An Investigation to Develop a Probabilistic Equation of Performance in Relation to the Factors that Affect the Use of the Science Process Skill of Prediction by Elementary School Children.
Thiel, Robert Patrick
The two purposes of this study were: (1) to identify those factors that significantly affect the use of the science process skill of prediction, and (2) to construct and test a probabilistic equation, based on a competence-performance model of cognitive development that accounts for a child's performance on tasks involving the skill of prediction. Four factors were identified that might affect a student's performance on tasks involving prediction: (1) grade level, (2) type of rule used (seriation or classification), (3) stating or not stating a descriptive rule used, and (4) the number of attributes in each task. Six prediction tasks, developed by the investigator, were administered to 90 students, grades 3-5. By using a four factor ANOVA the type of rule and number of attribute factors were shown to be the factors significantly affecting student performance. An independent sample of 26 students, grades 4 and 5, was given the six tasks. Probabilities of success were determined and compared to predicted probabilities obtained from two equations, both based on a competence-performance model of cognitive development. A chi-square analysis revealed that both equations could account for the performance on the prediction tasks of the students in this study. Predicted differences in performance could not be detected.
