This study constitutes the secondary analysis of data collected as part of classroom instruction in a prior practitioner inquiry study. Consequently, IRB approval, parental consent, and participant assent for the present study were obtained after the conclusion of the original study.

This report examines the differences in impact estimates and standard errors that arise when these are derived using state achievement tests only (as pre-tests and post-tests), study-administered tests only, or some combination of state- and study-administered tests. State tests may yield different evaluation results relative to a test that is…

This brief research report gives an overview of a visually based methodology that has recently been used to shed light on situated decision-making in a high stakes educational assessment environment. Looking carefully at the feedback interactions taking place between senior and less senior examiners, the project aim was to gain insight into the…

The Gates Foundation's Measures of Effective Teaching (MET) project was a multi-year study of thousands of teachers in six school districts that concluded in January 2013. This review addresses two of the final MET research papers. One paper uses random assignment to test for bias in teachers' value-added scores. The experimental protocol was…

In four articles adapted from the Educational Testing Service (ETS) Research Report Series, Issue 2 of ETS Research Spotlight provides a small taste of the range of assessment-related research capabilities of the ETS Research and Development Division. Those articles cover assessment-related research aimed at developing models of student learning,…

In this article, we introduce a person-fit statistic called the hierarchy consistency index (HCI) to help detect misfitting item response vectors for tests developed and analyzed based on a cognitive model. The HCI ranges from -1.0 to 1.0, with values close to -1.0 indicating that students respond unexpectedly or differently from the responses…

This paper challenges Hanushek and Woessmann's (2008) contention that the quality and not the quantity of schooling determines a nation's rate of economic growth. I first show that their statistical analysis is flawed. I then show that when a nation's average test scores and average schooling attainment are included in a national income model,…

Although many researchers and policy analysts (e.g., Harris, Glazerman et al., 2011; 2010) consider value-added to be the state of the art in school and teacher productivity measurement, only a minority of Teacher Incentive Fund (TIF) Round 1 and 2 grantees used value-added as a measure of school or teacher performance. Fourteen of the 34 grantees…

This book meets a demand in the science education community for a comprehensive and introductory measurement book in science education. It describes measurement instruments reported in refereed science education research journals, and introduces the Rasch modeling approach to developing measurement instruments in common science assessment domains,…

Test-takers can be required to complete a test form, but cannot be forced to demonstrate their knowledge. Even if an authority mandates completion of a test, examinees can still opt to enter responses randomly. When a test has important consequences for individuals, examinees are unlikely to behave this way. However, random responding becomes more…

A suggested technique for analyzing distributions of test scores compares distributions of scores made by groups of pupils on standard tests with distributions made by other groups of students on the same tests. By identifying the percents of student scores which must be shifted to an adjacent cell (interval) to make the two distributions exactly…

The purpose of this study was to identify and describe the common learning styles of radiography students during clinical practice. Quantitative, descriptive research methodology identified the learning styles of radiography students. A single self-report questionnaire, developed to assess learning styles in clinical practice, was administered…

This paper considers the question of bias in group administered academic achievement tests, bias which is inherent in the instruments themselves. A body of data on the test of performance of three disadvantaged minority groups--northern, urban black; southern, rural black; and, southwestern, Mexican-Americans--as tryout samples in contrast to…
