CONFIRMATORY FACTOR ANALYSIS OF THE QUESTIONNAIRE OF ATTITUDE TOWARD STATISTICAL GRAPHS FOR USE IN SCIENCE EDUCATION

Summary/Abstract: This study describes the modification of an instrument originally developed for measuring attitudes towards statistical graphs to instead measure elementary pre-service teachers’ attitudes towards line graphs in science. As a result of context-modification and in utilizing Confirmatory Factor Analysis (CFA), the finalized instrument comprises 32-items that incorporate constructs of enjoyment, confidence, usefulness and learning preferences. The revised instrument was found to exhibit adequate ranges of internal consistency and reliability. Based on a variety of completed analyses, the revised instrument appears to have maintained original psychometric fidelity and is recommended for use as an assessment of pre-service teachers’ attitudes towards line graphs in science.
