The article examines the need for training children with language disorders to judge the correctness or incorrectness of sentences which reflect error patterns. (PHR)

This article introduces 2 new sources of bias in probability judgment, discrimination failure and inhibition failure, which are conceptualized as arising from an interaction between error prone memory processes and a support theory like comparison process. Both sources of bias stem from the influence of irrelevant information on participants'…

There is variability in the estimation of an equating transformation because common-item parameters are obtained from responses of samples of examinees. The most commonly used standard error of equating quantifies this source of sampling error, which decreases as the sample size of examinees used to derive the transformation increases. In a…

Both the speed and accuracy of responding are important measures of performance. A well-known interpretive difficulty is that participants may differ in their strategy, trading speed for accuracy, with no change in underlying competence. Another difficulty arises when participants respond slowly and inaccurately (rather than quickly but…

Interactions between (multiple indicator) latent variables are rarely used because of implementation complexity and competing strategies. Based on 4 simulation studies, the traditional constrained approach performed more poorly than did 3 new approaches-unconstrained, generalized appended product indicator, and quasi-maximum-likelihood (QML). The…

The cross-proportion method allows both the instructor and the student to easily determine where an error is made during problem solving. The C-P method supports a strong cognitive foundation upon which students can develop other diagnostic methods as they advance in chemistry and scientific careers.

This paper presents preliminary results of pre- and post-treatment error analysis from an aphasic patient with anomia. The Interactive Activation (IA) model of word production (Dell, Schwartz, Martin, Saffran, & Gagnon, 1997) is utilized to make predictions about the anticipated changes on a picture naming task and to explain emerging patterns.…

A new Microsoft Excel spreadsheet design that enables a prompt calculation of rate constant, k values and associated errors and also addresses less common features such as the choice of an experimental curve's extent is presented. To complete the spreadsheet design, several highlights and squared colored boxes were included to assist the user and…

Exploratory factor analysis (EFA) is a frequently used multivariate analysis technique in statistics. Jennrich and Sampson (1966) solved a significant EFA factor loading matrix rotation problem by deriving the direct Quartimin rotation. Jennrich was also the first to develop standard errors for rotated solutions, although these have still not made…

This paper focuses on the identification of some conceptual factors underlying the initial learning of algebra. It describes a study which uncovered three predominant notions existing in a sample of ten 12- and 13-year olds prior to formal instruction in algebra, and the ways in which a particular approach to the teaching of algebra affected both…

The professional development organizations educate the local decision-makers by reducing the risks of automated scoring technologies to language and writing practices. These automated assessments lead to changes, which benefits private industry and conflicts with research on writing and language.

This article reviews the nature and function of recasts, a well-documented way of responding to young children. The paper challenges the definition of recast and argues that it is too broad a category to be useful, either for theories of language development or for practice. In particular, various forms of recast have featured in intervention…

Examines errors in 21 science journals, focusing on error types, editorial policy and practice, causes, consequences, and future action. Because of the serious implications of these errors, the scientific community is cautioned not to ignore the problem. Several recommendations are given. (DH)

Nonroutine problem-solving, too, involves elements of routine. Often, elementary routines such as solving for a variable are not carried out without error. In this paper, we use new findings from neuroscientific research to explain why even excellent students make mistakes in elementary routines. [For complete proceedings, see ED489597.]

Argues that the context of writing improvement helps explain writing error. Findings imply that undue efforts by teachers to prevent mistakes may hinder improvement. (RAE)
