Sketchy understandings: Drawings reveal where students may need additional support to understand scale and abstraction in common representations of DNA
Abstract Visual representations in molecular biology tend to follow a set of shared conventions for using certain shapes and symbols to convey information about the size and structure of nucleotides, genes, and chromosomes. Understanding how and why biologists use these conventions to represent DNA is a key part of visual literacy in molecular biology.
Probing visual literacy skills reveals unexpected student conceptions of chromosomes
Abstract Molecular biology can be challenging for undergraduate students because it requires visual literacy skills to interpret abstract representations of submicroscopic concepts, structures and processes. The Conceptual-Reasoning-Mode framework suggests that visual literacy relies on applying conceptual knowledge to appropriately reason with the different ways of representing concepts in molecular biology. We used this framework to specifically explore visual literacy related to chromosomes.

Probing visual literacy skills reveals student conceptions of scale and abstraction with respect to chromosomes
Abstract Molecular biology can be difficult for undergraduate students because course content is often taught using highly-abstract visual representations. Genetic concepts can be depicted with lines, letters, shapes, and symbols, and students need to engage their visual literacy skills to appropriately decipher these abstract representations.
