Abstract

<p>This research aimed to examine the effect of the visual representation of an external resource on the formation of a scientific concept. Observations were carried out during a lesson on the law of inertia. As an external resource, we prepared polystyrene foam balls. The students provided with the external resource formed the scientific concept more effectively than the students without it. Through an utterance protocol and interview investigation, we were able to confirm the following: The students provided with the external resource were conscious of the polystyrene foam ball during observation. In addition, these students paid attention to the speed of the water during observation. This suggests that the visual representation of external resources has the effect of directing the student's attention towards certain aspects, which aids in the efficient formation of the scientific concept.</p>
