However, several researchers argue that little is known about the cognitive value of graphical representations, be they schematic visualizations, such as diagrams or more realistic, such as virtual reality. The study reported in the paper…

It is generally accepted that the ability to visualize is an important tool for engineers and technologists especially in engineering graphics. Enhancing the spatial visualization abilities of engineering students has long been a focus of engineering graphics educators. Over the years a variety of test and procedures have been developed to…
