Assessing Differential Item Functioning And Differential Test Functioning In An Academic Motivation Scale Using Item Response Theory Methods, Gerald J. Bean
Assessing Differential Item Functioning And Differential Test Functioning In An Academic Motivation Scale Using Item Response Theory Methods, Gerald J. Bean
International Journal of School Social Work
Social work researchers and practitioners who use measurement instruments to make data-informed decisions need to ensure those decisions are based on items and scales that are free from possible bias or undesirable differential functioning. In this study, we provide an example of how a set of Item Response Theory (IRT) statistical methods and tools can be used by social work measurement researchers to assess differential item (DIF) and scale (DTF) functioning. For the example, we explored the possible race, gender, and family composition differential functioning of a scale—the Academic Motivation Scale (AMS)—developed for use by school social workers. The data …
Investigation Into The Measurement Of Student Ability: Refinements, Improvements And Enhanced Understanding Of Factors That Influence Performance, David Schreurs
Theses and Dissertations
The following series of experiments were all designed and implemented with the goal of understanding and improving undergraduate students understanding of chemistry. In order to accurately access changes in student’s chemistry understanding, the first chapter focuses on how a student’s chemistry proficiency can be most effectively measured. This includes practical recommendations for the average instructor as well as advanced methods more appropriate for researchers who require highly precise scores. With a better understanding on how to measure student proficiency, the next step was working to improve student understanding through various types of feedback following assessments. On top of establishing a …
