For the past few years a discussion has been going on about the specific skills and knowledge a complete engineer should possess. Apart form this discussion, a separate debate has focused on the content of an engineer's education. This article is a combination of two joint papers (De Graaff and Ravesteijn 2000, Ravesteijn and De Graaff 2000) bearing on these respective subjects, presented by the authors at the SEFI 2000 conference in Paris. The demands from industry that engineers of the future will have to meet are summarized and related to characteristics of modern training methods. It is argued that a new view on the content of the engineer's education implies, at least to a certain extent, a new set of educational tools.  相似文献

For this study, information on Who Bullies Who was collected from 54 school classes with 918 children (M age = 11) and 13,606 dyadic relations. Bullying and victimization were viewed separately from the point of view of the bully and the victim. The two perspectives were highly complementary. The probability of a bully-victim relationship was higher if the bully was more dominant than the victim, and if the victim was more vulnerable than the bully and more rejected by the class. In a bully-victim dyad, boys were more often the bullies. There was no finding of sex effect for victimization. Liking reduced and disliking increased the probability of a bully-victim relationship.  相似文献

The effects of writing style upon mature older readers’ reading comprehension are considered. Two narrative historical selections, the first emotive and abstract and the second nonemotive and concrete, were employed. Miscue analysis was used to evaluate the efficiency with which each reader used reading strategies across the five systems that cue meaningful comprehension. Miscues were analyzed at the word, clause, sentence, and intersentence levels. In addition, interview schedules were employed to identify readers’ perceptions of preferred reading strategies and to permit a comparison with actual performance. The findings indicate that mature older readers are consistent in cue system utilization. A preference for the word cue system influenced both the use of cues from other systems and comprehension. Use of the word‐level cue system is inversely related to the use of the other available cue systems. Preference for cues within words also appears to be inversely related to comprehending effectiveness. The subjects’ perceptions of the reading process and their actual reading performance appeared to determine patterns of cue system use more clearly than did the differences in materials. As a result, those developing materials intended for use in programs with older persons should not only be concerned with the content and quality of those materials but also the skills and perceptions of those who will use the materials.  相似文献

ABSTRACT

An orthopedagogical method for teaching children with a depression is presented here. Relatively unknown in the English‐speaking world, orthopedagogy is a pedagogical discipline that is aimed at an entire action field. It does not target the child with handicap, but the entire problematic educational situation (PES). Orthopedagogy is the scientific study of assistance given to those concerned with a PES ‐ namely, the child, parents, brothers and sisters, grandparents, and so on. To break through a PES or to get rid of it, the orthopedagogician has to listen to the orthopedagogical request for help of the child and give an appropriate answer to it. On the basis of a theoretical model of Paul Gilbert, an orthopedagogic request for helping children with a depression was formulated. Gilbert's model offers a perspective derived from evolution theory and argues for the adoption of a bio‐psychological approach. Children with a depression request a warm and loving climate, an attractive and simple education situation and close involvement on the part of the educator. To answer that request, we set orthopedagogical action on two tracks. On track 1 (dialogical action) we try to break through the PES by asking the educator to over‐accentuate the pedagogical climate, the education situation and his/her own presentation. On track 2 (technical action) we designed an approach aimed at children aged between 6 and 12 years with a depression.  相似文献

In this paper we present a new methodology for detecting differential item functioning (DIF). We introduce a DIF model, called the random item mixture (RIM), that is based on a Rasch model with random item difficulties (besides the common random person abilities). In addition, a mixture model is assumed for the item difficulties such that the items may belong to one of two classes: a DIF or a non-DIF class. The crucial difference between the DIF class and the non-DIF class is that the item difficulties in the DIF class may differ according to the observed person groups while they are equal across the person groups for the items from the non-DIF class. Statistical inference for the RIM is carried out in a Bayesian framework. The performance of the RIM is evaluated using a simulation study in which it is compared with traditional procedures, like the likelihood ratio test, the Mantel-Haenszel procedure and the standardized p -DIF procedure. In this comparison, the RIM performs better than the other methods. Finally, the usefulness of the model is also demonstrated on a real life data set.  相似文献
