Abstract:
The purpose of this study was to examine an interaction of visual presentation formats and cognitive styles on the rule learning of Mathayom Suksa three students. The subjects were one hundred and eighty Mathayom Suksa three students of Maerimwitayakom school and Sunkumpang school, Chiengmai Province. The cognitive styles of the subjects were determined by the Group Embedded Figures Test and labeled as field-dependence, field-independence and the middle between field-dependence and field-independence. Sixty subjects were randomly selected for each cognitive styles group. The subjects in each group, then, were randomly divided into two sub-groups for two treatments of presentation formats : sequential-image and simultaneous-image. The material used in this study was fifteen sets of slides carrying fifteen rules. Each set composed of four pictures. The presentation time for each set of pictures was 28 seconds. The subjects were allowed to have 30 seconds to check the correct rule on the answer sheets provided. The data were analyzed by Two-Way Analysis of Variance. The pairwise differences were tested by Scheffe Method. The results of the study were as followings : 1. There was no significant interaction between visual presentation formats and cognitive styles on rule learning. 2. There was significant differences between sequential-image presentation and simulataneous-image presentation on rule learning at the .01 level of confidence. 3. There was significant differences among field-dependence, field-independence and the middle between field-dependence and field-independence on rule learning at the .01 level of confidence. 4. There was no significant differences between sequential-image presentation and simultaneous-image presentation on rule learning of the field dependent subjects. 5. The simultaneous-image presentation was found to be superior to sequential-image presentation on rule learning of the subjects whose cognitive style were in between field-dependence and field-independence at the .05 level of confidence. 6. The simultaneous-image presentation was found to be superior to sequential-image presentation on rule learning of the field-independent subjects at the .01 level of confidence. 7. By using simultaneous-image presentation, the field-independent subjects performed the rule task significantly higher than the field-dependent and the middle group subjects at the .01 level of confidence.
