This paper reports two studies of standard setting using Angoff's method. Results of the first study suggest that specialization within broad content areas does not affect an expert's estimates of the performance of the borderline group. This is reassuring because the knowledge base of many professions is so large that no individual can be considered an expert in all aspects of it. Results of the second study support the recommendation that performance data be provided during the standard-setting process. They are frequently used by experts, but will not have an impact on the standard unless the distribution of item difficulties is skewed markedly. It also increases the correspondence between p-values and estimates of borderline group performance, thereby reducing errors in pass/fail decisions. Overall, the results support recommendations often made in standard-setting literature, but they need to be replicated with other groups of experts  相似文献

Ten Cameroonian women were interviewed in order to find out how they had managed to become scientists and science educators. We talked to them about the kinds of support they had been given by their families, how science was taught in schools both in the past and at present, and whether or not they thought it possible to integrated science and African traditional thought in schools and universities. We used a framework incorporating the concepts of gender and social class in order to interpret their views. On this basis, we understood why these women tended to underestimate the importance of institutional discrimination in science and to conceive of the norms of professionalism as unsurpassable. In contrast, we suggest that women in Cameroon will only be able to participate fully when their own experience and ways of knowing are incorporated into the teaching and structures of science.  相似文献

This article examines the hypothesis that there are preliminary stages in problem solving which most chemists neglect when trying to teach their students how to solve problems in introductory chemistry courses. It is during these early stages that relevant information is disembedded from the question and the problem is restructured. Unless students can successfully complete these cognitive restructuring stages, they cannot proceed on to the more analytic stages in problem solving that have received more attention from chemists. Preliminary evidence for this hypothesis consists of linear correlations between student ability to handle disembedding and cognitive restructuring tasks in the spatial domain and their ability to solve chemistry problems.  相似文献

Despite clear European and Dutch policies about media education, there is currently no media education curriculum in Dutch schools. A survey among preadolescents (n = 257) in six primary schools in the Netherlands included questions regarding media access, fears, risks, parental mediation of television and the internet, and the need for media education. Findings indicate an overall high saturation of media, but media choice depends on sociodemographic factors. Preadolescents are given rules for using the internet more often than for TV. Boys feel more confident about media use, and few participants report negative experiences or perceive risks while using the internet. Pupils feel a high need for media education, and those who are already thinking critically about media demand lessons more often. Therefore, both technical knowledge about media and critical awareness of the influence of media must be taught.  相似文献

The purpose of this study was to develop an abbreviated version of the Perceived Motivational Climate in Exercise Questionnaire (PMCEQ-A) to provide a more practical instrument for use in applied exercise settings. In the calibration step, two shortened versions’ measurement and latent model values were compared to each other and the original PMCEQ using a three-group CFA invariance testing approach with previously collected exercise setting data (= 5,427). Based on the model fit and reliability values, the 12-item version performed better than the 17-item version. The resultant 12-item PMCEQ-A’s CFA model estimates were then compared to the PMCEQ’s model values for two different, previously conducted studies of exercise settings (N = 414 and 770). The more parsimonious 12-item PMCEQ-A can be used by exercise psychology researchers to gain insight into members’ perspectives on the motivational climate and may lead to developing effective strategies to enhance members’ experiences and commitment.  相似文献

The paper explores boundaries of cross-boundary information sharing and integration in the context of Taiwan e-Government by using an integrated framework of boundaries adopted from the literature. The discussion of the various boundaries provides a thorough lens to understand the complexity of cross-boundary information sharing and integration. The adopted framework of boundaries is proved to be a useful analytical tool to perceive various vertical and horizontal boundaries in initiatives of cross-boundary information sharing and integration in different e-Government contexts. A new process boundary in the vertical dimension is also identified. In addition, the case shows that centralized information systems can help government agencies to cross the boundaries of information sharing and reduce the number of boundaries government agencies may encounter. Lastly, it is perceived that vertical boundaries are not always easier to cross than horizontal boundaries.  相似文献

Student dropout is a multi-causal process. Different theoretical models on student dropout consider dysfunctional study behavior (e.g., academic procrastination) and low study satisfaction as possible determinants of students’ dropout intentions during their university studies. However, these models neglect contemporary conceptualizations that assume reverse relationships between dropout intentions and other determinants of the dropout process. Until now, empirical evidence on these assumptions is scant. The present three-wave longitudinal study explored the reciprocal relationships between academic procrastination, study satisfaction, and dropout intentions over one semester. To this end, we used data of N = 326 undergraduate students enrolled in mathematics and law. Our latent cross-lagged panel model replicated existing empirical cross-sectional findings between the variables (i.e., academic procrastination, study satisfaction, and dropout intentions). Regarding the longitudinal relations, as expected, the cross-lagged effects showed that higher dropout intentions significantly related to subsequent higher academic procrastination and lower study satisfaction. Unexpectedly, academic procrastination did not significantly relate to subsequent dropout intentions. Additionally, higher study satisfaction significantly associated with subsequent higher dropout intentions—possibly due to unfulfilled expectations. Further, higher study satisfaction significantly related to subsequent higher procrastination—possibly due to more confidence among satisfied students. Our results broaden the view on dropout intentions as part of the dynamic interplay of student dropout determinants and the need to refine dropout models’ assumptions accordingly. Practically, realistic expectations seem important to reduce dropout intentions. Further, student counselors should have a closer look at the reasons for academic procrastination to develop individual solutions for this dysfunctional behavior.

This article presents an analysis of rich data, gathered from interviews with 46 candidates and 38 supervisors from three Australian universities, about experiences of doctoral supervision in cross-cultural situations. Our analysis shows that many of the issues reported by international candidates are the same as those encountered by domestic candidates. However, this study has identified eight intensifiers that make such situations more complicated or difficult for candidates in a cross-cultural context: language; cultural differences in dealing with hierarchy; separation from the familiar; separation from support; other cultural differences; stereotypes; time; and what happens when the candidate returns home. The two intensifiers mentioned by more than 50% of interviewees are separation from the familiar and language. Using intensifiers as a conceptual framework for self-examination may help universities to better understand the real issues, to target resources, to mitigate distress to international candidates and reduce pressure on supervisors.  相似文献
