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…

Age-appropriate modifications of the A-not-B task were used to examine 2-year-olds' search behavior. Several theories predict that A-not-B errors will increase as a function of number of A trials. However, the hierarchical competing systems model (Marcovitch & Zelazo, 1999) predicts that although the ratio of perseverative to nonperseverative…

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…

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…
