Tasks that ask students to label rational number points on a number line are common not only in curricula in the upper elementary school grades but also on state assessments. Such tasks target foundational rational number concepts: A fraction (or a decimal) is more than a shaded part of an area, a part of a pizza, or a representation using…

In this paper the author attempts to describe the actual linguistic problems of the retardates, compare their language with that of normal children and thereby tries to illustrate that although the language of retardates delay, they acquire language in the same sequence, as compared with the normal children. Three moderately retarded children with…

This paper empirically investigates elder care nurses' negative knowledge. This form of experiential knowledge is defined as the outcome of error-related learning processes, focused on how something is not, on what not to do in certain situations or on deficits in one's knowledge or skills. Besides this definition, we presume the existence of…

In order to explore the impact of a degraded semantic system on the structure of language production, we analysed transcripts from autobiographical memory interviews to identify naturally-occurring speech errors by eight patients with semantic dementia (SD) and eight age-matched normal speakers. Relative to controls, patients were significantly…

This article analyzes the braille spelling errors of 16 Greek students who are blind. More specifically, it explores the types of spelling errors, the students' attitudes toward spelling, and the relationship between spelling and reading strategies.

The treatment of errors in mathematics classrooms has gained attention in recent years, with many researchers suggesting that errors should be used as starting points for student inquiry into mathematics. In the study reported in this article, we examined how teachers used discourse around errors to generate inquiry by looking at the treatment of…

An analytical technique is reviewed that allows a researcher to decompose informant reports into their respective trait, informant bias, and measure specificity using LISREL. The technique is illustrated in a study of decision making in 151 police agencies. (SLD)

This article explores the attribution of linguistic resources to multilingual students in a primary school in the Netherlands.

Its focus is on the…

Using Kazemi's and Stipek's (2001) framework of classroom practice, the discourse between students enrolled in a mathematics-for-teachers course and their instructor is examined. The teacher's practice is in transition from a focus on having students share multiple strategies toward a practice that additionally includes the mathematical…
