Electronic Theses and Dissertations
Measuring the effectiveness of the Response to Intervention (RtI) framework has become a more urgent need in the broader context of educational policy and the high stakes associated with school improvement. In order to meet these needs, the systematic development of a series of RtI rubrics was initiated within the state of Colorado to support districts, schools, and educators with the implementation of the RtI framework. Although the staff of the Colorado Department of Education (CDE) invested significant time and resources into developing the RtI implementation rubrics, they did not conduct an evaluation of the internal validity of the tools. …

Validation Of The Item-Attribute Matrix In Timss-Mathematics Using Multiple Regression And The Lsdm, Lin Ma
Electronic Theses and Dissertations
For many cognitive diagnostic models, the item-attribute matrix (or Q-matrix) is an essential component which displays the relationship between items and their latent attributes or skills in knowledge and cognitive processes. However, it is a challenge to develop an effective Q-matrix.The purposes of this study were (1) to validate of the item-attribute matrix using two levels of attributes (Level 1 attributes and Level 2 sub-attributes), and (2) through retrofitting the diagnostic models to the mathematics test of the Trends in International Mathematics and Science Study (TIMSS), to evaluate the construct validity of TIMSS mathematics assessment by comparing the results of …
