Scientific journals are the primary mode of formal communication in science. The ISI Impact factor, a bibliometric indicator that measures the citation rate of the “average” article in a journal, has been widely used for the assessment of the quality of scientific production of individuals, research teams or institutions. The purpose of this paper was to present the impact factor, examine the main limitations in its calculation and applications and to give a general overview of the impact factor of education journals for the period 2000–2005. Several problems related to the calculation of the impact factor have raised serious concerns about its validity and usefulness. Our findings suggest that education journals included in the Journal Citation Reports (JCR) represent about 11% of the active, referred, academic journals. Education journals have relative low impact factors, in absolute values and in comparison to other Social Science categories. Application of the intraclass correlation coefficient showed that journals belonging to the “Education and Educational Research” category had relative stable impact factor values for the examined 6 years. This was not the case for the journals from the “Education, Special” category. It was concluded that the use of impact factor for the evaluation of journals, articles and researchers should be done with considerable care. 相似文献

The aim of this study was to develop an instrument for evaluating how an education program has been implemented. Such evaluation
can provide insight into the effectiveness of a program. Examined here was the Olympic Education Program used in Greek schools
since 2000. In it, students learn the history of the Olympic games and the importance of exercise for health along with the
principles and values of sports and volunteerism. The evaluation instrument underlying this study addressed the following
six factors: ‘facilities’, ‘administration’, ‘educational material’, ‘student–teacher relationships’, ‘educational procedures’,
and ‘training’. Results indicate that the instrument, while adequate for assessing effectiveness, should be combined with
advanced statistical methods. 相似文献

The rigours of the past few years have demonstrated the importance of good health literacy levels with the imperative of being able to obtain and interpret information to maintain and improve one's health never more apparent. With this in mind, this issue is focused on consumer health information, the gender and population group differences that exist in information seeking behaviour, the challenges of understanding medical explanations and terminology, and existing criteria to assess and ultimately produce better consumer health information. 相似文献

A hybrid two-stage flowshop scheduling problem was considered which involves m identical parallel machines at Stage 1 and a burn-in processor M at Stage 2, and the makespan was taken as the minimization objective. This scheduling problem is NP-hard in general. We divide it into eight subcases. Except for the following two subcases: (1) b≥ an, max{m, B} 〈 n; (2) a1 ≤ b ≤ an, m ≤ B 〈 n, for all other subcases, their NP-hardness was proved or pointed out, corresponding approximation algorithms were conducted and their worst-case performances were estimated. In all these approximation algorithms, the Multifit and PTAS algorithms were respectively used, as the jobs were scheduled in m identical parallel machines. 相似文献

The main purpose of this study was to investigate the effects of active learning on preservice teachers' dignity, energy, self-management, community, and awareness (DESCA) abilities, attitudes toward teaching, and attitudes toward science. Third year preservice teachers (n = 77) from two different classes were involved in the study. One intact class was assigned as the experimental group, whereas the other intact class was assigned as the comparison group. The comparison group students received the instruction by traditional teaching, and the experimental group received instruction through an active learning paradigm. DESCA abilities and attitudes were measured before and after instruction. Results revealed that there was a significant difference favoring the active learning instruction on preservice teachers' DESCA scores; however, there was no significant difference on preservice teachers' attitudes toward teaching and science. 相似文献

Studies show that recent generations of college students have a learning style with identifiable characteristics. Library instruction efforts must adapt to these learning styles. Course management software (CMS), such as Blackboard, is one resource available to academic librarians to meet the challenges posed by the "Net Generation." At Stetson University, the use of Blackboard courseware in library instruction sessions successfully addressed the unique learning styles of students. 相似文献

Performance support systems are mechanisms enabling users) productivity while reducing training expenses as support is being delivered in real time, often eliminating the need for costly pre‐performance training. Mobile technologies have created new opportunities for improved performance support systems, especially for tasks performed outside the offi ce. This article describes the fi rst mobile learning and performance support initiative taken by the Israeli Air Force. The project included the development and eff ectiveness pilot study of a learning and performance support application delivered via tablet to helicopter engine technicians. The application provided support videos and illustrations of maintenance routines, thereby enabling learning and practicing at the same time. Pilot study results show high performance levels of application users compared to those applying traditional methods. Results also show that self‐effi cacy levels were not aff ected by the successful performance achieved when using the mobile performance support application. Plans to expand mobile support use are also described. 相似文献
