FERREIRA, José  y  RODRIGUEZ, Romel. Effectiveness of the experimental demonstration activities as a strategy for the understanding the concept of Newton’s third law in students of the physical basis of the IPC. Revista de Investigación [online]. 2011, vol.35, n.73, pp.61-84. ISSN 1010-2914.

The investigation was to determine the effectiveness of the Experimental Demonstration Activities (EDA) as a teaching strategy for conceptual understanding of Newton’s third law. The theoretical reference points are conceptual understanding, the EDA and the third law of Newton. The research was a field study of descriptive and interpretive in the form of Feasible Project, a quasi-experimental design type telling prepueba-posttest with a control group and an experimental group. It was found that physics teachers based IPC classes in problem solving and in lectures, also became evident in improved understanding of Newton’s third law by students in the experimental group, compared with the control group when applying the AED. In conclusion, the AED positively influence the conceptual understanding of Newton’s third law.

Palabras clave : Experimental demonstration activities; conceptual understanding; Newton’s third law.
