This study describes the development of a special education teacher observation protocol detailing the elements of effective decoding instruction. The psychometric properties of the protocol were investigated through many-facet Rasch measurement (MFRM). Video observations of classroom decoding instruction from 20 special education teachers across…

In this report I share the results of a document-based, comparative case study aimed at increasing our understanding about the potential utility of state kindergarten entry assessments (KEAs) to provide evidence of English learner (EL) kindergartners' knowledge and skills and, in turn, inform kindergarten teachers' instruction.

This comprehensive evaluation of the Dynamic Indicators of Basic Early Literacy Skills Sixth Edition (DIBELS6) set of measures gives a practical illustration of signal detection methods, the methods used to determine the value of screening and diagnostic systems, and offers an updated set of cut scores (decision thresholds). Data were drawn from a…

In this paper, the authors report research focused directly on the validation of the Coding of Academic Teacher-Student interactions (CATS) direct observation instrument. They use classroom information gathered by the CATS instrument to better understand the potential mediating variables hypothesized to influence student achievement. Their study's…
