students havevoice, instructors are responsive to varying student backgrounds, and relevancy betweencoursework and real-world applications are made clear. In sum, these are considered student-centered pedagogical strategies.A goal of the IUSE project evaluation is to

We expect students to develop, from the prompt andthrough literature search, an appropriate set of specifications for their breathalyzer, a design ca-pable of meeting those specifications, and evidence to show that their design does so. We do notassess the project on device performance, as the learning objectives are concerned with the stu-dents’ ability to follow the design process, not their ability to build accurate breathalyzers.Results to dateFigure 1 (left): An example of a student-generated Pugh chart examining techniques for notify-ing the user they have exceeded the legal breath alcohol limit.Figure 2 (right): An example student-designed

Climate change is considered by many to be a defining issue of our time and,throughout our students’ careers and lifetimes, its importance will only increase. Since the onsetof the Industrial Revolution, human activities, and primarily our use of fossil fuels, has increasedthe concentration of carbon dioxide, a greenhouse, or heat-trapping, gas in the atmosphere bymore than 40%1. On our current emissions trajectory, carbon dioxide concentrations may triplecompared to pre-industrial levels by 2100.

For example, three ways in which the institution can foster identity formation asan engineer are: (1) program admission criteria, coursework, etc. (institutional identity), (2) co-ops and internships (self-identification through exposure to the norms and values held byprofessional engineers), and (3) communities of practice (recognition by other in-group membersas a professional in the field)12,13. Co-ops and internships contribute to students’ desire tobecome an engineer14, retention and work self-efficacy15, and higher starting salaries and thepotential for a job offer by graduation16.

After afew weeks adjustment, however, teams started to make effective use of them.Case Study FindingsThe deliverable success rates of design teams as determined by faculty are reported in Table 1. Aproject was determined to be a failure if it did not meet the needs of the client in any substantialway and if no groundwork was established for future projects. If the project laid the groundworkfor improvement, but still did not meet the needs of the client, the project was identified asmitigated failure (e.g. a project with core work worth building upon by a design team in thefollowing semester).

This paper analyzes asmall portion of the data from 65 participants in order to better understand (1) participants’motivations for applying to a residential computing camp, (2) participants’ access totechnological tools and education prior to the camp, and (3) participants’ desired access tocomputing education at the end of the camp.

Ethicseducation should therefore encompass both microethical issues and macroethical issues.Microethics has been defined as “ethical decision making by individual engineers and theinternal relationships of the engineering profession” while macroethics has been defined as “theprofession’s collective social responsibility and the role of engineering in societal decisionsabout technology.”1, pg. 68 The various professional codes of engineering ethics are focused onmicroethical issues, including designing for public safety, whistle-blowing, conflict of interest,and integrity of data. Macroethics moves into a broader

Thechallenge then lies in the hands of the teachers in the middle and high school classrooms thatmust present concepts that are somewhat unfamiliar and unique to their initial certifications. For many teachers, the idea of lifelong learning and professional development arenecessary aspects to being a highly effective educator, but the programs chosen need to beinspiring and engaging. One of the issues with many professional development programs is thelack of inclusion of the entire group and a greater focus on individual achievements. This resultsin

Conversely, the ABET accreditation criteria (general plus program)define the minimum requirements for a program to receive accreditation. There will naturally bea gap between those two standards.For the cycle of change to be successful, the insights and lessons learned from the developmentof the CEPC should be communicated with the BOKTC and vice versa.

The paper will define the gap between (1) the BOK2 and (2) EAC/ABET accreditationcriteria (General Criteria plus proposed CEPC as well as newly revised General Criteria plusproposed CEPC) and make recommendations for closing the

These criteria are influenced, but not defined, bythe BOK. Finally, in addition to earning an ABET-accredited engineering degree, the first steptowards professional licensure is to pass the Fundamentals of Engineering (FE) exam3, which isadministered by the National Council of Examiners for Engineering and Surveying (NCEES).The relationships between the BOK, ABET accreditation and the FE lead to several questions:(1) Does the BOK adequately emphasize the knowledge, skills and attitudes required for successful preparation for the FE exam?(2) Similarly

Todays’ undergraduate enrollees are part of a new generation that hasbeen raised, not only socially, but educationally, on hands-on manipulatives, technology, andpush-button access. Their expectation of instant fulfillment is no longer met by traditionalmethods of teaching that emphasizes passive approaches to learning; rather, they not only expectbut, because of their prior experiences now require strategies that encompass visual stimulation,experimental/authentic learning, and community-based practices.1 Constructivist, constructionist,and action based learning theories

Regardless,there are many avenues of study with application to this project, such as research of energysources, optimization of power collection, and optimal storage of harvested energy. Onepromising source of harvestable energy is kinetic energy. Motion can be harnessed fromvarious sources and converted to electrical energy. References [1], [6], [14], [15], and [22]deal specifically with this process and the associated design challenges. In [14], the authorsdescribe a method of extracting energy from a piezoelectric element driven by mechanicalvibrations of varying magnitude. An expression for the optimal power flow for such anelement is derived and based upon that an energy harvesting circuit based is proposed. Thedesign in [14
