Abstract
In dental education the model core curriculum include “the rubber dam dry field method” and the students have to select the right rubber dam clamp to use. We conducted an experiment using the rubber dam clamps as the visual material for the purpose of discovering how the students recognize the clamps and we came to the conclusion as follows.
1. The eye movement tracks starting to scan from the target clamp to the No. P 1 clamp were classified into three types.
2. It was supposed that the scanning directions were determined by peripheral vision. Half of the examinees started to scan the clamp from that of a similar (or same) target and the remainder started from the clamps unlike the target.
3. In the look which dissipated from the one different from the target, the number of stops, and the duration of the stops showed a tendency to be numerous.
4. Each case of error in recognizing the figure of the rubber dam clamp was observed in a “clockwise”pattern.
Upon analysis, it was suggested that attentive information search worked in the eye movements that started to scan from the clamp unlike shaped to the target first rather than those which started from that similar shaped to the target.
