Much of the current rhetoric in areas of child and family research and in early childhood education emphasizes the importance of listening to children in research that has a direct impact on them. Despite this, there remain qualms in some research contexts and amongst some researchers about the reliability, validity and generalizability of…

Peer reviewedGoodwin, Laura D.; Goodwin, William L. – Journal of Early Intervention, 1991
Four approaches to estimating interrater reliability in early childhood special education research are illustrated and compared: correlation, comparison of means, percentage of agreement, and generalizability theory techniques. Generalizability theory techniques are proposed as a method for estimating the amount of variance attributable to…

Peer reviewedHopkins, Kenneth D. – American Educational Research Journal, 1984
In behavior research using cognitive and affective measures, there is often incongruity between the statistical analysis employed and the intended inference. This paper argues that incorporating items as levels of a random facet via generalizability theory allows the statistical examination of the inferential question in the desired universe of…

Generalizability theory, which subsumes classical measurement theory as a special case, provides a general model for estimating the reliability of observational rating data by estimating the variance components of the measurement design. Research data from the "Heart Smart" health intervention program were analyzed as a heuristic tool.…

Sandler, Andrew B. – 1987
Statistical significance is misused in educational and psychological research when it is applied as a method to establish the reliability of research results. Other techniques have been developed which can be correctly utilized to establish the generalizability of findings. Methods that do provide such estimates are known as invariance or…
