Mnemonic artwork-learning strategies: Helping students remember more than “Who painted what?”     

Todd M. Franke  Joel R. Levin  Russell N. Carney 《Contemporary educational psychology》1991,16(4)

In two experiments, a recently devised mnemonic strategy was examined in the context of college students recalling the theme and contents of various paintings. With the painting-artist mnemonic strategy: (a) the artist's name is first recoded as a more concrete proxy; and (b) the recoded stimulus is then related to a prominent feature of the painting. Previous research has demonstrated that such a strategy enhances students' recall of artist names when cued with the associated paintings. The present study extends those findings by demonstrating that the strategy similarly facilitates students' recall of paintings and painting information when cued with the associated artist names. Of three different mnemonic variations included, one that incorporates a verbally described mnemonic interaction into the painting proved most effective. Suggestions for future research and educational implications are included in the discussion.  相似文献   

An exploratory investigation of the effects of a cultural orientation programme on the psychological well-being of international university students     

N. J. Mckinlay  H. M. Pattison  H. Gross 《Higher Education》1996,31(3):379-395

Culture shock has been identified as a psychological reaction to a change in cultural environment. The main symptoms of culture shock are reported to be psychological disturbance, a negative reaction to the new surroundings and a longing for a more familiar environment. Research has identified culture shock as a component in the difficulties that international students face when studying in another country. One way that institutions of higher education have responded to these difficulties is to provide initial cultural orientation. In the study reported here, a group of post-graduate students who had participated in a study skills and cultural orientation course at a British university were compared with a group who had not. Contrary to the research hypothesis, the group that took part in the orientation course were significantly more homesick and reported more psychological difficulties. The overall findings cast doubt on the received view of culture shock as it affects international students. They suggest that culture shock is exacerbated by personal and social factors and this has implications for the way that international students may be helped through the experience.  相似文献   

Early Childhood Services in Ireland     

Eilis Hennessy  Nóirín Hayes 《International Journal of Early Years Education》1997,5(3):211-224

This paper gives background information on early childhood services in Ireland and presents the results of a survey of the preschool experiences of 1065 children. The results of the survey suggest that the majority of children experienced some form of early childhood service before starting school. The most common service was a playgroup although a significant proportion of the children had experienced home‐based care with a relative or family day care provider. The implications of the findings for the development of a policy on early childhood services are discussed.  相似文献   

Enrollment strategies in early home visitation to prevent physical child abuse and neglect and the "universal versus targeted" debate: a meta-analysis of population-based and screening-based programs.     

N B Guterman 《Child abuse & neglect》1999,23(9):863-890

OBJECTIVE: Seeking to discern optimal programmatic strategies and inform the "universal versus targeted" debate in early home visitation services to prevent physical child abuse and neglect, a meta-analysis was conducted examining enrollment approaches in early home visitation studies and their reported outcomes. METHOD: Quantitative meta-analytic techniques were used to compare effect sizes from 19 controlled outcome studies across screening-based and population-based enrollment strategies. Effect sizes were calculated on protective services data and on child maltreatment related measures of parenting. RESULTS: On protective services report data, population-based studies reported a weighted mean effect size attributable to early home visitation of +3.72%, in comparison to -.07% for screening-based studies. On child maltreatment related measures of parenting, population-based studies reported a weighted mean effect size (r) attributable to early home visitation of +.092, in comparison to +.020 for screening-based studies. CONCLUSIONS: The findings indicate that population-based enrollment strategies appear favorable to screening-based ones in early home visitation programs seeking to prevent physical child abuse and neglect. It may be that psychosocial risk screens serve to enroll higher proportions of families for which early home visitation services are less likely to leverage change, and to exacerbate a mismatch between early home visitation service aims and family needs.  相似文献

Validity of self-reported reading disability by parents of reading-disabled and control children     

Sadie N. Decker  George P. Vogler  J. C. Defries 《Reading and writing》1989,1(4):327-331

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   

The extension of higher education by mass media     

M. N. Chamberlain 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1977,23(2):191-203

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.
