This article presents a reciprocal model of mentoring as an alternative approach to more traditional mentoring models. A mentor, experienced with online course delivery and pedagogy, worked with six online instructors over two academic terms within a reciprocal mentorship model. This model was designed to build a collaborative learning relationship which would benefit each partner. The mentoring was scheduled on a just‐in‐time basis in response to each online instructor’s needs. Study results show that the time commitments required to accomplish the goals of the mentoring project were challenging for participants; that post‐secondary institutions have a responsibility to provide multiple supports (including, for example, mentoring assistance) for faculty members teaching online; and that developing a structured mentoring program could facilitate a more effective reciprocal mentoring process, with benefits for both mentors and mentees.  相似文献

In order to improve learning efficiency and memory retention in medical teaching, furthering active learning seems to be an effective alternative to classical teaching. One option to make active exploration of the subject matter possible is the use of virtual reality (VR) technology. The authors developed an immersive anatomy atlas which allows users to explore human anatomical structures interactively through virtual dissection. Thirty-two senior-class students from two German high schools with no prior formal medical training were separated into two groups and tasked with answering an anatomical questionnaire. One group used traditional anatomical textbooks and the other used the immersive virtual reality atlas. The time needed to answer the questions was measured. Several weeks later, the participants answered a similar questionnaire with different anatomical questions in order to test memory retention. The VR group took significantly less time to answer the questionnaire, and participants from the VR group had significantly better results over both tests. Based on the results of this study, VR learning seems to be more efficient and to have better long-term effects for the study of anatomy. The reason for that could lie in the VR environment's high immersion, and the possibility to freely and interactively explore a realistic representation of human anatomy. Immersive VR technology offers many possibilities for medical teaching and training, especially as a support for cadaver dissection courses.  相似文献

In the last decades, many similarity measures are proposed, such as Jaccard coefficient, cosine similarity, BM25, language model, etc. Despite the effectiveness of the existing similarity measures, we observe that none of them can consistently outperform the others in most typical situations. Choosing which similarity predicate to use is usually treated as an empirical question by evaluating a particular task with a number of different similarity predicates, which is not computationally efficient and the obtained results are not portable. In this paper, we propose a novel approach to combine different similarity predicates together to form a committee so that we do not need to worry about choosing which of them to use. Empirically, we can obtain a better result than any individual similarity predicate, which is quite meaningful in practice. Specifically, our method models the problem of committee generation as a 0–1 integer programming problem based on the confidence of similarity predicates and the reliability of attributes. We demonstrate the effectiveness of our model by applying it on three datasets with controlled errors. Experimental results demonstrate that our similarity predicate committee is more robust and superior over existing individual similarity predicates.  相似文献

Objective:

This research measures the effectiveness of the practice of correction and republication of invalidated articles in the biomedical literature by analyzing the rate of citation of the flawed and corrected versions of scholarly articles over time. If the practice of correction and republication is effective, then the incidence of citation of flawed versions should diminish over time and increased incidence of citation of the republication should be observed.

Methods:

This is a bibliometric study using citation analysis and statistical analysis of pairs of flawed and corrected articles in MEDLINE and Web of Science.

Results:

The difference between citation levels of flawed originals and corrected republications does not approach statistical significance until eight to twelve years post-republication. Results showed substantial variability among bibliographic sources in their provision of authoritative bibliographic information.

Conclusions:

Correction and republication is a marginally effective biblioremediative practice. The data suggest that inappropriate citation behavior may be partly attributable to author ignorance.

Highlights

  • The citation of flawed articles occurs at a rate nearly equal to that of corrected versions.
  • The practice of correction and republication is only marginally effective and does not prevent the continued citation of flawed articles post-correction, with the analysis finding only a slight reduction in the citation of flawed articles after publication of the corrected version.
  • Neither MEDLINE nor Web of Science consistently alert users when dealing with corrected and republished literature.

Implications

  • The practice of correction and republication would be more effective if prominent sources of bibliographic information were more consistent in providing users with information about the status of corrected and republished articles and the existence of post-publication modifications to the literature.
  • It is incumbent upon the scientific community to raise the profile of post-publication changes to the literature to prevent the wasteful and potentially tragic consequences of scientists and medical professionals applying flawed information. Failure to do so will surely result in a reduction of public trust in the reliability of the scientific literature and its users.

This article examines differences in the mathematics and English proficiency of academic-track students in Baden-Württemberg (N?=?3526) and Hamburg (N?=?3734), investigating whether and to what extent these differences are reflected in the Abitur grades the students are awarded. The article also examines the extent to which scores in centrally conducted examinations provide better comparability than do coursework grades. Multilevel analyses predicting coursework grades in mathematics revealed clear between-state differences, with students in Hamburg being awarded higher mathematics grades than comparably able students in Baden-Württemberg. These differences are partly attributable to frame of reference effects and their impact on teachers’ grading practices. No corresponding between-state differences were found for English. Mathematics examination scores provided a much better measure of student achievement than mathematics coursework grades. The findings are discussed in terms of meritocratic access to sought-after university and training places.  相似文献

Classroom research on achievement goals has revealed that performance-approach goals (goals to outperform others) positively predict exam performance whereas performance-avoidance goals (goals not to perform more poorly than others) negatively predict it. Because prior classroom research has primarily utilized multiple-choice exam performance, the first aim of the present study was to extend these findings to a different measure of exam performance (oral examination). The second aim of this research was to test the mediating role of perceived difficulty. Participants were 49 4th year psychology students of the University of Geneva. Participants answered a questionnaire assessing their level of performance-approach and performance-avoidance goal endorsement in one of their classes as well as the perceived difficulty of this class for themselves. Results indicated that performance-approach goals significantly and positively predicted exam grades. Performance-avoidance goals significantly and negatively predicted grades. Both of these relationships were mediated by the perceived difficulty of the class for oneself. Thus, the links previously observed between performance goals and exam performance were replicated on an oral exam. Perceived difficulty is discussed as a key dimension responsible for these findings.  相似文献

An experimental study investigated the influence of informational dependence on information appropriation as a function of epistemic authority’s styles. In a 2×2 design, university students were informed that acknowledging epistemic dependence was related either to academic success or to academic failure, and were exposed to controversial information from an epistemic authority that used either an authoritarian or a democratic style. The main dependent variable was the extent to which participants appropriated the controversial information. Firstly the results showed that students were more inclined to admit that their own academic competence depended on the information delivered by the teachers when epistemic dependence was related to success rather than to failure. Secondly, the admittance of dependence had a different impact on information appropriation according to the authority’s style. Admittance increased appropriation under a democratic style whereas it decreased appropriation under an authoritarian style.  相似文献

Do the listening styles preferred by young adults in Germany,Israel, and the USA differ significantly? In order to addressthis question, college students in all three countries completedversions of the Listening Styles Profile (LSP; Watson et al.1995) presented in their native languages. Factor analysis revealedfour predominant constructs underlying the LSP, which were designatedas people, action, content, and time listening styles. Comparisonsbetween the three cultures revealed distinctively differentpatterns of listening style preferences, with Germans preferringthe action style, Israelis endorsing the content style, andAmericans favoring both the people and time styles.  相似文献

The use of emotions in political campaigns is known and welldocumented. From its earliest days in the Roman Empire or laterin Crusader times to its extensive use by the Nazi regime, politicalpropaganda attempted to seduce and convince, attract and influencetargeted publics by appealing to their emotions. Appeals tofear, hope, pride, anger, and anxiety are frequent in moderncampaigns too. Yet no attempts appear to have been made to developa methodological tool for the objective and systematic identificationof the use of such appeals. This research is based on the design,testing, and validation of a research instrument intended tomeasure quantitatively and comparatively the use of emotionalappeals in two Israeli election campaigns (1996 and 1999). Italso reports findings from an application of the new measureto test specific hypotheses on the use of emotional appealsacross campaigns and parties.  相似文献
