This study investigated the relationship between parenting stress and relational conditioning. Fourteen students who were not mothers, 14 mothers who reported high parenting stress and 14 mothers with low parenting stress completed two matching-to-sample (MTS) computer tasks, each requiring formation of three 3-member classes. The first MTS task…

Differential performance results occur when a specific population subgroup achieves a passing rate which is significantly lower than that of the normative reference group. African Americans do less well, in general, on all types of assessments, including constructed-response tests. The present study examined the writing styles of African American…

Although SAS PROC CALIS is not designed to perform multigroup comparisons, it is believed that SAS can be "tricked" into doing so for groups of equal size. At present, there are no comprehensive examples of the steps involved in performing a multigroup comparison in SAS. The purpose of this article is to illustrate these steps. We demonstrate…

This paper makes a study of error analysis and its implementation in the EFL (English as Foreign Language) classroom teaching. It starts by giving a systematic review of the concepts and theories concerning EA (Error Analysis), the various reasons causing errors are comprehensively explored. The author proposes that teachers should employ…

It is one thing to be able to count and share items proficiently, but it is another thing to know how counting and sharing establish and identify quantity. The aim of the study was to identify which measures of numerical knowledge predict children's success on simple number problems, where counting and set equivalence are at issue. Seventy-two…

This study investigated the recognition of Swedish inflected nouns in two participant groups. Both groups were Finnish-speaking late learners of Swedish, but the groups differed in regard to their Swedish language proficiency. In a visual lexical decision task, inflected Swedish nouns from three frequency ranges were contrasted with corresponding…

Research suggests that allowing individuals to control their own practice schedule has a positive effect on motor learning. In this experiment we examined the effect of task difficulty and self-regulated practice strategies on motor learning. The task was to move a mouse-operated cursor through pattern arrays that differed in two levels of…

Standardized and nonstandardized assessments of phonological awareness skills were administered to two groups of 6-year-old children. Group 1 passed a language screening but exhibited mild or moderate phonological impairments on the "Assessment of Phonological Processes--Revised." Group 2 passed a language screening and exhibited no phonological…

An attempt to systematize the description of the errors that programers make. (Author)

The Mathematics subtest of the Peabody Individual Achievement Test is analyzed and its content represented in a format similar to that used in diagnostic math tests. An error analysis matrix is provided and its use is illustrated with application to the mathematics performance of a sixth grade child. The subtest is recommended as a diagnostic test…

Specific evaluation design is a non trivial problem which must be developed through a set of procedures involving considerable study of the enterprise to be evaluated. Three criteria to be considered when an evaluator provides data for a decision maker are: (1) the percentage of the evaluation data that are actually used by the decision maker; (2)…

This article looks at the problem of obtaining accurate income data from cross-sectional surveys and explores the implications of rounding of income to the class boundaries when using grouped data. (Author/RM)

Many errors in ESL students' writing are caused by misleading cognates, words in the two languages which look alike, yet do not mean the same thing. (DD)

This paper presents a psychometric analysis of the criterion problem in neo-Piagetian concept development research. The evidence shows that false negative and false positive criterion errors have the same effect on the null hypothesis so that the criterion with the lowest error rate should be utilized.

This study tested Piaget's explanation of infants' perseverative error in manual search by comparing searches when the object was (1) hidden, (2) covered but visible, and (3) uncovered. Errors occurred under all three conditions, with conflict at a maximum when the object was hidden. (Author/JMB)
