The conventional approach for testing the equality of two normal mean vectors is to test first the equality of covariance matrices, and if the equality assumption is tenable, then use the two-sample Hotelling T[superscript 2] test. Otherwise one can use one of the approximate tests for the multivariate Behrens-Fisher problem. In this article, we…

A traditional distance learning system requires supervisors or teachers always available on online to facilitate and monitor a learner's progress by answering questions and guiding users. We presents an English chat room system in which students discuss course contents and ask questions to and receive from teachers and other students. The…

36 Saudi EFL freshmen students took a listening-spelling test in which they filled out 100 blanks in a dialogue. Results indicated that 63% of the spelling errors were phonological and 37% were orthographic. It was also found that the subjects had more phonological problems with whole words but more orthographic problems with graphemes. Some of…

The detection of errors is known to be associated with two successive neurophysiological components in EEG, with an early time-course following motor execution: the error-related negativity (ERN/Ne) and late positivity (Pe). The exact cognitive and physiological processes contributing to these two EEG components, as well as their functional…

This article is based on results of a quasi-experimental study in which the efficacy of the strategies approach for reviewing grammar and punctuation concepts was assessed in a business communication course. The control group studied rules-based review materials; the treatment group studied strategies-based review materials. On the three sets of…

We examined the performance of sequential bilingual children with and without Specific Language Impairment (SLI), who had Spanish as an L1 and English as their L2, on an auditory non-word repetition task using Spanish phonotactic patterns. We also analyzed the accuracy with which this task distinguished these children (according to children's and…

Patients with lesions of the left hemisphere often suffer from oral-facial apraxia, apraxia of speech, and aphasia. In these patients, visual features often play a critical role in speech and language therapy, when pictured lip shapes or the therapist's visible mouth movements are used to facilitate speech production and articulation. This demands…

Canonical analysis is frequently used in studies of relationships between sets of variables which are difficult to measure accurately, partly because of the true nature of the data and partly because of errors associated with the measurement instruments. Meredith's solution to the fallible data problem is examined. (Author/BJG)

This paper discusses and provides some preliminary data on errors in APL programming. Data were obtained by analyzing listings of 148 complete and partial APL sessions collected from student terminal rooms at the University of Alberta. Frequencies of errors for the various error messages are tabulated. The data, however, are limited because they…

The study compared five adult stutterers' and five adult nonstutterers' fluent speech patterns produced during one nonshadowed reading and two speech-shadowing conditions (immediate repetition of a heard message). Among results were that stutterers produced fewer speech production errors than nonstutterers during shadowing conditions. (Author/DB)

Error analysis is proposed as a means to supplement diagnostic techniques with exceptional children. A purpose and definition of error analysis are provided. Also, procedures to use error analysis are explained along with basic guidelines to prevent abuse of error analytic techniques. (Author/CL)

A method of constructing a check digit for nonconventional chemical codes is described. (5 references) (Author)

Analysis of results for 1960, 1965, and 1970, and more recent data presage a growing gap between the projected female labor force and its actual size. (Editor)
