Abstract

RUIZ, Didier L  and  PALOMEQUE, Liliam A. A methodology to the study of preconceptions about chemistry through the analysis of graphics expressions. Rev.Colomb.Quim. [online]. 2015, vol.44, n.1, pp.36-45. ISSN 0120-2804.  https://doi.org/10.15446/rev.colomb.quim.v44n1.54044.

Graphic answers about meaning of chemistry were examined in men and women (around 17 years old) enrolled in remedial courses in sciences areas. Representations of laboratory material and chemical experiments predominated. The icons category (representations of sensations and feelings or isolated geometric figures) appears frequently in population around 17 years old. The analysis shows the percentage of population that includes the human body in their representation is never upper than 30%; when human representations were done, seems they are experimentalists; the human body is not part of the chemical study. By vocational orientation examination, predominance for men in scientific careers and women in health areas were found. The research concludes is possible enquire the essential perception about the chemistry by analyzing of graphic expressions and considering correlations between age, sex and vocational orientation. This information is useful to planning and orienting the classroom activities. In addition, it is possible to investigate paradigms and preconceptions and to stablish the abstraction level and the knowledge about scope and applicability of the chemistry.
