Multivariate Generalizability Theory in Educational Measurement: An Empirical Study

Generalizability Theory: An Analysis of Variance Approach to Measurement Problems in Educational Assessment

Of increasing interest to the educational assessment researchers is the reliability of scores obtained by various measurement procedures like tests, rating scales, surveys, and observation forms. Traditional methods of reliability based on Classical Test Theory (CTT) consider only one source of measurement errors. Generalizability Theory (GT) extends CTT by providing a flexible and practical fr...

Measurement Quality of the Chinese Early Childhood Program Rating Scale: An Investigation Using Multivariate Generalizability Theory

Adapted from the Early Childhood Environment Rating Scale–Revised, the Chinese Early Childhood Program Rating Scale (CECPRS) is a culturally comparable measure for assessing the quality of early childhood education and care programs in the Chinese cultural/social contexts. In this study, 176 kindergarten classrooms were rated with CECPRS on eight dimensions of program quality. Multivariate gene...

Generalizability Analysis for Educational Assessment

Evidence on the uncertainty attached to school and individual scores is required to avoid overinterpretation of scores. Generalizability analysis provides a standard error (SE) that is a suitable indicator of uncertainty; a value can be obtained for a design already executed or for a design being considered for possible use. Assessments depart from traditional measurements in ways that require ...
