UGLIAROLO, Esteban Ariel  and  MUSCIA, Gisela Celeste. Use of multimedia technology for stereochemistry teaching at university level. Educ. quím [online]. 2012, vol.23, n.1, pp.6-10. ISSN 0187-893X.

In teaching chemistry, the biggest drawback is that atoms and molecules are very small structures to which we have no possibility to observe. Therefore, we use a mental model that is valid for the teaching of this science. The aim of this work is the implementation of ChemBio3DUltra v11.0 to generate three-dimensional representations and to help improving the quality of the teaching process in relation to traditional teaching. A sample of 200 students enrolled in the Organic Chemistry II course, and the curriculum of Pharmacy and Biochemistry careers, University of Buenos Aires, have participated in the investigation. The study group was composed of 100 students and the control group of another 100. Students were questioned on the usefulness of the topic in the development of stereochemistry.We analyzed their performance in evaluative instance. In our case we observed that the use of ChemBioUltra v11.0 has been useful for students. In the evaluative instance, approximately 50% more students got the highest score compared to the control sample.
