Composite reading scores obtained from parents of 125 reading-disabled children and 125 matched control children who participated in the Colorado Family Reading Study were used to test the validity of self-reported reading problems. Parents who reported that they encountered serious difficulty learning to read had significantly lower reading scores than did those who reported no positive history of reading problems. Moreover, this difference was larger for parents of reading-disabled children than for those of controls. Thus, parental self-reports provide a valid index of reading problems.  相似文献

This article reports the development of a new phenomenon in the United States described here as national media courses. Such courses use one of the mass media — television, newspapers, radio or magazines — as the essential means of instruction, but supplement the learning thus derived with additional readings and other studies. Usually there are several contact sessions with an instructor to enable students, who otherwise study independently, to meet and exchange ideas or have curricular or administrative questions answered authoritatively. This academic concept uses one of the media designed to reach mass audiences to enable independent learning at times and places of most convenience to the adult audience which they are designed to serve. National media courses are originated at the University Extension at the University of California, San Diego and several other institutions. They are designed to be offered as college courses by two- and four-year post secondary institutions throughout the nation. Nearly one-third have taken advantage of their availability and over fifty thousand students have taken part in a single national media course.
Zusammenfassung Dieser Artikel berichtet von der Entwicklung eines neuen Phänomens in den Vereinigten Staaten, das dort unter dem Namen national media courses bekannt geworden ist. Solche Kurse benutzen eines der Massenmedien — Fernsehen, Zeitungen, Radio oder Zeitschriften — als wichtigstes Unterrichtsmittel, ergänzen aber das dabei stattfindende Lernen durch zusätzliche Lektüre und andere Studien. Gewöhnlich finden etliche Kontaktsitzungen mit einem Instruktor statt, die die Studenten, die sonst unabhängig selbst lernen, befähigen sollen, sich zu treffen, und Gedanken auszutauschen oder sich Fragen des Curriculums oder die Verwaltung betreffend kompetent beantworten zu lassen. Dieses akademische Konzept benutzt eine für die Massenzuhörerschaft konzipiertes Massenmedium, um dem angesprochenen Kreis von Erwachsenen, für die es erdacht wurde, ein in Zeit und Ort angenehmes Lernen zu ermöglichen. National media courses kommen von der Fernabteilung der Universität von Kalifornien, San Diego, und einigen anderen Institutionen. Sie sollen als College-Kurse von postsekundären Institutionen mit drei- oder vierjähriger Studiendauer im ganzen Land angeboten werden. Beinahe ein Drittel der angesprochenen Institutionen hat sich dieser Möglichkeit bedient, und über fünfzigtausend Studenten haben an einem einzigen national media course teilgenommen.

Résumé Cet article rend compte du développement d'un nouveau phénomène aux Etats-Unis décrit ici comme cours nationaux à l'aide de moyens d'information de masse. De tels cours se servent de l'un des moyens d'information de masse — la télévision, les journaux, la radio ou les magazines — comme procédé essentiel d'instruction, mais complètent l'apprentissage qui en résulte à l'aide de lectures additionnelles et d'autres études. Il y a habituellement plusieurs séances de contact avec un maitre permettant aux étudiants, qui autrement étudient indépendamment, de faire connaissance et d'échanger des idées ou de recevoir une réponse péremptoire aux questions administratives et à celles concernant les curricula. Ce concept académique se sert de l'un des média conçus pour atteindre les audiences des masses, de sorte à permettre un apprentissage indépendant, à des heures et des endroits convenant le mieux à l'audience adulte qu'ils se proposent de servir. Les cours nationaux à l'aide de média tirent leur origine de l'Extension Universitaire à l'Université de la Californie, San Diego et de plusieurs autres institutions. Ils sont conçus pour être présentés comme cours de collège par des institutions post secondaires d'une durée de deux à quatre ans à travers toute la nation. Presque un tiers a déjà tiré profit de leur disponibilité et plus de cinq mille étudiants ont pris à un cours unique national à l'aide de média.

Why do children learn in different ways: some are good students who show interest and zeal, while others are lazy and have to be taught against their will? Why do schools have over- and underachievers? Of course, there are a multitude of reasons. But almost 50 years ago it was shown using large data sets that families with high socioeconomic status are more likely to have children who are good students. Of course, there are many examples of successful students from poor families. However, they tend to be the exception to the rule. The certainty of success in school increases with rising socioeconomic status.  相似文献

Relations between self-reported parental reactions to children's negative emotions (PNRs) and children's socially appropriate/problem behavior and negative emotionality were examined longitudinally. Evidence was consistent with the conclusion that relations between children's externalizing (but not internalizing) emotion and parental punitive reactions to children's negative emotions are bidirectional. Reports of PNRs generally were correlated with low quality of social functioning. In structural models, mother-reported problem behavior at ages 10-12 was at least marginally predicted from mother-reported problem behavior, children's regulation, and parental punitive or distress reactions. Moreover, parental distress and punitive reactions at ages 6-8 predicted reports of children's regulation at ages 8-10, and regulation predicted parental punitive reactions at ages 10-12. Father reports of problem behavior at ages 10-12 were predicted by earlier problem behavior and parental distress or punitive reactions; some of the relations between regulation and parental reactions were similar to those in the models for mother-reported problem behavior. Parental perceptions of their reactions were substantially correlated over 6 years. Some nonsupportive reactions declined in the early to mid-school years, but all increased into late childhood/early adolescence.  相似文献

The present paper is divided into eight sections:introduction,the global diffusion of English,perceptions of the new varieties,the issue of intelligibility,features that cause unintelligibility,need for a broader pragmatics,and pedagogical impli- cations,and conclusion,followed by the references.Not surprisingly,the global spread of English has generated varying perspec- tives on the nature and functions of its acculturated varieties.Broadly speaking,the debate has divided scholars into two camps holding diametrically opposing views on the multiple versions of English.On the one hand,some scholars view variations as symp- toms of linguistic degeneration and deterioration;on the other hand,some scholars legitimize them as inevitable manifestations ne- cessitated by the demands of the new cultural contexts.The normative view of the former camp stems,at least partly,from the problems the new forms of English pose in terms of international intelligibility.It is in this context that the paper examines the traditional,one-sided,native speaker-centred idea of intelligibility and the recent two-sided view of intelligibility that places the onus on both the native speaker and the non-native speaker.The argument of the latter camp is based on the premise that the new varieties require a broader pragmatic framework,because universal pragmatics is inadequate to describe them satisfactorily. Thus,the camp advocates a need for a language specific pragmatics,and a comparative pragmatics,in addition to the traditional universal pragmatics.Logically,the debate on phonological,lexical,grammatical,and discourse structure variations,and their le- gitimacy has prompted English language teaching specialists to have a fresh look at the goals and objectives of teaching English in the countries of the outer and expanding circles,and accordingly prioritize the teaching of national and regional varieties over that of the so-called native varieties.Thus,the paradigms of independence and centrality of the new varieties are replacing the paradigms of their dependence and marginality.  相似文献

This article serves as an introduction to log-linear analysis, a technique used in the analysis of qualitative data arranged in multidimensional contingency tables. The steps involved in log-linear analysis are presented in the context of an investigation of a personality characteristic of a group of counselor trainees. The references cited and supplemental readings allow interested readers to pursue the topic further.  相似文献

Selecting the correct method for routine analysis by ‘method evaluation’ is an important component of quality assurance. It is a step-wise procedure that evaluates various analytical parameters like accuracy, precision etc of the given method. Finally reference intervals are established for selected population. We evaluated an enzymatic method for serum creatinine. The results show that it is an acceptable method based on the above mentioned criteria.  相似文献

Circulating levels of gonadotropins (FSH,LH), prolactin (PRL), estradiol and progesterone were measured by radioimmunoassay in the sera of 60 patients with histopathologically proven breast cancer. 30 patients belonged to the post and 30 to the premenopausal group. 30 healthy women, 15 each in the pre and post menopausal groups served as controls for the study. Prolactin was elevated in 33% and 26% of pre and post menopausal breast cancer patients respectively. Lower levels of estradiol and progesterone were observed during the luteal phase of the menstrual cycle in premenopausal breast cancer patients. Among postmenopausal patients with breast cancer, LH was elevated in 32%, FSH in 15% and estradiol in 30% of the patients studied.  相似文献
