The authors have developed a computer-based learning module on the unit cell of various types of crystal. The module has two components: the virtual unit cell (VUC) part and the subsequent unit cell hunter part. The VUC is a virtual reality simulation for students to actively arrive at the unit cell from exploring, from a broad view, the crystal…

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…
