CIRINO, Marcelo Maia; SOUZA, Aguinaldo Robinson de; SANTIN FILHO, Ourides  and  CARNEIRO, Marcelo Carbone. A intermediação da noção de probabilidade na construção de conceitos relacionados à cinética química. Ciência educ. [online]. 2009, vol.15, n.01, pp.189-219. ISSN 1516-7313.

In this work we analyze the way the high school students appropriate the concepts and models related to Chemical Kinetics, mainly the kinetic model of collision between particles in chemical reaction (Collision Theory Model). This investigation was based on the studies of Piaget and Inhelder, of Piaget, Jun, and on Fischbein works, who have analyzed if young students exhibit some kind of probabilistic thinking. The methodology was based on pre and post-tests, questionnaires and on interviews. The analysis of these documents showed how the students deal with concepts about probability and how they correlate these concepts with the particles collision kinetic model in Chemistry.

Keywords : Probability; Chemical Kinetics; Collision Theory Model.
