For the past fifteen years, new techniques and methods, most particularly audio-visual ones, have made it possible to foresee a profound renewal in the training and retraining of teachers. To name some, the use of tape recorders, and then closed-circuit television, the production of anthologies on films, radio and television programmes, which make up an integral part of a system of training at a distance. In industrialised countries, these methods are very unequally used; in some of them, they do not even have as yet a system of retraining at a distance. Also conditions vary greatly according to the training institutes. Some only use the most traditional methods more or less perfected; others, well equipped with projectors of all sorts, laboratories and closed-circuit television, try to introduce really new methods and mediafor teaching. And lastly, some new procedures have hardly gone outside the research centres. 相似文献

A cohort of 71 pairs of twins was studied in a project which started within the decade 1965 to 1975. The total level of intelligence (global IQ) and the level of particular intellectual components have been examined annually since the twins were two years of age. The data were analysed by comparing monozygotic and dizygotic twins. The results revealed that high intelligence is influenced much more by hereditary than exogenous factors. Furthermore, there is an irregularity in the development of intellectual level from childhood to adulthood. Consequently, decision making about children cannot be carried out on the basis of a single IQ evaluation. A cluster analysis demonstrated the importance of hereditary factors not only on intellectual level, but also on the pattern of intellectual development. 相似文献
