The original fields were mathematics and the sciences and numerous problemsets have been developed in these areas.In the effort described in this paper, problems are being developed for the beginning class, EE188 Electric Circuits I, at Northern Arizona University. This class covers basic dc and ac circuits,and fundamentals like Ohm’s Law, Kirchhoff’s Voltage Law and Kirchhoff’s Current Law. Theemphasis is on circuit analysis, where the circuit and parameter values are given and the studentdetermines a given voltage, current, power, or other value

interdisciplinary and “newer” branches and technologies, such as bioengineering, nanotechnology, alternative energy, etc.; this coverage varies from site-to-site and is primarily at the discretion of the individual instructors. As a means of describing the course coverage, the assignments that contribute to the course grades for the students will be discussed. The assignments can be divided into four general categories; those involving (1) a laboratory activity, (2) communication skills (written and/or oral), (3) a spaghetti bridge project, and (4) the final exam. The four laboratory activities and descriptions are as follows: (a) Materials Testing Lab – using spaghetti of different thicknesses, exercises involving

same. The simplest expression of the design process is encapsulated in ETC,Express-Test-Cycle. 7 This methodology may be explained as follows: 1. Express : This phase encompasses concept generation – brainstorming, ideation, sketching, defining the problem. 2. Test : In this phase ideas generated are tested and vetted against specific criteria. 3. Cycle : New issues inevitably arise that must be addressed, requiring a return to the Express phase.Other approaches are equally valid, but ETC is useful to make the relationship between designand convergent/divergent thinking more transparent. In the Express phase, divergent thinkingdominates. When a small group of solutions arise that are deemed preferable

learning of machine design using MDT in a computer labsetting. The MDT is expected to have a major impact on student’s retention of classroommaterials. It has been observed by Kolb [1] that active experimentation leads to better than 90%retention of material compared to a 30% retention for reflective observations.Programming Rationale for the MDT The MDT has been developed using de facto numerical analysis software, MATLAB, bytaking advantage of its user-friendly interactive graphic user interface (GUI) and multipledocument interface capabilities. Development of the MDT using MATLAB was a meritoriouschoice for many reasons, since its versatile computational power, easy graphical user interface,and availability of numerous toolboxes have lead

Engineering EducationThe term ‘wiki’ is a Hawaiian word meaning ‘quick’, but the term is used here to refer to aspecific type of website. The definition in this case, taken from Wikipedia (www.wikipedia.org),is that a wiki is a website that allows visitors to add, remove, and edit content. It is frequentlyused as a collaborative technology for organizing information on websites. One of the mostcommonly cited examples is Wikipedia, an online encyclopedia whose entries can (normally) beedited by anyone using a modern browser such as Internet Explorer (from Microsoft), Firefox(from the Mozilla Foundation), or Opera (from Opera Software). Wikis are used forcollaborative or group projects for two main reasons: (1) they are easily modified (you do notneed

, although these reports had been completed several years ago, there were norecords of the assessments actually being conducted and no results available.In preparation for the next NWCCU accreditation visit, the college developed a template to beused for assessment plans for all academic programs. This template can be found in Appendix 1.The engineering technology faculty struggled to use the template both for the college’sassessment program and for ABET accreditation. Fortunately, the dean had attended an ABETTechnology Education Initiative (TEI) workshop and was somewhat familiar with theAssessment Planning Flow Chart1 created by Gloria Rogers to guide faculty through the process.It was that experience which guided the process for our

The introduced design and FE analysis projects areexplained.IntroductionWhile working in industry, the authors have had many opportunities to work on machine designand analysis projects with a number of junior engineers, who recently graduated from variousuniversities with bachelor’s degrees in mechanical engineering[1]. It has come to our attentionthat many of the newly graduated students are not very capable of tolerating ambiguity, dealingwith uncertainty and making assumptions and decisions during the design process. It seemsmany of these new members of the workforce are

About 5 years ago, the author conducted a thorough survey of modern technologyavailable and have identified LabVIEW software and data acquisition device from NationalInstrument (NI, Irvine, California) to recover the system partially based on experience offered byengineering education community (1-6). Since the original transducers and control valves arestandard devices used in industry, the main thing we had to do was to change the “brain” of thecontrol system and design the control loops that suit our needs.

student retention.IntroductionNorthern Arizona University has been exploring methods by which to recruit and retainengineering students into their undergraduate program. Two of the Mechnaical Engineeringfaculty have recently been engaged in modifying a freshman CAD class with these motivationsin mind. They are implementing “Rapid Prototyping” (RP) into the ME 180 Freshman CADclass. This paper will document the work in progress on this effort to date.RP is the process which converts a CAD model into an artifact or product.1 This process hasbeen used increasingly over the past two decades in engineering firms to produce first-articledesigns. Advantages of using RP machines over using tradition fabrication methods includereduced scrap, less skilled

By hand via the textbook method.Upon completion of all three methods, the consensus of the class was that while Method1 was the most time consuming, it was the most rewarding, as the students were able tounderstand how each value of their design was calculated, and how it related to theunderlying HCM traffic flow principles. Method 2 was the path of least resistance,however it is believed that the value of the software was only truly appreciated after thestudents were forced to work through the methodology by hand, as the software is littlemore than a calculation tool; it is not a design interface.
