The present study investigated the effects of positive and negative GABA[subscript A] modulators under three different baselines of repeated acquisition in squirrel monkeys in which the monkeys acquired a three-response sequence on three keys under a second-order fixed-ratio (FR) schedule of food reinforcement. In two of these baselines, the…

Grammar instruction has long been a troubling issue for many language arts teachers. This collaborative research between an elementary classroom teacher and university faculty, based on the assumption that grammar is most effectively taught in reading and writing, looks into the short- and long-term effect of error-based grammar instruction on the…

Eighty blindfolded healthy female subjects participated in an active and a passive straight-ahead pointing task to study the estimation of the subjective sagittal middle in the presence or absence of an active haptic exploration. Subjects were to point straight-ahead with their left or right index finger starting from different right- or…

The present study examines 20 writing samples in English and Spanish selected from portfolios of first grade children at a bilingual school in Ecuador. Based on earlier findings that paragraphs composed in English and Spanish by children, adolescents and adults are different (Lux & Grabe, 1991; Montano-Harmon, 1991; Reid, 1990; Reppen &…

A possible role of the cerebellum in detecting and recognizing event sequences has been proposed. The present study sought to determine whether patients with cerebellar lesions are impaired in the acquisition and discrimination of sequences of sensory stimuli of different modalities. A group of 26 cerebellar patients and 26 controls matched for…

Four different age groups (8-9-year-olds, 11-12-year-olds, 13-15-year-olds and young adults) performed a spatial rule-switch task in which the sorting rule had to be detected on the basis of feedback or on the basis of switch cues. Performance errors were examined on the basis of a recently introduced method of error scoring for the Wisconsin Card…

This article used a writing sample that contained 27 sentence-level errors of the type found by corporate America to be annoying and bothersome. Five categories of errors were included in the sample: grammar, punctuation, spelling, writing style, and business communication concepts. Students in a written business communication course were asked…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

The consistency/variability of error substitution patterns may hold important implications for subgrouping children with speech disorders, as well as for relationships between learning and generalization patterns. There is a need to quantify and examine the range of consistency/variability within the speech disordered population as it relates to…

Two studies investigated the intrinsic and contextual difficulties of English spelling for native Haitian Creole-speaking children (NHCSs), and the effect of phonemic awareness on the achievement on beginning spellers. Each study had 20 NHCS kindergarten children as subjects. In the first, the subjects were trained in English phonemics (blending,…

The Integrated Quality Control Measurement Project (IQCMP) of the U.S. Department of Education measured the quality of awards distributed during the 1988-89 award year under the three major Title IV programs: the Pell Grant program, the Campus-Based programs, and the Stafford Loan program, in order to evaluate and improve the quality of the…

This study evaluated a partial-immersion program in French in Victoria, Australia, an area in which little research has been conducted to date. The program has operated at an elementary school since 1991 and is the first English/French program of its kind in Victoria. French is the language of instruction for at least 40 percent of classes, with…

A study compared the nature and frequency of faults and errors in reference list entries and direct quotes selected from 78 articles in 8 issues of the "American Educational Research Journal" (AERJ) with authors sampled from 10 previously studied journals. All departures from the original (additions, omissions, or changes) were labeled as either a…

A study of the acquisition of the auxiliary (tense, modal, perfect, and progressive) by 36 adult learners of English as a second language at three levels whose first languages were Arabic, Japanese, and Spanish is reported. The students were given three tests, on oral production, written production, and written reception. Nineteen verb structures…

In recent research, two qualitatively different classes of mental operations have been identified. The performance of one type of cognitive task requires attention, in the sense of mental effort, for its execution, while the second type can be performed automatically, independent of attentional control. Further research has shown that automatic…
