Philip Barnett 《The Reference Librarian》2014,55(2):118-127
This article addresses what reference librarians should do when patrons ask for information about explosives or dangerous drugs, and explores how reference librarians can possibly deter people from dangerous, unmediated searches by proactively providing information and actual examples on the dangers and risks of making and using these materials. 相似文献

Are students’ mathematical procedures as unstable as they seem? Students often produce different errors in response to the same kind of problems on different testing occasions. This finding is puzzling. Past research has shown that students induce overly general procedures from worked-out examples during learning, which lead to a host of predictable errors on new problems. Do students create rule-based errors only to then switch between them at random? In this paper, we show that seemingly diverse errors on two different testing episodes may result from the same underlying stable procedure and are part of the same error category. These findings suggest that students’ errors are more stable on a category vs. on an individual level. The current study consists of teaching students addition in a new number system, called NewRoman, and analyzing students’ solution strategies in detail. Implications for teaching are discussed. 相似文献

This paper examines two theoretical perspectives from which the issue of individual differences in memory can be viewed and relates the perspectives to evidence available in the literature. The paper also reports the results of two studies which bear upon the issue of whether there are individual differences in the retention of learned material. The last section of the paper examines the educational implications of one of the theories presented in the paper. 相似文献
