8-9 year old pupils' mental representations of light: teaching perspectives

In several researches focused on representations of light that are children from 5 to 15 years found that these representations are often incompatible with the scientific model. 110 children participated in this research where we studied representations of children 8-9 years on the light. As a technique of research we chose the directive individual interview. The results of the research show that children of 8-9 years use different categories of representations for the light and they rarely recognize the light as a separate entity in the area, independent sources that produce it and the effects it causes during its spread.
