BANAS, Carlos; RUIZ, Constantino  y  MELLADO, Vicente. An action-research program with science teachers in a secondary school about teaching-learning on energy. Educ. quím [online]. 2011, vol.22, n.4, pp.332-339. ISSN 0187-893X.

We carried out an action-research program in Spain based in metacognitive reflection with three science teachers in a secondary school during 2002/03 and 2003/04. During the study, the participating teachers analyzed their students' alternative ideas on energy, and the teaching methods they used as were observed in the videos of their classes. They also planned new teaching units. In the article we show how their teaching models and their students' ideas on energy evolved during this program. The program has contributed to teachers' professional development, impacting significantly on the elements that form part of their teaching, and affecting positively the learning and conceptual change of their students.

Palabras llave : Secondary teachers' professional development; teaching-learning of energy; students' alternative ideas.
