Educational Television in Portugal

Educational Television is a special department of Telescola, an official institution dependent on the Instituto de Meios Audio-Visuais de Ensino (I.M.A.V.E.—Institute of Audio-Visual Aids in Education), which was created in the Portuguese Ministry of Education at the end of 1964.     

The Complex Model of Television Viewing and Educational Achievement

Abstract

Six studies containing data obtained from over 1 million students in elementary, intermediate, and high school were meta-analyzed to examine the relationship between amount of television viewing and educational achievement. The findings led to the formulation of the complex viewing—achievement model. According to the model, the function relating achievement to viewing can be described as an inverted check mark. For small amounts of viewing, achievement increased with viewing, but as viewing increased beyond a certain point, achievement decreased. That function was found for each of the 3 ages studied, but optimal viewing time—the apex of the function—was different at each age and decreased with the age of the students.

The Use of Dynamic Assessment by Educational Psychologists in the UK

Training in Dynamic Assessment (DA) was rarely available in the UK until 1994. This is the first study to explore the outcomes of its availability in terms of the practice of DA and perceptions about it among educational psychologists (EPs). One hundred and nineteen EPs, who had taken positive steps to inform themselves about DA by undertaking some degree of training or by joining a DA interest group, were surveyed to explore the extent of their initial training in DA, subsequent use of it and issues of implementation. Overall, the 88 responses (74%) received suggest, among those surveyed, widespread awareness of DA as a model of cognitive assessment and positive attitudes to it, coupled with a low level of implementation. The low level of use was frequently attributed to insufficient training in DA, to lack of time due to other assessment priorities, often set by the local education authority, and to lack of the ongoing expert support felt to be necessary to maintain use of a demanding form of assessment. The authors take the position that the EP's repertoire would be enriched by improved knowledge of and training in DA. The research raises important issues for cognitive assessment and raises the broader question whether there is a need for the more proactive involvement of educators in enhancing the cognitive functioning of children.     

Early Formative Evaluation of Educational Television

This article examines the incorporation of formative evaluation in the early stages of ETV programme development, and argues that Self‐Formative Evaluation, an evaluation system conducted by the developers of an ETV programme and in‐house evaluators, should be conducted. A list of criteria that can be used in this evaluation process is given     

Educational Television in the Nineties: a global survey

This article describes the results of a global survey about the most critical issues facing educational television in this decade. Over 100 responses were received, and every continent was represented. Reactions indicated that the most critical problems were associated with limited funding, inadequate staffing, outdated equipment, insufficient broadcasting time and declining levels of government support. Lack of equipment in schools and insufficient teacher training were also cited as major concerns. Solutions to these problems were also solicited on the survey. There were some interesting suggestions, which included more corporate partnerships, international co‐productions, ‘media literacy’ training for teachers, and the establishment of a global educational television consortium.     

Educational Television in Israel: spotlight on the future

The author was based at the Educational Television Centre in Tel‐Aviv with a remit to study the development of educational television in Israel from its inception in 1966. The article briefly discusses the political and technological factors which led to the development of an educational television channel in Israel. At that time television in Israel consisted solely of educational television broadcasts in the mornings and afternoons. This was extended when the Israeli Broadcasting Authority started to broadcast on the one Israeli channel in the evening slot. The article concentrates on the recent development of educational television and its bid for a new niche in the constellation of Israeli broadcasting. Inevitably the development and future of educational broadcasting is intimately linked with Israel's religious and political schisms and its military and cultural preoccupations. At the moment Israel still only has one television channel, although test programming has been piloted on a second channel. This article explores the future options open to the Educational Television Centre in the context of satellite and cable broadcasting and the development of a second channel. Evidently the factors affecting the future of broadcasting in Israel are not dissimiliar from those which now face the UK, given the publication of the 1988 White Paper on Broadcasting
