The relationship between WISC-R subtest scores and Verbal, Performance, and Full Scale IQs was investigated for a sample comprised of rural Appalachian children. The sample was comprised of both white and black children who might be described as culturally different by virtue of low family income and residence in the mountainous areas of Virginia and North Carolina. Data analysis consisted of computing product-moment correlations (rs) between each of the ten subtests and the Verbal, Performance, and Full Scale IQs. Correlations between individual subtests and the FS IQ ranged from.49 through.63, but none of the differences between these rs were large enough to attain significance. Correlations between the verbal subtests and Verbal IQ ranged from.64 for Comprehension up to.78 for Vocabulary. For the performance subtest, the rs ranged from.54 between Coding and the Performance IQ up to.72 for Object Assembly. 相似文献

The Survey of Reading Attitudes was administered to 84 normal and 116 disabled readers from the intermediate grades, and a discriminate function analysis was performed on their scores for the eight dimensions of reading attitudes measured by the Survey. The findings indicate that Expressed Reading Difficulty, Reading as Enjoyment, and Reading Group are the three variables that discriminate between these two groups. In comparison with normal readers, disabled readers are more likely to feel negatively about their reading group, less likely to see themselves as pursuing reading for its intrinsic value, and more likely to perceive of themselves as having difficulty with reading. However, the extent to which these findings can be generalized beyond the present sample of white Appalachian students must be established through future research. 相似文献

Any instrument designed to measure broad cognitive ability is expected to correlate substantially with valid measures of academic achievement. This report describes an investigation designed to evaluate the relationship between the Cognitive Levels Test, a newly available instrument, and two tests of academic achievement that have been widely used for nearly two decades: the Woodcock Reading Mastery Tests and the KeyMath Diagnostic Arithmetic Test. The study included children in grades K-2 who were enrolled in a remedial summer school program. The results showed the Cognitive Levels Test (Cognitive Index) to be rather highly correlated with the KeyMath Diagnostic Arithmetic Test Total score (r=.72) and moderately correlated with the Woodcock Reading Mastery Tests Total Reading score (r=.55). A repeated measures analysis of variance comparing standard scores for the Cognitive Levels Test with those of the Woodcock Reading Mastery Tests indicated few mean differences between the two sets of scores. Implications concerning the validity of the Cognitive Levels Test were discussed. 相似文献

ABSTRACTAmid ongoing disruption, discourse about journalism increasingly emphasizes innovation within the newsroom and the rise of entrepreneurial initiatives outside it. This article uses the concept of interpretive repertoires to explore how students enrolled in journalism programmes in Britain and the Netherlands understand innovation and entrepreneurialism in relation to changing industry circumstances and long-standing conceptualizations of occupational norms and behaviours. We find shared repertoires that embrace technological change, but generally within an acceptance of traditional normative practice. 相似文献

Most students enter their first university physics course with a system of beliefs and intuitions which are often inconsistent with the Newtonian frame of reference. This article presents an experiment of collaborative learning aiming at helping first-year students in an engineering programme to transition from their naïve intuition about dynamics to the Newtonian way of thinking. In a first activity, students were asked to critically analyse the contents of two video clips from the point of view of Newtonian mechanics. In a second activity, students had to design and realise their own video clip to illustrate a given aspect of Newtonian mechanics. The preparation of the scenario for the second activity required looking up and assimilating scientific knowledge. The efficiency of the activity was assessed on an enhanced version of the statistical analysis method proposed by Hestenes and Halloun, which relies on a pre-test and a post-test to measure individual learning. 相似文献

In slo-pitch softball, the ball is delivered in an arc trajectory with a moderate velocity; hence, batters have time to adjust their stride technique based on the pitched ball location. The purpose of this study was to examine the influence of stride technique and pitched ball location on the mechanics of slo-pitch batting. A two-way ANOVA of two locations of pitch (inside and outside) x three strides (open, parallel, and closed) repeated measure study was conducted in this study. The results showed that the stride technique and pitched ball location did not have a consistent impact on the participants across different batting conditions, so the study recommends slo-pitch batters to explore different stride techniques when striking the ball. Further, to better understand the generalizability of the findings, the results indicated that participants were quite homogeneous as a group. Hence, coaches and educators may apply the findings from this study to other players with similar skill level. 相似文献

This article describes how communal aspects of faith find their way back into the lives of adolescents. The communal aspects of faith within individualized societies need more attention. It seems that with the current emphasis on individual faith, the intrinsic power of communal aspects of faith has been lost. This study shows that informal communities of adolescents—faith tribes—can restore the individual–communal balance in faith development. Youth ministry should encourage adolescents and tribal leaders to be aware of the faith possibilities of tribes. 相似文献

Experimental models of education that incorporate the mother tongue of immigrant children into the structure of their curricula constitute obvious cases-in-point for assessing the validity of bilingual or multilingual education for such children. The present case study of one such model, the so-called Foyer Bicultural Education Project of Brussels, is intended to shed some light on the relationship between formal mother-tongue training and the development of global language proficiency in minority-language children. Since this particular case-in-point involves three languages — Italian (the mother tongue), Flemish and French — it is especially interesting with regard to the validity of the so-called interdependence principle, as formulated by Cummins (1979). The findings presented here confirm Cummins' principle that the development of literacy in the mother tongue is a determinant of global language proficiency in minority-language children.
Zusammenfassung Versuchsweise eingeführte Erziehungsmodelle, die die Muttersprache von Einwandererkindern in die Struktur ihrer Curricula einarbeiten, stellen ganz offensichtlich Beispiele dar, die es ermöglichen, eine Daseinsberechtiging für die zwei- oder mehrsprachige Erziehung solcher Kinder zu etablieren. Die vorliegende Untersuchung, das sogenannte Foyer bikulturelle Erziehungsprojekt aus Brüssel soll die Beziehung zwischen formaler Muttersprachenausbildung und der Entwicklung globaler Sprachkompetenz bei Kindern mit Minoritätensprachen erläutern. Da der vorliegende Fall drei Sprachen betrifft — Italienisch (als Muttersprache), Flämisch und Französisch — ist er besonders interessant im Hinblick auf die Gültigkeit der sogenannten Interdependenz-Hypothese, die 1979 von Cummins formuliert wurde. Die hier vorgestellten Ergebnisse bestätigen Cummins Hypothese, daß die Entwicklung der Literalität in der Muttersprache ein Determinant der globalen Sprachkompetenz bei Kindern mit Minoritätssprachen sei.
Résumé Les modèles expérimentaux d'enseignement qui incorporent la langue maternelle d'enfants immigrants dans leurs programmes d'étude constituent des exemples évidents d'évaluation de la validité de l'enseignement bilingue ou multilingue pour ces enfants. La présente étude de cas sur un modèle de ce genre, le Projet Foyer d'Education Biculturelle de Bruxelles, vise à apporter quelques éclaircissements sur la relation entre l'apprentissage formel de la langue maternelle et le développement de la compétence linguistique globale chez les enfants appartenant à une minorité linguistique. Du fait que cet exemple spécifique comprend trois langues — l'italien (langue maternelle), le flamand et le français — il est particulièrement intéressant quant à la validité de ce que l'on appelle le principe d'interdépendance, tel qu'il a été formulé par Cummins (1979). Les résultats qui sont présentés ici confirment le principe de Cummins selon lequel le développement de l'alphabétisme qui s'appuie sur la langue maternelle détermine la compétence linguistique globale d'enfants appartenant à une minorité linguistique.相似文献

The combined influence of maturation, ripening, and climate on the profile of bioactive compounds was studied in banana (Musa acuminata, AAA, Cavendish, cv. Grande Naine). Their bioactive compounds were determined by the Folin-Ciocalteu assay and high-performance thin layer chromatographic (HPTLC) method. The polyphenol content of bananas harvested after 400 degree days remained unchanged during ripening, while bananas harvested after 600 and 900 degree days exhibited a significant polyphenol increase. Although dopamine was the polyphenol with the highest concentration in banana peels during the green developmental stage and ripening, its kinetics differed from the total polyphenol profile. Our results showed that this matrix of choice (maturation, ripening, and climate) may allow selection of the banana (M. acuminata, AAA, Cavendish, cv. Grande Naine) status that will produce optimal concentrations of identified compounds with human health relevance. 相似文献
