Education in different communication media takes place with functional differences that have consequences for the course of instructional interaction. In this paper, we examine instructional interaction among people using a computer-based electronic message system, contrasting it with conventional face-to-face discussion in a college level class. Interaction via the non-real time message system contained multiple “threads of discourse,” a higher proportion of student turns to teacher turns, and other deviations from the “initiation-response-evaluation” sequences usually found in face-to-face classroom interactions. Based on the results of our contrast, we describe ways to organize instruction using electronic message systems to take advantage of new properties and to avoid shortcomings of these new instructional media.  相似文献

Educational technology units, audio-visual aids centres or television services have been established in many British Universities during the present quinquennium. These have met with varied responses from academics, and several organizational patterns have emerged. This article sets out to describe the organizational structure and the range of services offered by the Educational Services in the University of Bath. The Service grew out of the amalgamation of several discrete and independent provisions within the University—projection services, a City-University television service, a unit in the School of Education and so on.Across the board involvement is achieved via a Senate Committee responsible for overall direction, credibility is established by the appointment of an existing academic staff member as director, and an internal bulletin provides the core of a communications system with the academics. Staff seminars on curriculum analysis and development, methods of evaluation and so on, backed up by occasional visiting speakers, provide theoretical backup to the practical and hardware services. An important aspect of the work of the Service is co-operation and co-ordination with the new University Library which has been designed to provide both book and non-book information services. Professor Austwick is the Chairman of the Senate Committee on Educational Technology, and Mr. Harris is the Director of Educational Services in the University.
Les services annexes de l'enseignement a l'Universite de Bath
Résumé Des services rassemblant les moyens techniques d'enseignement, ainsi que des centres audio-visuels ou télévisuels ont été créés dans de nombreuses universités anglaises ces dernières années. Ils ont suscité des réactions différentes de la part du milieu universitaire et, de ce fait, des formes d'organisation différentes sont apparues. L'article vise à décrire l'organisation et la gamme des services qui se rencontrent en cette matière à l'Université de Bath. Le Service des moyens pédagogiques est né de l'intégration de plusieurs services indépendants qui existaient au sein de l'Université: services de projection, de télévision, un groupe de l'Institut d'éducation etc.Les relations avec le Conseil sont assurées par un comité responsable de la marche générale des services; le sérieux de l'entreprise est garanti par la nomination comme directeur d'une personalité membre du corps universitaire; la publication d'un bulletin intérieur fournit un moyen de communication avec l'ensemble des universitaires. Des séminaires consacrés à l'analyse et à l'élaboration des filières d'études, aux méthodes d'évaluation des résultats et autres sujets semblables sont animés par des spécialistes invités et procurent une aide théorique aux services d'exécution technique. Un aspect important de l'activité du Service réside dans la coopération et la coordination avec la nouvelle bibliothèque de l'Université qui a été concue pour diffuser l'information, que celle-ci soit livrescue ou non. Le professeur Austwick est président du Comité pour la technologie de l'enseigement et M. Harris est directeur du Service des techniques d'enseignement à l'Université de Bath.

High rates of school failure have been reported for secondary school students, with boys presenting more schooling difficulties. The aim of this study was to investigate the association between school performance and family and psychological factors. A sample of 1315 male and female secondary school students was recruited from 54 classes randomly selected out of a total of 534 classes in the Greek region of East Macedonia and Thrace. School performance was measured dichotomously according to the final school results (pass or fail). Family and sociodemographic data were collected and psychological problems were measured using the Youth Self Report (YSR). Male gender, low socioeconomic status, low parental education and parental separation were all positively associated with school failure. Those who failed scored higher on the YSR problem scales than those who passed, and boys were more affected by adverse circumstances than girls. The results indicate that students, especially boys, with psychological problems and those coming from families of low socioeconomic and educational status are at high risk of school failure.  相似文献

Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks.  相似文献

Abstract

Traditional professional development is often characterized as being expensive, time consuming, and lacking impact. In contrast, online professional development provides greater flexibility and is becoming increasingly popular for school personnel. In this article, we report the process and outcomes of gathering feedback to adapt traditional in-person to online training differentiated for the participants to maximize utility, efficiency, and effectiveness in meeting the needs of key stakeholders. Focus groups were conducted with teachers, administrators, and other specialists to gather feedback on content as well as how online learning modules (OLMs) could be tailored to meet specific school site and team needs. We discuss our findings in the context of continuing efforts to improve general and specific professional development opportunities.  相似文献

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment. The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science. The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed. John Reveles is an assistant professor in the Elementary Education Department at California State University, Northridge. He received his Ph.D. from the University of California, Santa Barbara in 2005. Before pursuing his Ph.D., he worked as a bilingual elementary school teacher for 3 years. His research focuses on the development of scientific literacy in elementary school settings; sociocultural influences on students' academic identity; equity of access issues in science education; qualitative and quantitative research methods. Within the Michael D. Eisner College of Education, he teaches elementary science curriculum methods courses, graduate science education seminars, and graduate research courses. Gregory Kelly is a professor of science education at Penn State University. He is a former Peace Corps Volunteer and physics teacher. He received his Ph.D. from Cornell in 1994. His research focuses on classroom discourse, epistemology, and science learning. This work has been supported by grants from Spencer Foundation, National Science Foundation, and the National Academy of Education. He teaches courses concerning the uses of history, philosophy, sociology of science in science teaching and teaching and learning science in secondary schools. He is editor of the journal Science Education. Richard Durán is a Professor in the Gevirtz Graduate School of Education, University of California, Santa Barbara. His research and publications have been in the areas of literacy and assessment of English Language Learners and Latino students. He has also conducted research on after school computer clubs, technology and learning as part of the international UC Links Network. With support from the Kellogg Foundation, he is implementing and investigating community and family-centered intervention programs serving the educational progress of Latino students in the middle and high school grades.  相似文献

We analyzed how two basic electromagnetism textooks approach the concept of electric field. We limited our study to the reasons given in these textbooks for the introduction of the field representation and to how accurate, coherent, and complete these reasons are. Because many times historical reasons are intertwined with textbooks' explanations of physical phenomena, we used the historical evolution of the field representation to guide our analysis. The analysis shows that one textbook mixes up the historical and pedagogical reasons for the introduction of the concept of field. The other one presents a sketch that might lead students to understand the field and the action-at-a-distance views as supplementing each other.  相似文献

Forty-five abusive parents (40 mothers, 5 fathers) in treatment at a large, urban medical center's child abuse program were compared on 22 parent, child, and treatment variables posited to bear on reabuse. While no one variable by itself was strongly associated with reabuse, the data indicated that interactions involving several variables (e.g., income source, marital status, and the abuser's personal abuse history) significantly differentiated between reabusers and nonreabusers. Implications of the findings for research and clinical intervention are discussed.  相似文献
