Research Findings: The aim of this study was to investigate U.S. preschool teachers' math teaching knowledge in a specific content domain: counting and numbers. One hundred in-service and pre-service teachers participated in the study; they completed a questionnaire that is composed of learning scenarios and scenario-based math teaching questions.…

Many gifted characteristics overlap the symptoms of attention deficity-hyperactivity disorder (ADHD). The potential for the misdiagnosis of giftedness as ADHD exists, but so does the potential for a dual diagnosis of giftedness and ADHD. A decade after the misdiagnosis of giftedness as ADHD was first investigated we examine lessons learned…

Recent studies have shown that children with mathematics difficulties (MD) have weaknesses in multiple areas of mathematics. Andersson, for example, recently found that children with MD perform significantly worse than other children on clock reading tasks. The present study builds on this recent finding and aims at a more profound understanding…

A probablistic approach to classification and diagnosis of erroneous rules of operations that result from misconceptions ("bugs") in a procedural domain of arithmetic is introcuced. Variability of response errors is explicitly treated through item response theory. As a concrete example, a signed-number subtraction dataset is analyzed.…

Analyzed for examiner errors 55 Wide Range Achievement Test-Revised (WRAT-R) protocols completed by 9 practitioners for metropolitan school district. All practitioners made errors, which occurred on 95 percent of protocols and averaged 3.0 errors per protocol. Most frequent errors included failures to obtain correct ceiling or basal, and failures…

A probabilistic approach is introduced to classify and diagnose erroneous rules of operation resulting from a variety of misconceptions ("bugs") in a procedural domain of arithmetic. The model is contrasted with the deterministic approach which has commonly been used in the field of artificial intelligence, and the advantage of treating the…

Examined computational errors made by educable mentally retarded students on the arithmetic subtest of the Wide Range Achievement Test. Retarded students had a lower percent of grouping and inappropriate inversion errors and a higher percent of incorrect operation errors than regular students had in Engelhardt's study. (Author)

Evaluated the technical aspects of three Wechsler Intelligence Scale for Children-Revised (WISC-R) administrations of five psychology graduate students using the WISC-R Administration Observational Checklist (WAOC) to evaluate interrater agreement. Students performed significantly better on the second than on the first observation, with…

Examples of four interviews are presented to serve as sample evidence in support of more comprehensive diagnostic procedures in assessing reliably and validly the weaknessess and strengths of learners. The search for computational errors is seen to go beyond standard paper and pencil tests. (Author/MP)

This paper, presented at the 1979 meeting of the American Educational Research Association (AERA), investigates student errors in high school mathematics. A conceptual framework of hypothetical information-handling processes such as procedures, frames, retrieval from memory, visually-moderated sequences (VMS sequences), the integrated sequence,…

Error patterns identified in cloze tests for independent, instructional, and frustration reading levels could be useful in diagnostic work and placing of students in appropriate reading levels. (Editor)

Evaluates the efficacy of two training procedures for eliminating selective stimulus control observed with three trainable mentally retarded children. In another experiment, improvements in stimulus control were not a function of varying degrees of difficulty between stimulus sets or of a prior history of discrimination training with the less…

Implementation of an adaptive achievement test for teaching signed-numbers operations to junior high students is described. A computer program capable of finding 240 basic errors in signed-number computations was written on the PLATO system and used for analyzing a 64-item conventional test, as well as an adaptive test of addition problems. The…

A test score can be used for individual instructional diagnosis after determining whether: (1) difficulty of the test items was consistent with the complexity of the content measured; (2) items measuring the same underlying process were about equally difficult; and (3) partial credit scoring would increase the reliability of the diagnosis.

A study compared the abilities of gymnastics teachers, physical education teachers, and education majors to analyze filmed gymnastic performances and detect errors. While gymnastics teachers identified the most errors, physical education teachers did little better than the education majors did. (Authors/PP)
