Fifty-nine children in kindergarten, first, and second grade were given the WISC information and arithmetic subtest. Approximately three weeks later, the subjects were presented with the same questions, and four multiple choice answers were shown and read to them. The number of correct responses on each subtest for each presentation method was recorded. The multiple choice method of presentation response yielded significantly higher scaled scores than did the standard WISC presentation with the free response mode of testing. 相似文献

The book market in European countries is different than the U.S. market for various political, geographical, and cultural reasons. The authors outline these differences and provide background on the move to electronic commerce and future. The article includes many electronic and print sources of and bibliographic tools for locating books in the European market. 相似文献

The widespread use of handheld computers and other mobile devices in the healthcare environment and their potential for providing access to information has prompted health sciences librarians everywhere to learn more about this technology. Early in 2001, the Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill began exploring ways to support mobile computing. This paper describes the four basic approaches taken by the librarians that helped establish the HSL as a leader in the area of mobile technologies. 相似文献

Previous research has indicated that the keyword method of vocabulary learning facilitates students' performance not just on simple tests of definition recall, but on comprehension-demanding tasks as well. The present study was conducted to determine whether the “comprehension” finding could be accounted for by keyword subjects' superior definition recall per se. The results generally supported that conclusion: When conditions and subjects within conditions were equated with respect to their initial levels of definition recall, the comprehension advantage of keyword subjects disappeared. 相似文献

Tudor-Locke and colleagues previously assessed steps/day for 1 year. The aim of this study was to use this data set to introduce a novel approach for the investigation of whether individual’s physical activity exhibits periodicity fluctuating round a mean and, if so, the degree of fluctuation and whether the mean changes over time. Twenty-three participants wore a pedometer for 365 days, recorded steps/day and whether the day was a workday. Fourier transform of each participant’s daily steps data showed the physical activity had a periodicity of 7 days in half of the participants, matching the periodicity of the workday pattern. Activity level remained stable in half of the participants, decreased in ten participants and increased in two. In conclusion, the 7-day periodicity of activity in half of the participants and correspondence with the workday pattern suggest a social or environmental influence. The novel analytical approach introduced herein allows the determination of the periodicity of activity, the degree of variability in activity that is tolerated during day-to-day life and whether the activity level is stable. Results from the use of these methodologies in larger data sets may enable a more focused approach to the design of interventions that aim to increase activity. 相似文献
