Resumen de ConfChem Conference on Interactive Visualizations for Chemistry Teaching and Learning: Research into Practice—Visualizing the Molecular World for a Deep Understanding of Chemistry
A deep understanding of chemistry requires internal visualization of structures and processes at the molecular level to rationalize observable chemical and physical properties, and make sense of chemistry symbolism and mathematical relationships. The paper argues that accurate mental models of the molecular world are needed to address the student misconceptions described in the literature, and describes the potential and limitations of the VisChem animations to develop useful mental models. A constructivist learning design has been developed and evaluated as a best-practice strategy for effectively using the VisChem resources for learning. This communication summarizes one of the invited papers to the Interactive Visualizations for Chemistry Teaching and Learning ACS CHED Committee on Computers in Chemical Education online ConfChem held from May 8 to June 4, 2015. The lively discussions that followed addressed the difficulty of showing the crucial role of ion hydration without producing cognitive overload, the need to build a visual literacy through repeated and progressive use of molecular animations, and the complementary nature of animations and simulations to portray the molecular world.
