Heiko Spallek  Peter Berthold  Diarmuid B. Shanley  Rolf Attstrom 《The American journal of distance education》2013,27(2):49-59

Abstract

This study describes the development and the evaluation of quality assurance criteria for online dental education. These criteria were developed by the authors and evaluated by oral health professionals through an Internet survey. The survey indicated that oral health professionals ranked the creation of scientifically based, frequently updated courses that clearly define their educational goals and objectives as highly important.  相似文献   

Introducing quantum mechanics in the upper secondary school: A study in Norway     

Rolf V. Olsen 《International Journal of Science Education》2013,35(6):565-574

The study reported in this paper is a survey (n=236) that examines how upper secondary students (18-19 years old) in Norway come to terms with the wave-particle duality as presented as part of a short introduction to quantum physics. The main conclusion is that this concept is poorly understood. Some students demonstrate clear and explicitly formulated misconceptions rooted in a classical physics world-view. Scholars in physics have stated that the concept of duality is unnecessary, but still included in school and university physics. It is argued that school physics should give a more explicit focus to the challenge that quantum physics presents to the classical worldview, thus introducing the importance of an affective dimension in the learning and teaching of quantum physics. This study replicates evidence from other studies that wave-particle duality does not introduce such a challenge.  相似文献   

Literature Awareness Among Health Staff in Developing Countries     

Rolf Weitzel 《International Information and Library Review》2013,45(3):203-212

Abstract

Health professionals, although in principle a highly information-conscious group, are frequently observed to be poor users of literature and library services. The main reason for this lack of literature awareness is the tradition of oral transmission of knowledge found in a number of Third World countries. Since the practice of modern medicine is not conceivable without constant support from the professional literature, either for reference or continuing education purposes, it is suggested that national or regional programmes be launched to promote literature awareness, notably among medical and nursing students. This requires the active participation of faculty staff as well as policy and financial commitments of the governments concerned. Failure to heighten the literature awareness of coming generations of physicians and nurses, and in general to improve the situation in the sector of health information support could have serious consequences on the quality of medical care in large parts of the developing world.  相似文献   

High-speed observations of football-boot-surface interactions of players in their natural environment

A protocol has been developed to obtain two-dimensional kinematic shoe data of football players in their training environment through high-speed video analysis. Such kinematic data can provide an understanding of how to better replicate the boundary conditions of football movements when simulated using mechanical traction and penetration test devices. As part of a pilot study, 11 youth academy players from a Premiership football club performed football-specific movements which were filmed at 1000 frames s^-1. The protocol required minimal set-up time and the area of the pitch to be filmed could be positioned in any part of the playing area, causing low disruption to the players. This aimed to ensure that the movements performed were representative of those carried out during competitive play. Results in this study are concerned with the kinematics of the shoe during contact with the ground for movements identified to be important in terms of injury risk and loss of performance (slipping). Shoe velocities and orientations were measured for subjects wearing shoes of different stud types (traditional round studs versus contemporary bladed studs) on two surfaces (artificial turf, in-filled with rubber and sand, versus a natural surface). All the parameters measured from the relatively small population of subjects had high variances and therefore few significant effects of studs and surface could be found. The data does however provide insight into the appropriate boundary conditions to be used in mechanical test devices. For example, in the forefoot push-off movement it can be seen that test devices should measure the traction forces when the shoe first starts to move, as this is when the player would lose performance, as opposed to the maximum traction which can occur after significant displacement of the shoe through the surface. Analysis of the orientation and velocity path of the studs just before contact with the ground shows that the studs could be aligned to enhance their penetration into the surface and optimise the traction properties of the studs. In order to determine the orientation and velocity of the shoes at crucial phases in movements force-plate data obtained in the laboratory should be utilised in future studies.  相似文献

What contributes to the split-attention effect? The role of text segmentation,picture labelling,and spatial proximity     

Mareike Florax  Rolf Ploetzner 《Learning and Instruction》2010,20(3):216-224

In the split-attention effect spatial proximity is frequently considered to be pivotal. The transition from a spatially separated to a spatially integrated format not only involves changes in spatial proximity, but commonly necessitates text segmentation and picture labelling as well. In an experimental study, we investigated the influence of spatial proximity, text segmentation, and picture labelling on learning performance. A total of 165 students, divided into five groups, participated in the study. Four of the groups learned from spatially separated texts and pictures in a 2 × 2 design with the factors text segmentation (continuous vs. segmented text) and picture labelling (unlabelled vs. labelled picture). The fifth group learned from a spatially integrated text and picture. Retention and comprehension of the learning material were assessed. Students' working memory capacity and spatial ability were also assessed. The results replicated the split-attention effect with respect to retention only. This effect is attributed mainly to text segmentation and only partially to picture labelling. Spatial integration, however, did not enhance learning.  相似文献

The Contribution of International Large-Scale Assessments to Educational Research: Combining Individual and Institutional Data Sources     

Rolf Strietholt  Ronny Scherer 《Scandinavian Journal of Educational Research》2018,62(3):368-385

The present paper aims to discuss how data from international large-scale assessments (ILSAs) can be utilized and combined, even with other existing data sources, in order to monitor educational outcomes and study the effectiveness of educational systems. We consider different purposes of linking data, namely, extending outcomes measures, analyzing differences over time or across cohorts, and supplementing context information. These linking strategies are illustrated by a non-exhaustive selection of studies that exploited ILSAs to investigate a wide range of educational topics. We conclude that the main contribution of ILSA to educational research lies in the ways they facilitate analyses of educational policy and policy-related issues at the institutional level by means of cross-country analyses. However, the scope of these studies also covers high-quality data on lower levels of the educational system.  相似文献   

Practical Experience in Teacher Education: the Norwegian case from a mid‐Norwegian perspective     

Rolf Grankvist 《欧洲师范教育杂志》1996,19(3):337-346

After numerous debates and discussions over the last century Norway decided in 1992 to extend the half year GCE‐course at the universities to a one year study. Due to this decision it was for the first time written National Guidelines for these kinds of studies.

This paper seeks to show how this change is carried out at one of the four universities in Norway—the Norwegian University of Science and Technology in Trondheim. The author presents this reform under the heading practical experience in Teacher Education. This is done because the National Guidelines for Norway underline that all theory in the GCE‐studies must be school‐based. Practical classroom experience is, in other words, supposed to be the starting point for all theory being taught as a part of the GCE‐program.

This paper also tries to view the Norwegian change in the GCE‐course from international trends within teacher education.  相似文献
