Representations
Chemists have developed advanced written notations to convey the structure of molecules.
Although the symbolism represents only the connectivity of the atoms, these impoverished
representations imply the specific geometry of the molecule.
Representations trains students to relate the notation of the impoverished drawing with
the richness of the three dimensional structure of the molecule. Random presentation of
a variety of impoverished drawings, typical of textbooks, are compared with
three-dimensional models of rotating molecules drawn using advanced lighting and
rendering techniques. The models may be correct or may include logical but incorrect
interpretations of the drawing. Students identify the accuracy of the model and receive
corrective feedback if appropriate.
Setup program
Representations requires a computer running the Microsoft Windows 8,
Windows 10, Windows 11, or later Windows operating system.
