This commentary on the article titled "Examining the Internal Structure Evidence for the Performance Assessment for California Teachers: A Validation Study of the Elementary Literacy Teaching Event for Tier 1 Teacher Licensure" provides an overview of Performance Assessment for California Teachers (PACT), its relationship to edTPA and…

D'Eon et al. concluded that change in performance self-assessment means from before to after a workshop can detect workshop success in their and other situations. In this commentary, their recommendation is refuted by showing that (a) self-assessments with balanced over- and underestimations are still biased and should not be used to evaluate…

Lissitz and Samuelsen (2007) have proposed a framework that seemingly deems construct validity evidence irrelevant to supporting educational test meaning. The author of this article agrees with Lissitz and Samuelsen that internal evidence establishes test meaning, but she argues that construct validity need not be removed from the validity sphere.…

In response to Lissitz and Samuelsen (2007), the author reconstructs the historical arguments for the more comprehensive unitary concept of validity and the principles of scientific inquiry underlying it. Her response is organized in terms of four questions: (a) How did validity in educational measurement come to be conceptualized as unitary, and…

Discusses design and evaluation concepts and methodologies in the context of comprehensive system design (CSD) and considers the concept of error throughout. Topics addressed include six core concepts of CSD; design processes; evaluation concepts; evaluation processes, including criterion-related validity, construct validity, and systemic…

Gardner [Gardner, H. (2006-this issue). On failing to grasp the core of MI theory: A response to Visser et al. "Intelligence"] criticized some aspects of our empirical examination [Visser, B. A., Ashton, M. C., & Vernon, P. A. (2006-this issue). Beyond "g": Putting multiple intelligences theory to the test. "Intelligence"] of his "Theory of…

Changes in views of personnel selection research include changing opinions about choosing predictors and criteria, methods of data collection, and methods of evaluating selection procedures. Distinctions are made between job-relatedness, inferred from validity coefficients based on job-related criteria, and the valid measurement of a trait,…

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…

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…

This document contains eight papers from an action research program to foster good practice in adult literacy provision and policy. "Introduction" (J. Joy Cumming, Christina E. van Kraayenoord) presents an overview of the action research project and individual reports. "Assessment: Making a Difference in Adult Literacy and Numeracy…
