Using the 2006 PISA Questionaire to Evaluate the Measure of Educational Resources: A Rasch Measurement Approach
Journal Title: International Journal of Assessment Tools in Education - Year 2017, Vol 4, Issue 2
Abstract
School educational resources are key when studying school improvement due to their influence on learning outcomes. Because of this, careful attention should be given to the way educational resources are operationalized and measured. Using the 2006 PISA American sample containing 166 schools, this study aims to validate the 13-item PISA School Educational Resource Scale with Rasch analysis. Winsteps software was used in the analysis and results were used to evaluate how well the instrument measured the construct of school educational resource. Findings revealed that the PISA 2006 data gave an overall indication of good fit to the model, despite the instrument not separating respondents well. In regards to the quality of the scale, the majority of items perform consistently with the model. However, for schools above the average educational resource threshold, it appears there is a need for more items to discriminate the situation.
