A lesson from reading: Perhaps? The trajectory of reading development led to a focus on prevention efforts Preventing the establishment of reading problems is now accepted practice dependent on… Early identification assessments Effective early literacy interventions Does the same pattern hold true for mathematics?

What about math? Does math develop in the same way as reading? That is, does it make “sense” to prevent math problems? Less knowledge about long term trajectories Emerging databases may help to answer this question (ECCLES, Jordan, Fuchs) Emerging evidence suggests difficulty in math is relatively stable over time

What about math? We do know that math knowledge develops across multiple domains (e.g. number, geometry) Students may be on-track in one area and at-risk in another How these domains develop and interact continues to be researched The importance of a logical scope and sequence is paramount

Characteristics of students with mathematics difficulties Different profile types exist for students with mathematics difficulties Students with mathematics difficulties often have difficulty with quick and accurate retrieval of basic facts (Hasselbring, 88) Working memory deficits (Geary, 94) Difficulty in abstracting mathematical meaning from symbols

Early Screening Cont. Goal is to maximize the amount of information collected in the minimum amount of time Predictive validity is critical (e.g. a low score in the Fall predicts difficulty at the end of the year) Predictive validity is to a broad measure of mathematics. That is we are predicting general outcomes.
