Taking into account the requirements for the teaching of chemistry, several visualization resources (software, videos, animations, molecular models, among others) are available. These visual aids are used in order to enhance the understanding of chemical phenomena in the classroom. However, many teachers make scant use of these resources, limiting macroscopic understanding of chemical science. Thus, this article discusses chemistry teachers' views on several aspects such as using visual aids in teaching chemistry, a resource most widely used in classes on atomic models, isomerism and spatial geometry.
