The development of assessments as part of the funded LOCUS project is described. The assessments measure students' conceptual understanding of statistics as outlined in the GAISE PreK-12 Framework. Results are reported from a large-scale administration to 3,430 students in grades 6 through 12 in the United States. Items were designed to assess…

Analyzing examinees' responses using cognitive diagnostic models (CDMs) have the advantages of providing richer diagnostic information. To ensure the validity of the results from these models, differential item functioning (DIF) in CDMs needs to be investigated. In this dissertation, the model-based DIF detection method, Wald-CDM procedure is…

The purpose of this article is to explore crossing differential item functioning (DIF) in a test drawn from a national examination of mathematics for 11-year-old pupils in England. An empirical dataset was analyzed to explore DIF by gender in a mathematics assessment. A two-step process involving the logistic regression (LR) procedure for…

A difficult result to interpret in Computerized Adaptive Tests (CATs) occurs when an ability estimate initially drops and then ascends continuously until the test ends, suggesting that the true ability may be higher than implied by the final estimate. This study explains why this asymmetry occurs and shows that early mistakes by high-ability…

Inspired by his ability to teach algebra to low-income and mostly African American and Latino urban students--and have them outscore the state averages for high-income and Caucasian students on standardized tests--Kadhir "Raja" Rajagopal, the 2011 California Teacher of the Year, provides you with a model for teaching that unleashes the…

The paper reviews a series of models designed to reduce bias in the assessment process and describes the intent of each model and their interactive effect in the process of nonbiased educational evaluation. (Author/CL)

This report examines the state of the art in assessing bilingual and/or multicultural students and asserts that dramatic improvements in assessment practices cannot be made within the context of the existing medical model. It is noted that existing assessment processes rely upon administration of technically-suspect norm-referenced measures to…

The authors suggest that efforts to comply with the protection in evaluation procedures provisions of P.L. 94-142 (the Education for All Handicapped Children Act) have been characterized by attempts to identify a single fair test for use with specific groups of minority children, and that such efforts will not result in improved efforts to…

This publication reviews issues and processes in the quest for less-biased, least-biased, non-biased assessment. It is intended to aid the school psychologist in assisting all individuals in placement or program decisions for school-age children. The first section articulates the common sources of bias in assessment and identifies concepts…

Reviews research concerning assessment of Black children and proposes a strategy to encourage fair and appropriate psychological/educational decisions. The five phases of the model include observation, testing, data analysis, and evaluation. Culture-specific tests should be used in addition to traditional measures to provide equal opportunities…

Addresses the disproportionate representation of culturally and linguistically different children in special education classes. Proposes a three-tiered response model relating to the individual practitioner, the educational process, and a larger scaled systematic response to the issues. Effective practical suggestions are offered. (Author/JAC)

Increased demands for colleges and universities to engage in outcomes assessment for accountability purposes have accelerated the need to bridge the gap between higher education practice and the fields of measurement, assessment, and evaluation. The "Handbook on Measurement, Assessment, and Evaluation in Higher Education" provides higher…

The Nonbiased Assessment module contains seven sections that provide information on various issues relevant to the construction of programs for assessing minority group children. Each section, in addition to the discussion of the topic, contains a list of objectives for the workshop participant or reader, a pretest, simulations, and an annotated…

The report describes research on the effects of labeling children from minority groups as retarded and includes a review of a system of multiculturalistic pluralistic assessment (SOMPA), an instrument for evaluating the abilities and potentialities of children based on different aspects of performance. Listed among findings of the Riverside study,…

This handbook describes the Assessment and Intervention Model for the Bilingual Exceptional Student (AIM for the BESt), an instructional/intervention approach to the education of language minority students. The model aims to improve academic performance through use of shared literature and Graves writing workshops, reduce inappropriate referrals…
