Teaching crystal structures in undergraduate courses: a systematic review from a disciplinary literacy perspective

Abstract

Teaching engineering students how to effectively communicate using the language, representations, and tools specific to their discipline is important to their development as practitioners in their respective fields. This article...

Rethinking Undergraduate Computer Science Education: Using the 4Es Heuristic to Center Students in an Introductory Computer Science Course

“…There were multiple videos within each lecture folder, and a number of exercises were to be completed after watching the video(s). We followed the method of analysis outlined by Caro and colleagues to code each video and the accompanying exercises for how they supported and/or activated certain learner roles identified in the FRM [41]. Two researchers from the design team reviewed all the assignments and lectures that were assigned for the first two weeks of the course.…”

“…Two researchers from the design team reviewed all the assignments and lectures that were assigned for the first two weeks of the course. Similar to Caro and colleagues, each item was categorized according to the resource/role it supported learners in performing while completing the learning experience, and more than one category could be identified within a single activity [41]. For example, when students were asked to write down data definitions for structures to identify their functions, they were coded as codebreakers.…”

A Primer on Lattice Planes, Crystal Facets, and Nanoparticle Shape Control

“…When appropriately presented, nanomaterials as a subject area can be of interest to students from a range of backgrounds, including college students with limited experience in chemistry. , One text provides resources for leveraging materials chemistry to teach general chemistry topics . Nanomaterials chemistry courses have been developed for nonscience majors or science majors with minimal chemistry experience, and high school teachers have been trained in nanomaterials topics. ,,,− …”

“…In addition to visual aids, a large number of learning activities have been developed to teach crystal structure and crystallography . Some available experiments introduce crystal structure and X-ray diffraction concepts using 2D colloidal crystals formed by relatively large silica or polystyrene spheres. − These larger-scale crystals make instruction accessible by using optical microscopy and visible laser light to replace X-ray techniques.…”
