The study investigated the degree to which errors of scaling and selection depress the linear relationship and whether the reduction in the magnitude of r differs with the type of error. Results indicated that various scaling errors caused considerable discrepancy in the measurement of underlying relations, but the effect of non-normality was…

The Spelling Error Detection Correction Project completed at Chemical Abstracts Service, which extracted over 50,000 misspellings from approximately 25,000,000 words of scientific and scholarly text, shows that expected incidence of misspelling is 0.2 percent, and most misspellings are "typos," 90 percent of which are unlikely to be…

The speech of five stutterers ranging in age from 3 years, 10 months to 5 years, 7 months was analyzed to determine the types of loci of stutterings. The results related to the hypothesis that early stuttering represents mainly a type of difficulty in either the formulaton or the execution of syntactic units. (Author)

Looked at errors produced by 155 students developing spreadsheets while they were working alone, in groups of two, and in groups of three. Determined that synchronous team spreadsheet development is promising but expensive and does not seem to be a cure-all for spreadsheet errors. (JOW)

Two-year-olds' difficulty with rule execution was examined through one of six tasks: a task assessing knowledge about a series of items, a deductive card sort requiring the use of knowledge to sort items by rules, and four modifications of the card sort. Found that the toddlers performed better on the knowledge task than the other tasks. (MDM)

Reviews research on inductive reasoning errors, including seeing patterns or relationships where none exist, neglecting statistical regression, overgeneralizing unrepresentative data, and drawing conclusions based on incomplete decision matrices. Considers "false consensus effect," through which associations with like-minded people lead one to…

Three experiments examined 3- to 4-year olds' judgments about physical representations which no longer matched their references. Results showed that children tended to misidentify the name of a sticker in a written list to match a change to its referent. Children's incorrect judgments indicated that realist errors to external representations…

Fifteen participants unfamiliar with mathematical operations relative to reflections and vertical and horizontal shifts were exposed to an introductory lecture regarding the fundamentals of the rectangular coordinate system and the relationship between formulas and their graphed analogues. The lecture was followed immediately by computer-assisted…

This qualitative case study investigates Chinese university English in the context of foreign language (EFL) learners' attitudes about video-aided instruction (VAI), video recording instruction, and mobile phone instruction (learning technologies). When I was working as an English teacher in Mainland China, several instructors and students stated…

Studies that examine the impacts of education interventions on key student, teacher, and school outcomes typically collect data on large samples and on many outcomes. In analyzing these data, researchers typically conduct multiple hypothesis tests to address key impact evaluation questions. Tests are conducted to assess intervention effects for…

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…
