An Empirical Study Of The Equipercentile Assumption As A No-Treatment Expectation In Title I Evaluations, Alan C. Nowakowski

Dissertations

The focus of this study was the tenability of the underlying assumption of Model A, the norm-referenced model, of the Title I Evaluation and Reporting System (TIERS). Model A estimates the no-treatment expectation from normative data. The assumption made by the Model is that, in the absence of special treatment, student groups maintain a constant percentile position in relation to national norms.

The study examined the extent to which student groups maintain a constant percentile position over a six month period. The study used a sizable representative student subsample of the standardization group for the 1978 Metropolitan Achievement Test (MAT). …

A Confusion Matrix Intelligibility Testing Procedure For Preschool Children, Jane C. Coe-Kruse

Masters Theses

This study was conducted to develop and examine a procedure for testing and analyzing the speech intelligibility of preschool children through the use of a phonetically balanced pictured word list, confusion matrices, and computer analysis. Four subjects and 15 listeners were used to obtain data on perception of sound production. The results indicate that use of this procedure differentiates varying speech intelligibilities and allows for effective analysis of sound production parameters as they pertain to speech intelligibility.
