TL;DR: In this article, the authors argue that learners' conceptual frameworks (mental models or personal theories) resulting from conceptual change are most acutely affected by model-based reasoning, and they demonstrate the processes and products of building models of domain content, problems, systems, experiences, and thinking processes using different technology-based modelling tools.
Abstract: Conceptual change is a popular, contemporary conception of meaningful learning. Conceptual change describes changes in conceptual frameworks (mental models or personal theories) that learners construct to comprehend phenomena. Different theories of conceptual change describe the reorganization of conceptual frameworks that results from different forms of activity. We argue that learners' conceptual frameworks (mental models or personal theories) resulting from conceptual change are most acutely affected by model-based reasoning. Model-based reasoning is engaged and fostered by learner construction of qualitative and quantitative models of the content or phenomena they are studying using technology-based modelling tools. Model building is a powerful strategy for engaging, supporting, and assessing conceptual change in learners because these models scaffold and externalize internal, mental models by providing multiple formalisms for representing conceptual understanding and change. We demonstrate the processes and products of building models of domain content, problems, systems, experiences, and thinking processes using different technology-based modelling tools. Each tool provides alternative representational formalisms that enable learners to qualitatively and quantitatively model their conceptual frameworks.

TL;DR: The authors have carried out studies of state standards-based achievement tests that were administered to students with disabilities and found that the fairness and validity of the inferences made from scores on these tests were questionable.
Abstract: For anyone trying to understand the meaning of scores on state standards-based achievement tests, these are important questions to ask. Over the past few years, ETS has carried out studies of state standards-based achievement tests that were administered to students with disabilities. Specifically, the studies sought evidence about the fairness and validity of the inferences made from scores on these tests. These studies have considered those students with disabilities who took tests under standard conditions and those who took the tests under nonstandard conditions.

TL;DR: A general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies is presented and tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interob server agreement are developed as generalized kappa-type statistics.
Abstract: This paper presents a general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies. The procedure essentially involves the construction of functions of the observed proportions which are directed at the extent to which the observers agree among themselves and the construction of test statistics for hypotheses involving these functions. Tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interobserver agreement are developed as generalized kappa-type statistics. These procedures are illustrated with a clinical diagnosis example from the epidemiological literature.

TL;DR: In this article, a nova edicao do conhecido livro sobre metodologia de pesquisa de Creswell is presented, e uma obra excelente de referencia for cursos introdutorios de metodology-de-pisa em programas de pos-graduacao.
Abstract: Nova edicao do conhecido livro sobre metodologia de pesquisa de Creswell. Originalmente pensado no campo da Educacao, o autor ficou muito conhecido tambem em Administracao. Nesta nova edicao, ele procura sair da dicotomia metodos quantitativos x qualitativos, com uma otima discussao adicional sobre metodos mistos. Como um todo, e uma obra excelente de referencia para cursos introdutorios de metodologia de pesquisa em programas de pos-graduacao.
