The Developmental Characteristics of Young Children Prenatally Substance-exposed (open access)

The Developmental Characteristics of Young Children Prenatally Substance-exposed

The purpose of this study was to explore the developmental characteristics of young children (ages 11-60 months) with prenatal substance-exposure. A developmental rating scale, the Developmental Checklist (DC) of the Developmental Observation Checklists (DOCs) was utilized. The DC measures the domains of language, motor, social/behavioral, and cognition, as well as overall developmental status.

An Examination of Regular Education Elementary Teachers' Attitudes Toward Students with Emotional/Behavioral Disorders (open access)

An Examination of Regular Education Elementary Teachers' Attitudes Toward Students with Emotional/Behavioral Disorders

This study examined the attitudes of regular education teachers at the elementary school level, toward mainstreaming students with emotional/behavioral disorders (E/BD) and identified variables which were correlated with those attitudes.

Preservice Teacher Attitudes towards Nonvocal Individuals using High Technology Augmentative Communication Devices versus Low Technology Communication Boards (open access)

Preservice Teacher Attitudes towards Nonvocal Individuals using High Technology Augmentative Communication Devices versus Low Technology Communication Boards

The attitudes of preservice teachers towards individuals who are nonvocal and using either a high technology augmentative communication (HAC) device or a low technology communication board were investigated. A rating scale was devised, consisting of three sub-scales. The three sub-scales measured preservice teachers' estimates of intelligence, academic potential, and social acceptance in the regular education setting. Reliability and validity were established through a pilot study. Preservice teachers viewed videotapes of children using either high technology or low technology augmentative communication devices and subsequently completed the rating scale based on the videotapes. Results indicated that preservice teachers perceived the same child as having greater academic and social acceptance potential when using high technology augmentative communication.

Influence of Item Response Theory and Type of Judge on a Standard Set Using the Iterative Angoff Standard Setting Method (open access)

Influence of Item Response Theory and Type of Judge on a Standard Set Using the Iterative Angoff Standard Setting Method

The purpose of this investigation was to determine the influence of item response theory and different types of judges on a standard. The iterative Angoff standard setting method was employed by all judges to determine a cut-off score for a public school district-wide criterion-reformed test. The analysis of variance of the effect of judge type and standard setting method on the central tendency of the standard revealed the existence of an ordinal interaction between judge type and method. Without any knowledge of p-values, one judge group set an unrealistic standard. A significant disordinal interaction was found concerning the effect of judge type and standard setting method on the variance of the standard. A positive covariance was detected between judges' minimum pass level estimates and empirical item information. With both p-values and b-values, judge groups had mean minimum pass levels that were positively correlated (ranging from .77 to .86), regardless of the type of information given to the judges. No differences in correlations were detected between different judge types or different methods. The generalizability coefficients and phi indices for 12 judges included in any method or judge type were acceptable (ranging from .77 to .99). The generalizability coefficient and phi index …

Outliers and Regression Models (open access)

Outliers and Regression Models

The mitigation of outliers serves to increase the strength of a relationship between variables. This study defined outliers in three different ways and used five regression procedures to describe the effects of outliers on 50 data sets. This study also examined the relationship among the shape of the distribution, skewness, and outliers.
