The purpose of this report was to explicate the use of logistic regression and classification and regression tree (CART) analysis in the development of early warning systems. It was motivated by state education leaders' interest in maintaining high classification accuracy while simultaneously improving practitioner understanding of the rules by…

The purpose of this study was to examine the construct and predictive validity of a dynamic assessment (DA) of decoding learning. Students (N = 318) were assessed in the fall of first grade on an array of instruments that were given in hopes of forecasting responsiveness to reading instruction. These instruments included DA as well as…

A core assumption of response to instruction or intervention (RTI) models is the importance of measuring growth in achievement over time in response to effective instruction or intervention. Many RTI models actively monitor growth for identifying individuals who need different levels of intervention. A large-scale (N = 23,438), two-year…

On the basis of a study involving 40 first-grade students, compares Pascual-Leone's and Keating and Bobbitt's developmental theories of information processing by contrasting their predictions about a classification task. Results falsified Keating and Bobbitt's model. Predictions from Pascual-Leone's theory were almost wholly confirmed. (RH)

Tested the hypothesis that phonological mediation plays a critical role in the early development of reading and spelling in French. The findings corroborated predictions regarding performance involving pseudowords of different syllablic structures except for the failure to find differences between open and closed syllables. Results confirmed the…
