A norm distribution consisting of test scores received by 810 college students on a 150 item dichotomously-scored 4-alternative multiple-choice test was empirically estimated through several item-examinee sampling procedures. The post mortum item-sampling investigation was specifically designed to manipulate systematically the variables of number of subtests, number of items per subtest, and number of examinees responding to each subtest. Defining one observation as the score received by one examinee on one item, the results suggest that as the number of observations increases beyond 1.23% of the data base all procedures produce stochastically equivalent results. The results of this investigation indicate that, in estimating a norm distribution by item-sampling, the variable of importance is not the item-sampling procedure per se but is instead the number of observations obtained by the procedure. It should be noted, however, that in this investigation the test score norm distribution was approximately symmetrical and the possibility should not be overlooked that item-sampling as a procedure may be robust only for symmetrical norm distributions. 相似文献

File format obsolescence is a major risk factor threatening the sustainability of and access to digital information.While the preservation community has become increasingly interested in tools for migration and transformation of file formats,the National Library of Australia is developing mechanisms specifically focused on monitoring and assessing the risks of file format obsolescence.This paper reports on the AONS Ⅱ prpkect,undertaken by the National Library of Australia(NLA)in conjunction with the Australian Partnership for Sustainable Repositories(APSR).The project aimed to develop a software tool which allows users to automatically monitor the status of file formats in their repositories,make risk assessments based on a core set of obsolescence risk questions,and receive notifications when file format risks change or other related events occur.This paper calls for the preservation community to develop a co-operating file format obsolescence community which includes registries,software tool creators and end users to effectively curate digital content in order to maintain long-term access. 相似文献

Two hundred and fifty Neighborhood Youth Corps participants experienced group counseling over a 10-week period. Approximately half of the groups were conducted by five counselors who were supervised by a practicum instructor, and the remainder of the groups were led by unsupervised counselors. The participants in the supervised counseling groups were more positive toward their experiences than were those in the unsupervised counseling groups. The need for continuing supervisions or consultation of counselors is emphasized. 相似文献

In comparing the intergenerational relationships of counselor trainees and a nonclinical sample, counselor trainees reported healthier relationships with their parents and spouses concerning intergenerational triangulation, intergenerational intimidation, and spousal fusion and less healthy relationships with spouses and children on nuclear family triangulation. 相似文献

Gender differences in mathematics learning in the high school serve as a basis for achievement in mathematical disciplines in higher education, as well as in social mobility in Western society. The main findings reported here are that, in the Jewish sector in Israel, even when the level of mathematics is held constant, so that the perceived degree of achievement in mathematics of boys and girls is similar, girls are nevertheless found to report a lower degree of self-confidence in mathematics than boys on a number of different measures. Paradoxically, the educational system in the Arab sector, despite its gender conservatism relative to the general Jewish sector, has succeeded in generating amongst its female students a high degree of perceived achievement and self-confidence in mathematics, which in turn increases their willingness to consider mathematically-based studies and professions in the future. 相似文献

The paper seeks to unpick and examine a number of related claims for the role of the arts or, more specifically, the creative arts, in educational research. It considers and evaluates ways in which artistic creativity might itself be thought of as either based on research or itself a form of inquiry which might claim to be research. Such claims are entirely plausible, though they perhaps force artistic creativity into a particular mould that not all artists would appreciate. Artistic work may also constitute data conveying information about a particular setting or the events from which they were produced, signs and symbols for the observer or researcher to interpret. The claim that art might be used to represent educational practice, policy or experience receives the fullest treatment, and this requires consideration of both the general claim (which runs counter to the ambitions of many artists, choreographers and musicians) and more particular claims for, for example research-based narrative fiction, which is treated somewhat sceptically. 相似文献

This article describes a study of The Power of Maps, an exhibition presented in 1992 at the Cooper-Hewitt, National Design Museum, in New York City. The study compared the result of surveys administered to visitors at the Cooper-Hewitt as they entered and exited the exhibition with a control group of surveys administered to visitors at the National Portrait Gallery in Washington, DC, who had not seen The Power of Maps exhibition. It was found that visitors who were surveyed as they entered the exhibition were closer in agreement with the message of the exhibition than the control group. It was also found that visitors surveyed upon exiting The Power of Maps exhibition were in closer agreement with the message of the exhibition than with visitors who were surveyed as they entered the exhibition. The study demonstrates that it is possible to document a change in visitors' conceptions about a topic as a result of hearing about or visiting an exhibition and reliably determine the degree to which exhibitions can influence visitors. 相似文献
