Rate To Measure Mathematics Teaching: Using The Many-Facet Rasch Modeling To Reevaluate The Mathematics Classroom Observation Protocol For Practices (Mcop2), Chunling Niu
Theses and Dissertations--Education Sciences
Rater-mediated classroom observation protocols are increasingly being used for teaching performance assessments, which makes identifying and controlling for various rater effects a central issue to ensure the rating quality. A series of validation studies under the classical test theory framework, including content validity, interrater reliability, and structure analysis, have been completed for the 16-item Mathematics Classroom Observation Protocol for Practices (MCOP2).
However, the MCOP2 data have never been investigated under the Rasch framework. Due to the methodological limitations of the CTT approach for rater-mediated assessments, it is imperative to examine the MCOP2 validity and reliability using …
