Goodwin, Amanda P.; Petscher, Yaacov; Carlisle, Joanne F.; Mitchell, Alison M. – Journal of Research in Reading, 2017
This study examined the dimensionality of morphological knowledge. The performance of 371 seventh- and eighth-graders on seven morphological knowledge tasks was investigated using confirmatory factor analysis. Results suggested that morphological knowledge was best fit by a bifactor model with a general factor of morphological knowledge and seven…

Foorman, Barbara R.; Petscher, Yaacov; Schatschneider, Chris – Florida Center for Reading Research, 2015
The Florida Center for Reading Research (FCRR) Reading Assessment (FRA) consists of computer-adaptive reading comprehension and oral language screening tasks that provide measures to track growth over time, as well as a Probability of Literacy Success (PLS) linked to grade-level performance (i.e., the 50th percentile) on the reading comprehension…

Reed, Deborah K.; Vaughn, Sharon; Petscher, Yaacov – Learning Disability Quarterly, 2012
In this study, the authors examined the validity of a holistically scored retell within a confirmatory factor analysis framework by comparing the fit of a three-factor model of reading with the data from a diverse sample of seventh and eighth graders. The final model demonstrated adequate fit, [chi][squared](32) = 97.316; comparative fit index =…

Reed, Deborah K.; Petscher, Yaacov – Society for Research on Educational Effectiveness, 2011
The purpose of this study was to improve the utility of retell protocols by more clearly identifying the testing conditions under which students demonstrate better performance. The research questions concern whether the wording of the initial prompt, the inclusion of a follow-up prompt, or the opportunity to silently re-read the passage is related…

Petscher, Yaacov – Journal of Research in Reading, 2010
A meta-analysis of the relationship between attitudes in reading and achievement in reading was conducted to provide a statistical summary to the observed variability in the magnitude of previously reported effect sizes. A total of 32 studies, with a total sample size of 224,615 were used, and included a total of 118 effect sizes. A multi-level…
