One hundred and sixty college students read three fictitious biographical passages according to either imagery-mnemonic or no-strategy control instructions. In one mnemonic condition, subjects formed separate images involving each biographical name and its associated facts: in another mnemonic condition, the biographical name and its associated facts were integrated within a single composite image. Relative to an interference-control condition, integrated mnemonic subjects recalled more factual information, whereas separate mnemonic subjects did not. In addition, the recall of integrated mnemonic subjects was statistically no different from that of a noninterference control condition, whereas the recall of separate mnemonic subjects was lower. Both theoretical and educational implications of the results are discussed. The first author’s contribution to this work was supported by an Organized Research Grant from the Graduate School of Illinois State University. The second author’s contribution was supported by the National Institute of Education under Grant No. NIE-G-81-0009 to the Wisconsin Center for Education Research and was facilitated by a Romnes Faculty Fellowship from the Graduate School of the University of Wisconsin, Madison.  相似文献

Mathematics has always played an important role in the education of engineers and production managers. At the present time, the importance of mathematics has increased significantly and it is quite natural that in universities around the world engineering students are taking courses in mathematics which constitute, as a rule, a significant portion of their programme. At the same time, however, the mathematical education of the engineer is far from ideal and its improvement deserves the closest scrutiny. The present article deals with several general aspects of this problem.  相似文献

Twenty domestic Muscovy ducks were trained to traverse a runway for food reward. Subjects were then randomly assigned to treatments. In one treatment, subjects received six nonrewarded trials followed by six rewarded trials every day for 12 days; and, in the other treatment, subjects received six rewarded trials followed by six nonrewarded trials every day for 12 days. These successive acquisition and extinction (SAE) treatments were selected because different extinction rates on the nonrewarded trials are expected on the bases of previous research performed with rats. Analyses of variance revealed the former treatment yielded significantly greater resistance to extinction than did the latter treatment. It was concluded that ducklings performed similarly to rats in the above SAE situation.  相似文献

This paper presents two new techniques for use in personnel selection. One is a simple graphical technique which non-technical personnel can use to help in deciding how many minority applicants to admit to an institution. The other is a large-scale computer technique which an institution can use to increase personnel diversity on many variables (including culture) simultaneously. Both techniques appear to have major advantages over the particular technique this author advocated previously (1971). However, the new techniques are based on the same general view the author has expressed earlier (1971, 1973): that personnel selection questions concerning culture must be handled rationally—that is, by human judgment—rather than by mechanical formulas. Early sections of the paper summarize and defend that view.  相似文献

An experiment designed to train engineering students to two levels of terminal achievement within single institutions is reported. The operative engineers (formerly high level technicians) qualify after three years whilst research and development engineers (fully qualified engineers) take five years. Organisational and curricular problems necessarily created by such integrated schemes are described and discussed. Social attitudes in society in general and in the student body in particular make the task of directing students towards the shorter form of training complex and difficult. From the experience gained so far it can confidently be asserted that the experiments in two-level training have been successful.Note by the Editor: This article is an abbreviated version prepared by the Editor of a 90-page UNESCO (copyright) report with the same title, Document ED. 75/WS/64, dated October 1975. We are grateful to the authors and to UNESCO for permission to print this summary of the report.  相似文献
