Effectiveness Of Drafting Models For Engineering Technology Students And Impacts On Spatial Visualization Ability: An Analysis And Consideration Of Critical Variables, Petros J. Katsioloudis, Jill E. Stefaniak

STEMPS Faculty Publications

Results from a number of studies indicate that the use of drafting models can positively influence the spatial visualization ability for engineering technology students. However, additional variables such as light, temperature, motion and color can play an important role but research provides inconsistent results. Considering this, a set of 5 quasi-experimental studies, was conducted to identify additional critical variables. According to the results, a dynamic, 3Dprinted drafting model, presented with a blue background under lighting conditions between 500–750 lux had the highest impact on spatial visualization ability of engineering technology students.


An Outcome-Based Competency Model For Systems Engineering Trainees, Vanessa J. Pietrzyk Oct 2016

An Outcome-Based Competency Model For Systems Engineering Trainees, Vanessa J. Pietrzyk

Engineering Management & Systems Engineering Theses & Dissertations

Dominant theories relating to outcome-based learning and workforce competency were synthesized into a singular outcome-based competency model to evaluate systems engineering training. A baseline model was developed using leading theories from the academic literature pertaining to competencies for systems engineers across three categories: cognitive, skill-based, and behavioral. The model was further refined via qualitative and quantitative analysis of formal interviews of subject matter experts in the field of systems engineering workforce management. The refined model classifies 28 critical competencies for systems engineers into three tiers of workforce functionality: foundational, specialized, and leadership. The resultant theoretical model is both grounded in ...

A Comparison Of Instructional Delivery Methods Based On Student Evaluation Data, John Hackworth, Carol Considine, Vernon Lewis Jan 2009

A Comparison Of Instructional Delivery Methods Based On Student Evaluation Data, John Hackworth, Carol Considine, Vernon Lewis

Engineering Technology Faculty Publications

Distance Education is an increasingly common educational delivery method. At Old Dominion University, all junior and senior level engineering technology courses are offered via distance education at least once every two years. A majority of courses in the distance education system at this university have three simultaneous delivery methods: on-campus, televised (receiving the course at an off-campus site via satellite video/audio), and internet-based video-streamed.

This paper explores the results of student course evaluation surveys for trends, in particular those trends which can be a result of the mode of delivery. Results of these surveys for 23 courses over a ...

A Qfd Decision Model For Selecting Service, Teaching, And Research Opportunities, Paul Kauffmann, Abel Fernandez, Charles Keating

Engineering Management & Systems Engineering Faculty Publications

New faculty are confronted with a barrage of information reiterating the importance of performance in the "big three" areas: teaching, service, and research / publications. From the provost to the department head, an untenured faculty member faces strong and sometimes conflicting pressures to become involved in activities ranging from committee assignments to participation in department or university research programs. Often these opportunities come with little guidance, advice, or obvious linkage to long term success in the three pillar areas and ultimately tenure. New faculty are confronted with a complex decision problem for which there is unstructured information available to develop a ...
