- Abstract
The article analyzes children's predictions and explanations of unfamiliar phenomena, the formation of images through pinholes by the use of extended light sources. Results of the study indicate that a prevalent model among children for image formation involves light that carries information about the source and travels as a holistic entity. The initial predictions for either the small or large hole show half of the children attributing the shape of the image solely to the hole while the other half of the children bring in the shape of the light source. Of the children who were asked for two predictions, first with the large hole and then with the small hole, one quarter predicted a different effect for each. Closed examination indicated that the children do not think that the images are actually caused by the reflection of light. Rather, the children generalize the use of the term to refer to any entity that produces the shape of an object.
