![]() ![]() For each, the previously published, refined unit cell may be rotated clockwise by 60° for comparison to a layer unit cell. (Students who used the viewer were more likely to get the problem correct because using the viewer removed the ambiguity of where atoms in the unit cell could be found. To determine the relationships between the symmetry of the overall pyrophyllite and talc structure and the symmetry of individual layers, the geometry and symmetry of each 2:1 layer of pyrophyllite and talc were analyzed. I gave students the option of using it to help them complete an exam question and ~25% of my students used it on the exam. I also asked, "As a result of your work in this class, what GAINS DID YOU MAKE in your UNDERSTANDING of each of the following?" Here are student responses for extended (solids) structureĪs you can see, there are not great differences between the year I used Studio Viewer (Spring 2016) and the year I used only model kits. The students responded more favorably to the solid state model kits, but 80% of students thought that both the model kits and Studio Viewer provided much or great help. “HOW MUCH did each of the following aspects of the class HELP YOUR LEARNING?” On the end of semester SALG in 2016, I asked students about the solid state model kits and Studio Viewer. These files can be opened on student devices so that students can individually work with 3D models of extended solid state structures. This activity describes how to generate DAE files (3D interchange file format). Atomic structure plotting / analysis (Well suited for WIEN2K, PWscf, FHI98md, VASP and more) (Unix platform). However, most students have smartphones and tablets. While students can work with the free demo version of CrystalMaker on a computer, most students don’t bring their computers to class. Since there is no lab directly associated with my class, all of our visualization activities are done in a standard lecture room during one or more 50-minute class periods. I believe that it’s important to guide students as they explore 3D extended structures. CrystalMaker files on a computer (I have a license for my laptop).We have a large selection of high-quality, finely-polished 2D and 3D laser photo crystals with different shapes and various edge styles to further. The results are images permanently etched inside the 2D or 3D photo crystals. static 3D models (generated by CrystalMaker) Laser photo crystal engraving fuses the art of photography with the advanced 3D laser crystal engraving technology.My experience is that the more representations students can master, the more likely they are to find one that helps them understand solid state structures. I’m interested in any tool that helps my students visualize solids. Science Skills, Practices, and ResourcesĪlthough I’m a solid state chemist, I still find it difficult to teach the visualization of solid state structures. ![]()
