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.

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
