Abstract

SILVA JUNIOR, José Nunes da; BARBOSA, Francisco Geraldo  and  LEITE JUNIOR, Antonio José Melo. Virtual polarimeter: development, use and evaluation of an educational software application. Quím. Nova [online]. 2012, vol.35, n.9, pp.1884-1886. ISSN 0100-4042.  https://doi.org/10.1590/S0100-40422012000900032.

Optical activity is the ability of chiral substances to rotate the plane of plane-polarized light and is measured using an instrument called a polarimeter. An educational software application to explore, both interactively and visually, the concepts related to polarimetry to facilitate their understanding was developed. The software was field-tested and a questionnaire evaluating the graphics interface, usability and the software as an educational tool, was answered by students. The results characterized the computer application developed as an auxiliary tool for assisting teachers in lectures and students in the learning process.

Keywords : polarimetry; optical activity; educational software.
