The Effects of Extraneous Material and Negative Exemplars on a Social Science Concept-Learning Task for Pre-School Children.
Martorella, Peter H.; Wood, Roger
This study analyzes the relative effects of two categories of variables upon the learning of a basic social science concept by a kindergarten population. Major hypotheses were: (1) Subjects receiving treatments with low degrees of irrelevant material would score significantly higher on concept-learning measures related to the task than those receiving treatments with medium and high degrees of irrelevant data, (2) Subjects receiving treatments with the greater number of negative exemplars would score significantly higher on concept-learning measures than those receiving lesser numbers, (3) Subjects receiving treatments with the greater number of negative exemplars would have an interaction effect upon learning measures. Subjects were 789,225 kindergarten children representing a cross section of Seattle's population, according to SES data. Teaching materials were cassette recordings manually synchronized with 2x2 colored slides of concept exemplars and nonexemplars shown on a slide projector. The concept "island" was taught to children in groups of two and three, and three critical attributes were delineated. Analysis of variance indicated no significant differences. The study seems to suggest that for preschool children increasing irrelevant dimensions and reducing contrast in a social science concept-learning task are not significant factors. (WY)
