An Investigation of Portions of a Model Hierarchy for the Acquisition of the Concept of Speed.
Kavanagh, Daniel Cushing
Presents the use of Piaget-type tasks in interviewing 108 students (grades 6, 7, and 8), to test the validity of a proposed model through which a child must pass in order to understand a specific scientific concept. The subjects' answers were scored based on the substages of development in each of five tasks involving the concept of speed. Scalogram analysis techniques were used to test for the existence of the proposed hierarchy of difficulty among all the tasks. A Kruskal-Wallis one-way ANOVA was used to test the relationship between the subjects' IQ and ability to complete the tasks successfully. Kolmogorov-Smirnov's two-sampled two-tailed test was used to test the possibility of significant difference between scores of males and females. Grade level differences on task scores were investigated through the use of the Chi-square Test for K Independent Samples. Findings indicated that the five tasks did form a hierarchy but not in the predicted order. The results also indicated a significant difference between performance and grade level as measured by task scores. A significant difference between the IQ of the subject and his task achievement was reported. (Author/EB)
