Abstract
En este trabajo se describe cómo construyen modelos y explicaciones relacionadas con la flotabilidad de los objetos macizos 4 niños de 6 años durante una propuesta didáctica sobre la flotación.
Para la recogida de datos, la intervenación se grabó en audio. Los resultados muestran que, al inicio de la secuencia, algunos niños no son capaces de justificar sus predicciones sobre la flotabilidad de algunos objetos, mientras que otros utilizan diferentes criterios para cada objeto, como el tamaño, la dureza o el peso. Sin embargo, al finalizar la secuencia, los niños utilizan ideas de un modelo precursor sobre la flotación basado en el material del que están hechos los objetos.
This paper describes how four six-year-old children construct precursor models and explanations related to the buoyancy of objects during a teaching sequence on this conceptual domain. For data collection the intervention was recorded on audio. The results show that, at the beginning of the teaching sequence, some children are not able to justify their predictions about the buoyancy of some objects, while other use different criteria for each object such as size, hardness, or weight. However, by the end of the teaching sequence, children exhibit a precursor model about flotation in which they incorporate the idea that buoyancy depends on the material the objects are made of.
