An investigation of spelling proficiency at the grade four level (N=174) revealed (1) pronounced gender differences favoring females, (2) program differences for two grade four spelling programs, (3) standardized test differences, (4) psychometric inconsistencies between grade equivalent and standard scores, and (5) a distinct error pattern for…

Conducted two studies to clarify nature of anchoring errors in clinical judgments. Judgments from 103 undergraduates in Study 1 evidenced neither anchoring errors nor gender differences. Judgments from 157 psychologists in Study 2 affirmed adjustment and mitigation hypotheses over anchoring hypothesis alone. Mitigation process appeared adaptable…

Application of a quantitative and qualitative error classification system to the spelling errors of 21 learning-disabled (LD) and 21 non-learning-disabled (NLD) matched college students found LD subjects exhibited a significantly greater total spelling error rate and percentage. Differences were also found on qualitative spelling variables for…

The purpose of this study was to analyze the errors made by high school students in practical biology and the extent to which boys and girls differ in terms of the frequency of errors committed. The subjects included 317 students from the twelfth grade sampled from five different schools in Nigeria. A criterion level of 0.05 was set to test the…

On the Australian Mathematics Competition, boys responded correctly to more questions than did girls, but this difference came largely from a handful of questions. Responses to questions where sex differences occurred are discussed. (MNS)

Explored the relationship among conceptual tempo, age, sex, and performance of preschool children on the visual association subtest of the Illinois Test of Psycholinguistic Abilities. (Author/DB)

Twenty-five infants were tested every two weeks on the AB Object Permanence Task, from the time they first reached for a hidden object until they were 12 months old. Results indicate that the AB provides an index of the ability to carry out an intention based on stored information despite a conflicting habitual tendency. (Author/RH)

Errors in self-reports of three academic performance measures are analyzed. Empirical errors are shown to depart radically from both no-error and random-error assumptions. Self-reports by females depart farther from the no-error and random-error models for all three performance measures. (Author/BW)

To learn more about the specific nature of the teaching and learning problems involved, researchers conducted a clinical study of 20 high school students enrolled a BASIC course. Investigators presented each student with a sequence of eight programming problems, ranging from easy to difficult. They asked questions to track student thinking and…

This report evaluating the Kansas Reflection-Impulsivity Scale for Preschoolers (KRISP), developed as an easier task version of the Matching Familiar Figures Test for school-age children, presents an analysis of data on 1,408 children of widely varying backgrounds. Eighteen samples of children, ranging in age from 2 years and 5 months to 6 years…

The ranking of acceptability accorded by 316 young native English-speaking and bilingual adults to the 11 most common morphological errors of nonnative speakers of English are correlated with the age, sex, linguistic sophistication, and bilingual status of the native speakers. (PMJ)

Describes study of 9- to 11-year-olds conducted in Great Britain that was designed to analyze the means by which elementary school children familiarized themselves with a large database. Types of error and frequency of occurrence are examined, query formulation is discussed, and the importance of keyboard skills is addressed. (nine references)…

This study investigated sex differences in chemical problem solving among Nigerian secondary school chemistry students (100 males and 100 females). Male students excelled over the female students in the following problem-solving processes: (1) problem understanding; (2) construction and execution of solution plans; (3) exhibition of structural…

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)…

These proceedings include two lectures followed by working group and topic group contributions in reduced format. The two lectures were by Heinrich Bauersfeld, speaking on contributions to a fundamental theory of mathematics learning and teaching, and Henry Pollak, speaking on the relationship between applications of mathematics and the teaching…
