A number of studies indicate that the use of holographic displays can influence spatial visualization ability; however, research provides inconsistent results. Considering this, a quasi-experimental study was conducted to identify the existence of statistically significant effects on sectional view drawing ability due to the impacts of holographic displays. In particular, the study compared the use of three different types of displays: 3D printed model, computer generated model, and holographic model to determine whether a significant difference exists towards sectional view drawing ability, among engineering technology students. According to the results of this study, it is suggested that the impact of …


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 Jan 2018

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.

The benefit of using static versus dynamic visualizations is a controversial one. Few studies have explored the effectiveness of static visualizations to those of dynamic visualizations, and the current state of the literature remains somewhat unclear. During the last decade there has been a lengthy debate about the opportunities for using animation in learning and instruction. More specifically it has been shown that dynamic visualizations often provide no advantages over static visualizations. If they had shown advantages, it was due to the fact that more information was available in the animated than in the static version. Given this result, the …


Using Computer-Aided Design Software And 3d Printers To Improve Spatial Visualization, Petros Katsioloudis, Millie Jones Jan 2015

Many articles have been published on the use of 3D printing technology. From prefabricated homes and outdoor structures to human organs, 3D printing technology has found a niche in many fields, but especially education. The education of technology and engineering students has come a long way from traditional instruction using hand drawings. Although drawings may still be a part of a students learning, computer technology has been embraced in this field for several years. With the introduction of AutoCAD technical drawing programs and now 3D printing, learners can use 3D printed models to develop their spatial abilities in technology and …
