A method for evaluating the validity of multicomponent measurement instruments in heterogeneous populations is discussed. The procedure can be used for point and interval estimation of criterion validity of linear composites in populations representing mixtures of an unknown number of latent classes. The approach permits also the evaluation of…

This paper argues that the dominant framework for conceptualizing validation evidence and analysis--the "five sources" framework from the 1999 "Standards"--is seriously limited. Its limitation raises a significant barrier to understanding the nature of comprehensive validation, and this presents a significant threat to…

The present study is an attempt to construct an information processing skills scale for higher secondary students. Information processing skills scale was developed and standardized based on the theoretical concept "Information skills in the school" engaging learners in constructing knowledge by State of New South Wales, Department of…

In "The Testing Charade: Pretending to Make Schools Better", the author's new book from which this article is drawn, the failures of test-based accountability are documented and some of the most egregious misuses and outright abuses of testing are described, along with some of the most serious negative effects. Neither good intentions…

This article extends the procedure outlined in the article by Raykov, Marcoulides, and Tong for testing congruence of latent constructs to the setting of binary items and clustering effects. In this widely used setting in contemporary educational and psychological research, the method can be used to examine if two or more homogeneous…

In causal matching designs, some control subjects are often left unmatched, and some covariates are often left unmodeled. This article introduces "rebar," a method using high-dimensional modeling to incorporate these commonly discarded data without sacrificing the integrity of the matching design. After constructing a match, a researcher…

Purpose: There is a need for well-defined language phenotypes suitable for adolescents in twin studies and other large-scale research projects. Rice, Hoffman, and Wexler (2009) have developed a grammatical judgment measure as a clinical marker of language impairment, which has an extended developmental range to adolescence. Method: We conducted…

This article examines the implications of argument-based validity for the continued development of dynamic assessment (DA) research and practice. We propose that the move toward validation as a process of interpretation and evidence-based argument is commensurable with DA but that fundamental ontological differences with conventional approaches to…

In this study, researchers compared the concordance of teacher-level effectiveness ratings derived via six common generalized value-added model (VAM) approaches including a (1) student growth percentile (SGP) model, (2) value-added linear regression model (VALRM), (3) value-added hierarchical linear model (VAHLM), (4) simple difference (gain)…

Evidence supporting the internal structure of an assessment can provide support for its scoring mechanisms. A total of 1,691 young children in the United States were assessed by their parents using the 16-month questionnaire of the "Ages and Stages Questionnaires," Third Edition (ASQ-3), and results were used to study the internal…

Two important pedagogical techniques for developing deeper mathematical understanding are to prove a given theorem in different ways and to unify the proofs of different theorems. Trigonometric angle sum and difference identities are introduced in Unit 2 of Specialist Mathematics in the Australian Curriculum (Australian Curriculum, Assessment and…

Purpose of this study is to adapt Behavioral Regulation in Sports Questionnaire (BRSQ) which developed by Lonsdale, Hodge and Rose (2008) in Turkish and review psychometry properties. The scale consists of 24 items and 6 subdimension including intrinsic motivation, integrated regulation, identified regulation, introjected regulation, external…

This article reports on the development of a custom-made questionnaire. The questionnaire was developed with the aim to compile guidelines for the professional development (PD) of mathematics teachers for the pedagogical use of information and communication technology (ICT) integration in teaching and learning. During the standardisation and…

From a theoretical perspective, most discussions of statistical learning (SL) have focused on the possible "statistical" properties that are the object of learning. Much less attention has been given to defining what "learning" is in the context of "statistical learning." One major difficulty is that SL research has…

Teaching determinants poses significant challenges to the instructor of a proof-based undergraduate linear algebra course. The standard definition by cofactor expansion is ugly, lacks symmetry, and is hard for students to use in proofs. We introduce a visual definition of the determinant that interprets permutations as arrangements of…
