Molecular symmetry and orbitals are two important chemical concepts which can be difficult
for students to visualize in three dimensions; as such, instructors have traditionally adopted …

This study investigates students' cognitive resources for identifying symmetry elements using
survey data collected from 39 inorganic chemistry students from twelve undergraduate …

A symmetry activity using student-built models was developed in line with faculty-developed
pedagogical goals and a collaborative learning framework. The activity took place in a 3-h …

We previously observed students gesturing during a symmetry and group theory activity.
This prompted additional interviews, wherein we attempted to understand the semiotic …

This dissertation discusses the gestures produced by students as they learn about the
inorganic chemistry topic of symmetry and group theory. Also included is an overview of the …

Most chemical concepts are abstract, hierarchical, and constructed from basic to complex
concepts. Lewis structure, VSEPR theory, molecular geometry, and molecular symmetry …

Use of manipulatives to explore concepts qualitatively and quantitatively was investigated in
this study. Particle diagrams, enthalpy, VSEPR, and stoichiometry; four classes of students …

En este estudio, se exploró el uso del cómic como material didáctico en la enseñanza de la
simetría molecular para estudiantes del área de química de la Universidad Juárez …
