Current initiatives designed to develop stronger international co-operation between guidance services within the European Community are outlined. The implications of extending the Community to cover other European countries are discussed. The issue is raised of whether a common European approach to guidance is likely to emerge, and whether it is likely to differ from American approaches. Adapted and updated version of a paper presented at the International Conference of the International Association for Educational and Vocational Guidance held at the University of Lisbon, Portugal, on 9–13 September 1991.  相似文献

The evolution of ICT, and the ways in which it is currently used in the delivery of career information and guidance services, are examined. Such systems have the potential both to expand and to restrict access to career information and guidance. Ways in which ICT can complement and/or be integrated with other ways of providing career services are explored. Finally, a number of key policy issues relating to the role of ICT in national and regional career information and guidance systems are identified, including issues relating to funding and quality assurance. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

Foundational issues in evolution education   总被引:1,自引:0,他引:1  
There is a great need for effective evolution education. This paper reviews some of the evidence that demonstrates that need and analyzes some of the foundational semantic, epistemological, and philosophical issues involved. This analysis is used to provide a functional understanding of the distinction between science and non-science. Special emphasis is placed the scientific meaning of the terms theory, hypothesis, fact, proof, evidence, and truth, focusing on the difference between religious belief and acceptance of a scientific theory. Science is viewed as theologically neutral and as not mutually exclusive from religion. Finally, a number of practical recommendations to the classroom biology teacher are presented.  相似文献

Parameters pertaining to information processing by human beings have, in the past, been determined by learning and memory experiments with nonsense syllables, number sequences, etc. However, in the real world we are concerned with the processing of meaningful information, not senselles texts. Therefore, the determination of subjective information directly from meaningful material becomes extremely important in the instruction-learning process.This study derives an equation for predicting the subjective textual information contained in a text of material written in the English language. Specifically, this investigation describes, by a mathematical equation, the relationship between the subjective information content of written textual material and the relative number of errors committed by a learner when asked to predict, letter by letter, the content of given textual material. This relationship shows that the subjective information of a given text for a specific learner is directly proportional to the number of wrongly guessed signs made by that learner. This is expressed mathematically by% MathType!MTEF!2!1!+- % feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn % hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr % 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9 % vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x % fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamysaiabg2 % da9iaaiodacaGGUaGaaGymaiaabccacaWGfbaaaa!3B57! \[ I = 3.1{\rm{ }}E \] 0935 0212 VWhere: I = Information in bits E = Number of wrongly guessed signsThe application of Shannon's guessing procedure (1951) in this study permits the measurement of the subjective information of a given text for a specific learner. Unlike senseless texts, the subjective information of a meaningful text varies from learner to learner. Therefore, the derived equation permits the measurement of information in terms of a value that is dependent not only upon the inherent qualities of the subject matter, but also upon the internal state of the learner.The derived equation for the English language is then compared to an equation derived by Weltner (1967) for the German language and found to be remarkably similar.This work was, in part, supported by United States Air Force Contract F41609-71-C-0027 entitled Flying Training Research on Airborne and Ground Training Systems, and a research grant from Arizona State University.  相似文献

The transfer of children from primary school to secondary school has long been seen as a problematic area. The National Curriculum was depicted as offering a solution to some of the transfer problems by providing for curriculum continuity across the primary-secondary divide. This paper reports the results of a study of curriculum continuity in one subject, history, now that a National Curriculum has been in place for several years. It reports that teachers continue to see problems with the transfer and that secondary school teachers still incline to a ‘fresh start’ approach to year 7 pupils. There is also some evidence of a lack of curriculum consistency within the secondary schools involved in the research, there are differences between primary and secondary schools in the range of teaching and learning methods employed, there is some decline in pupils’ ratings of their experience of secondary education across year 7 and there are signs of some gender differences in these ratings. The conclusion is that there is a case for saying that the new arrangements have not alleviated the problems associated with the transfer.  相似文献
