MAHMUD, Mirna C  e  GUTIERREZ, Oscar A. Teaching Strategy Based on Conceptual Change for the Transformation of Misconceptions in Learning Science. Form. Univ. [online]. 2010, vol.3, n.1, pp.11-20. ISSN 0718-5006.  http://dx.doi.org/10.4067/S0718-50062010000100003.

The objective of this research is to determine the effect of the didactic strategies based on conceptual changes for the transformation of misconceptions about heat and temperature in College students of careers related to science. The design consisted of applying an initial test on previous ideas related to the concepts of heat and temperature. Then, a learning experience with instructional activities based on conceptual change model was done to then apply a new test to assess to evalúate the new learning. The descriptive statistical analysis of the items before and after treatment revealed that there were slight changes on misconceptions. Moreover, the results of applying the t-Student statistic suggest that the strategy based on conceptual changes is effective for the better comprehension of the concepts of heat and temperature.

Palavras-chave : conceptual change; teaching of science; temperature; misconceptions.
