How Spanish-speaking children spell English words was studied with 38 Spanish-speaking and 34 English-speaking second and third graders. Spanish-speaking students produced more errors that were consistent with the correct application of Spanish phonological and orthographical rules (predicted errors). Implications for bilingual education are…

A possible role of the cerebellum in detecting and recognizing event sequences has been proposed. The present study sought to determine whether patients with cerebellar lesions are impaired in the acquisition and discrimination of sequences of sensory stimuli of different modalities. A group of 26 cerebellar patients and 26 controls matched for…

Background: Williams syndrome (WS) and Down syndrome (DS) are two neurodevelopmental genetically based disorders which exhibit mental retardation with a unique cognitive profile. Naming in individuals with WS and DS has been investigated in several studies, with results indicating that the performance of children with WS and DS is at a similar…

In recent research, two qualitatively different classes of mental operations have been identified. The performance of one type of cognitive task requires attention, in the sense of mental effort, for its execution, while the second type can be performed automatically, independent of attentional control. Further research has shown that automatic…

The Concepts in Secondary Mathematics and Science (CSMS) and Strategies and Errors in Secondary Mathematics (SESM) research projects based at Chelsa College, England, have shown the marked reluctance of secondary school students to use fractions when solving mathematical problems, even though they have been taught the topic for a number of years.…

A program of research was conducted to study transitions from preoperational to concrete operational forms of spatial imagery (area 1), to compare results from spatial imagery studies based on open-ended measures (such as drawings) with results based on reaction time measures (area 2), and to study anticipatory imagery in the contexts of memory…

Recent research on solving addition and subtraction word problems has resulted in the construction of theoretical models of children's problem-solving processes. Some of these models have been translated into computer programs. Characteristics and predictions of the theoretical analysis developed by Riley, Greeno, and Heller (1983) are discussed…

Linear syllogisms present two premises, each describing a relation between two terms. The individual's task is to infer the relation among the three terms of the linear syllogism, and then answer a question about one or more of these relations. For example, "John is taller than Bob. Sam is shorter than Bob. Who is the tallest?" Students…

The literature on proportional reasoning is reviewed. After methodology is discussed, strategies used to solve proportion problems, variables that influence performance, and training studies are each considered. (MNS)

This study examined the interaction between working memory and language comprehension in children with specific language impairment (SLI), focusing on the function of the central executive component and its interaction with the phonological loop (A. D. Baddeley, 1986) in complex working memory tasks. Thirteen children with SLI and 13 age-matched…

Argues that a computer-based programming tutor for novice programmers needs to take into account not only the types and frequency of bugs found in the programs, but the intentions and knowledge state of the programmer. A first version of such a program was developed on the basis of the bug types found in a number of pencil-and-paper studies with…

This report describes PROUST, a computer-based system for online analyses and understanding of PASCAL programs written by novice programmers, which takes as input a program and a non-algorithmic description of the program requirements and finds the most likely mapping between the requirements and the code. Both the theory and processing techniques…

In a test administered to Spanish-speaking students of English as a second language at the elementary and intermediate levels, the results indicated the subjects' reliance on the strategies of overgeneralization and transfer was qualitatively different. Implications of the results are discussed. (Author/RM)

A test administered to 73 adults learning English as a second language revealed a highly consistent order of relative difficulty in the use of eight functors across different language backgrounds. This study also confirmed earlier results indicating that children and adults use common strategies and process linguistic data similarly. (Author/KM)

This study investigated the rates of successful mathematical performance and errors of information processing in third-grade children in California and continued an investigation of these factors in sixth-grade children. The objectives were to: (1) identify areas of mathematics in which the children had recognizable strengths and weaknesses, (2)…
