This article discusses how comparability relates to current mainstream conceptions of validity, in the context of educational assessment. Relevant literature was used to consider the relationship between these concepts. The article concludes that, depending on the exact claims being made about the appropriate interpretations and uses of the…

Keith Marcus congratulates Almond et al. on an interesting article bringing together two topics that are important to the field of testing. He states that some aspects of the exposition came across as not yet fully developed, as if the manuscript had been hurried to press. In this commentary, he attempts to expand aspects of the article, which he…

A valid, reliable and practical instrument is needed to evaluate the implementation of the school-based assessment (SBA) system. The aim of this study is to develop and assess the validity and reliability of an instrument to measure the perception of teachers towards the SBA implementation in schools. The instrument is developed based on a…

As illuminated forcefully by Professor Newton's provocative analytical and historical excursion, as long as tests are employed to practical ends (prediction, selection, etc.) there is little cause for the metatheoretic angst that occasions rounds of papers on the topic of validity. But then, also, there seems little need, within this context of…

The main problem of the educational evaluation validity is that it just copies the conceptual framework system of validity from educational measurement to its own conceptual system. The validity conceptual system that fits the need of theory and practice of educational evaluation has not been established yet. According to the inherent attributive…

The growing importance of genomics and bioinformatics methods and paradigms in biology has been accompanied by an explosion of new curricula and pedagogies. An important question to ask about these educational innovations is whether they are having a meaningful impact on students' knowledge, attitudes, or skills. Although assessments are…

In an address to the National Council on Measurement in Education, R. M. Jaeger (1987) commented that there appears to be a fundamental difference in measurement philosophy between those on the two sides of the debate over the Rasch model. Jaeger's observations are explicated by contrasting the views on measurement of B. D. Wright and E. F.…

Schilling et al. (this issue) have done a commendable job in illustrating a comprehensive process of validating assessments of teacher knowledge (and, more broadly, other types of tests as well). On one hand, the concrete illustration of a process that often remains murky and incomplete is profoundly heartening, as it provides a rigorous model for…

The statewide teaching performance assessment instruments being used in Georgia, North Carolina, and Florida were examined. Forty-one reliability and validity studies regarding the instruments in use in each state were collected from state departments and universities. Georgia uses the Georgia Teacher Performance Assessment Instrument. North…

The construct validity of three spatial ability tests was assessed by determining the correlation between the test results and student class grades in various subjects for 58 eighth graders enrolled at the Burris Laboratory School, Ball State University (Muncie, Indiana). Results do not strongly support any of the tests evaluated. (SLD)

The internal structure and correlates of the South Carolina State Department of Education's Needs Assessment Instruments (NAIs) for teachers, parents, and students were examined for 61, 61, and 36 schools, respectively. The NAIs are questionnaires that assess six indicators of school effectiveness: (1) instructional leadership of the principal;…

Presents data that establish the convergent and discriminant construct validity of a new behavior-rating scale for use with the early childhood-preschool population, the Preschool and Kindergarten Behavior Scales (PKBS). The scale appears to show promise as a research tool, screening device, and assessment instrument for assessing social-emotional…

An instrument was developed to assess principal leadership. Two studies were then conducted to assess the reliability, validity, and utility of the instrument. Leadership style is the relative intensity of the presence of four modes of authority (traditional, charismatic, legal, and expert authority) and four modes of power (moral, psychological,…

Teacher knowledge has been of theoretical and empirical interest for over two decades, and development of measures is overdue. The researchers represented in this volume have been breaking new ground by developing a measure of mathematical knowledge for teaching (MKT) without guiding precedents, and in the face of differing perspectives on teacher…

Operating from multiple literature bases in cognitive psychology, mathematics education, and theoretical and applied psychometrics, Schilling, Hill and their colleagues provide a systemic approach to studying the validity of scores of mathematical knowledge for teaching. This system encompasses an array of task formats and methodologies. The…
