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

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.

Considering market conditions, student teams proceed by selecting a project to plan andthen designing a project control system for the project. This is accomplished by selectingmethods for each project activity and balancing the schedule and cost considerations. In Phase 1,students compete against their peers as well as the simulation’s virtual companies for award ofthe project. Award of projects is based on the team’s accuracy and proximity to the simulation’sinternal estimate. Teams that are not initially awarded a project for their efforts must continuewith
