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

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.
