ROBLE, María B; SANCHEZ, Lidia P; MARTIN, Ana M  y  SPELTINI, Cristina. Reasoning Styles in Learning the Concept of Chemical Equilibrium. Inf. tecnol. [online]. 2006, vol.17, n.6, pp.165-168. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642006000600024.

The objective of this work was the identification of the different styles of reasoning associated with learning chemical equilibrium concepts. A written questionnaire was designed, using five multiple choice closed questions. This survey, which was anonymous and voluntary, was submitted to first year students attending different programs within the Engineering School of Buenos Aires University. The data obtained was complemented with oral interviews of Chemical Engineering students of the same academic level as those submitting the questionnaire. The answers were organized based on emerging categories which were redefined as the investigation proceeded. The results from different student populations were analyzed separately. The analysis of the results suggested that the styles of reasoning identified did not differ significantly between the two populations, although the students of Chemical Engineering demonstrated better comprehension of chemical equilibria. The analysis of these results will allow professors to select and adapt teaching activities in order to allow the students to acquire a correct and lasting conceptualization of the chemical equilibrium concept.

Palabras clave : chemical equilibrium; chemistry learning; teaching; styles of reasoning.
