Distintos niveles de análisis para el estudio del cambio conceptual en el dominio de la mecánica

Abstract

A quasi-experimental study on the conceptual change in mechanics, it has been accomplished following various levels of analysis. Eighty-five students of tenth grade of a public school completed two questionnaires on mechanics phenomena, before and after being taught. The obtained results showed the presence of qualitative and quantitative changes in the cognitive structure. These changes affected the specific ideas expressed through particular answers, as well as the most general frameworks on which those answers were based. From those results some implications for didactic interest and for the investigation are commented.
