Abstract:
The purpose of this research was to study the effects of the decision making activities for elementary school students. The samples consisted of 60 Grade 6th students. The samples were randomly selected and assigned by matched scores into the experimental group and control group, 30 persons a group. The research instruments were; 1) the decision making activities for elementary school students created by the researcher, and 2) the Iowa Gambling Task™, Version 2 (IGT™2). The experimental group received 8 times of the activities, 50 minute a time. The control group received an ordinary teaching activity. The assessment tool was IGT™2 for assessing 3 phases: pretest, posttest, and 3-week-follow-up. The statistics used for analyzing data were the variance analysis with the repeated measure, one between-subject variable and one within-subject variable, and the pair test with Bonferroni.
The result of this study were as follows: 1) There was the interaction between the research method and experimental time at the statistically significant level of .05, 2) the students received the decision making activities had higher decision-making scores in posttest than that in pretest at the statistically significant level of .05; and, 3) the students who received the decision making activities had higher decision making scores in follow-up than those in pretest at the statistically significant level of .05. In conclusion, the organization of decision-making activities in elementary school students was effective to increase decision-making skills in the elementary school students.
