The application range of Cohen's Kappa is extended to the field of sequential observation data, where omission mistakes of an observer may often occur. It is shown how the omission mistakes can be incorporated into the calculation of the Kappa coefficient without violating the statistic it is based on. The enhanced coefficient is termed Kappa…

In this article, the author demonstrated how recent histories relied primarily on previous accounts and one textbook to characterize George Pierce Baker's work. This narrow assessment of "The Principles of Argumentation" limits one's understanding of his contribution to argumentation theory and pedagogy. Similarly, one has seen the need for care…

Previous studies have shown that after being trained on A-B and A-C match-to-sample tasks, adults match not only same-class B and C stimuli (equivalence) but also BC compounds with same-class elements and with different-class elements (BC-BC). The assumption was that the BC-BC performances are based on matching equivalence and nonequivalence…

Elementary school children in the United States are not developing acceptable levels of mathematical proficiency (National Center for Education Statistics, 1999), and a major concern of teacher educators is that teachers lack the depth and flexibility of mathematical understanding and the corresponding beliefs they need to teach for proficiency…

The purpose of this research was to examine the effects of implementation of argumentation in a physics classroom on students' reasoning. This research is both quantitative and qualitative in nature. Experimental design was used for the study. For the quantitative aspect of the research, students' prior knowledge in the beginning of the…

Despite the increasing use of the microgenetic methodology to examine change, the techniques employed to analyse microgenetic data remain fairly unsophisticated. This paper reviews the existing ways of analysing such data and describes their limitations. We use two recent studies to illustrate how modelling can avoid these problems and reveal…

For seven years, the author has been the parent of a wonderfully uniquely gifted little boy, who has taught her all about "exceptional" parenting. Her child, Adrian, is a "twice-exceptional" child who is both intellectually gifted and has special needs that negatively impact his development and learning. Initially, the contradictions of parenting…

This study assessed overall critical thinking ability in graduate and undergraduate students in special education at a southwestern university. A comparison of the two groups resulted in significant differences on the Watson-Glaser Critical Thinking Appraisal Form Short (WGCTA-FS) subscales for Inference, Recognition of Assumption, Deduction, and…

This paper describes a freshman composition course which looks at racism and sexism in science, and within which the instructor uses a 1989 "Atlantic Monthly" piece by R.J. Herrnstein, co-author with Charles Murray of "The Bell Curve." In his article, Herrnstein argues that the intelligence of the nation is declining because…

This guide offers more than 100 games from around the world designed to help students explore the fun of learning while developing their higher-order thinking skills. The guide is a compilation of new and traditional games, most of which can be completed with paper and pencil. Each game is classroom tested and tailored to enhance the intelligences…

In this paper it is argued that the characterization of mathematical justifications as inductive or deductive is incomplete. Promoting in classrooms the development of and discourse about a third type of reasoning, transformational reasoning, which considers the results of operations on a set of objects, may contribute to mathematics learning in…

The author states two "Birdcage Axioms" (often called the Pigeonhole principles) and shows how students can prove a variety of theorems from them. (SD)

Investigated the intercorrelations among tasks that appear to require Piagetian formal reasoning to determine whether formal reasoning is used selectively or all-pervasively. Subjects were 60 undergraduate females. (SDH)
