This paper critiques Wolfgang, Figlio, and Sellin's "Delinquency in a Birth Cohort," (1972) which is the analysis of the recorded delinquent careers of a cohort of nearly 10,000 boys in Philadelphia, by outlining the consequences of an inadequate and cursory use of tabular analysis. (Author/RM)

This experiment attempted to discover under what circumstances, if any, children use whole words, syllables, letter clusters, or letters as units during reading. The results indicated that syllables and letter clusters are probably not processed as units for any type of word, but there was slight evidence that letters may function as units,…

This study was designed to replicate and extend Roberts' (1968) efforts at classifying computational errors. 198 elementary school students were administered an 84-item arithmetic computation test. Eight types of errors were described which led to several tentative generalizations. (Editor/RK)

Examines perspectives on language transfer in the light of a body of data regarding a beginning learner of French whose native language was English but who also had some knowledge of Irish, Latin, and Spanish. (Author/CB)

Searched article, book, and dissertation entries in reference lists in one volume year for two counseling journals, for accuracy. Found 44.9 percent of the verified references contained at least one error. Some errors could be explained as typographical. Concludes that with reference list preparation, writers in the counseling field seem to be…

Based on data from two experiments, this article attempts to assess degree to which people differ in interpretations of questions referring to library services and the implications for interpreting survey results. Sources of error in questionnaire research--sampling, response (question interpretation, response decision, category choices)--are…

Reports a class exercise which requires students to recalculate the Chi-squares, t-tests, and one-way ANOVAs found in published psychological research articles. Describes students' reaction to the exercise and provides data on the 13% error rate they discovered. (Author/JDH)

Children's mental performance was studied in the context of arithmetic word problem solution. Response latency and error data indicated subtraction was more difficult than addition. Understanding children's problem solutions in terms of flexible strategy use and the fact that many errors have a systematic basis are important in studying children's…

Several examples of mathematical diagnosis using microcomputer software are presented, with possible future considerations suggested. Three limitations of the software are discussed. (MNS)

Examined performance and error patterns of 50 bilingual Mexican-American third through fifth graders on the Expressive One-Word Picture Vocabulary Test (EOWPVT) and the Peabody Picture Vocabulary Test-Revised (PPVT-R). The EOWPVT had adequate concurrent validity with PPVT-R. On both tests, scores were almost two standard deviations below normative…

This excerpt from "Managerial Engineering: Techniques for Improving Quality and Productivity in the Workplace" describes the development, objectives, and use of On-Error Training (OET), a method which trains workers to learn from their errors. Also described is New Joharry's Window, a performance-error data analysis technique used in…

The performance of 60 fourth form pupils who had been taught to solve algebraic equations by the algorithmic or flow chart method was studied. A sizeable number of pupils were not using the flow chart method. Other types of errors are noted. (MNS)

Following an experiment which revealed that production of grammatically correct sentences and correction of grammatically problematic sentences in French are essentially different skills, a progressive training method for finding and correcting grammatical errors was developed. (MSE)

Evidence was collected to support previous research findings that children prefer quantitative to formal methods of solving linear equations. They find formal methods difficult. How to help them become more receptive to learning formal methods is discussed. (MNS)

In comparative judgments of two stimuli separated by a time interval, there is often a systematic asymmetry (time-order error). From a review of the literature it is concluded that the time-order error should be classified as a perceptual phenomenon that can be predicted with adaptation-level theory and sensation weighting.
