In an experiment with 65 high-school students, we tested the hypothesis that personalizing learning materials would increase students’ learning performance and motivation to study the learning materials. Students studied either a 915-word standard text on the anatomy and functionality of the human eye or a personalized version of the same text in which 60 definite articles (e.g., “the eye”) were replaced with 60 second-person possessive pronouns (e.g., “your eye”). Afterwards, participants answered comprehension and transfer questions. One week later, the participants were asked to restudy the text and to answer the same questions again with the aim to improve their performance. In the personalized text condition, students showed higher transfer performance, spent more time on restudying the text, and reported being more motivated than students in the standard text condition. However, only duration of restudying (not self-reported motivation) mediated the effect of personalization on transfer performance.  相似文献

Ethical literacy seems to be used, within Education for Sustainable Development (ESD), in various ways, some more general and others morally specific, emphasising individuals’ responsibility. The overarching aim of this paper is to present some prerequisites for the development of narrative methods that focus on the vision of a good society without compromising individual integrity. Is it possible to develop ESD in a ways that highlight global challenges with a focus on justice and equity without either, as within post-political romanticism, pretending that social sustainability is a non-controversial ethical goal, or, as within liberal individualistic approaches, claiming that no one may escape from the demands of action competence, which, it is claimed, paves the way for making social sustainability a reality? With reference to some threads in narrative theory and by an analysis of six children’s books, this paper critically and constructively examines storytelling as one method to inspire young people to reflect upon what a good society and a good world might be, to catch sight of visions of a sustainable world and of the differences between how things are and how things could be – a method that may also preserve respect for individuals’ integrity.  相似文献

ABSTRACT

Since the mid-1980s, the working lives of teachers has become an enduring research topic. Much research has focused on early-career teachers and is often reported from deficit positions, i.e. why they leave the profession. However, career trajectory studies have described a small cohort of veteran teachers who remain positive and committed to teaching. This article reports on the creation and piloting of an instrument designed to test whether this positive cohort can be empirically identified within a wider teaching population. Four constructs (experimentation, challenge, comfort and leadership) drawn from Huberman (1993), and Day and Gu (2007) formed the basis for an online pilot survey completed by 145 teachers. Exploratory and confirmatory factor analysis supported three of the four factors (experimentation, comfort, leadership), with challenge loading strongly with experimentation. Initial findings suggest the potential of the instrument in helping identifying positive veteran teachers within systems, as well as the voracity of the research approach. Examining and articulating how these veteran teachers maintain their positive outlook may prove valuable as many countries confront an ageing teaching workforce, increasing student numbers and difficulties in retaining experienced teachers, meaning those who remain will be expected to sustain their commitment for longer.  相似文献

The purpose of the study was to use multivariate multilevel techniques to investigate whether it was possible to separate different dimensions in grades that relate to subject-matter achievement and to other factors. Data were derived from The Gothenburg Educational Longitudinal Database (GOLD), and the subjects were 99,070 ninth-grade students born in 1987. The analyses were based on subject grades and scores on national tests in Swedish, English, and mathematics. The results showed that, at both individual and school levels, the greatest part of the variance in grades was due to achievement in the different subject areas. At both levels, it was possible to identify a dimension that cut across the grades in all 3 subjects, which suggests that grading is influenced by factors other than achievement. One of the most interesting results concerns the relation between parental education and the common grade dimension at the school level.  相似文献

The purpose of the study is to investigate the predictive validity of criterion- and norm-referenced grades and the Swedish Scholastic Aptitude Test (SweSAT) and, in particular, possible differences in the prediction of achievement in higher education across academic programs. The analyses were based on credit points obtained by 164,106 Swedish students during the years 1993 to 2001. Two-level modeling with randomly varying slopes with academic program as cluster variable was used. The results provide means and variances of the slopes across the different programs. Variability in the slopes because of program subject area was also investigated. The results indicate that the validity of grades, irrespective of grading system, is stronger in comparison with SweSAT scores. The results also indicate considerable differences in predictive power across programs for the SweSAT, whereas there are much smaller differences for norm-referenced grades and relatively modest differences for criterion-referenced grades. The impact of program subject area on the variability of prediction was substantial for SweSAT scores.  相似文献

In recent years studies have shown that sport can serve as a means towards conflict resolution. Since the time of British colonialism in the 1950s, and after its 1960 independence, Cyprus has experienced conflict between its two main communities – the Greek Cypriots and the Turkish Cypriots. The de facto division of the island in 1974 caused community isolation of the Turkish Cypriots who, for political reasons, have been excluded from participating in international sports competitions. This situation is more visible in football (soccer), the most popular sport on the island. In the last two years the two sides have been trying – so far unsuccessfully – to reinstate the Turkish Cypriots as members of the Official Cyprus Football Federation. This paper gives a background on what has preceded these attempts and discusses whether football is a means of reuniting the two communities, or whether it is used as a vehicle to further separation.  相似文献

A universal coagulation test that reliably detects prolonged coagulation time in patients, irrespective of the anticoagulant administered, has not been available to date. An easily miniaturised, novel μ-fluidic universal coagulation test employing surface acoustic waves (SAW) is presented here. SAW was employed to instantly mix and recalcify 6 μl citrated whole blood and image correlation analysis was used to quantify clot formation kinetics. The detection of clinically relevant anticoagulant dosing with old anticoagulants (unfractionated heparin, argatroban) and new anticoagulants (dabigatran, rivaroxaban) has been tested and compared to standard plasma coagulation assays. The applicability of this novel method has been confirmed in a small patient population. Coagulation was dose-proportionally prolonged with heparin, argatroban, dabigatran, and rivaroxaban, comparable to standard tests. Aspirin and clopidogrel did not interfere with the SAW-induced clotting time (SAW-CT), whereas the strong GPIIb/IIIa-inhibitor abciximab did interfere. Preliminary clinical data prove the suitability of the SAW-CT in patients being treated with warfarin, rivaroxaban, or dabigatran. The system principally allows assessment of whole blood coagulation in humans in a point-of-care setting. This method could be used in stroke units, emergency vehicles, general and intensive care wards, as well as for laboratory and home testing of coagulation.  相似文献

The functional classification system for wheelchair basketball is based on an analysis of the players' functional resources through field-testing and game observation. Under this system, players are assigned a score of 1 to 4.5. The aim of this study was to determine if the wheelchair basketball player classification system reflects the existing differences in performance of elite female players. During the World Championship for Wheelchair Basketball in Sydney 1998, eight teams were videotaped for three 40-min games for a total of 120?min per team. Fifty-nine female players (Class I [1 and 1.5 points] n?=?12; Class II [2 and 2.5 points] n?=?20; Class III [3 and 3.5 points] n?=?13; Class IV [4 and 4.5 points] n?=?14) were retained for a detailed performance analysis by means of the Comprehensive Basketball Grading System (CBGS). Two-way analysis of variance showed high point players to perform better compared with low point players for the majority of variables determining the quality of game performance. A lack of significant differences between two adjacent classes was explained on the basis of the methodological approach, the class–position relationship in this sample, and the performance level of women's wheelchair basketball. We conclude that the performance of elite female wheelchair basketball players is dependent on functional ability.  相似文献

Abstract

This study investigated the time needed to change a motor program that specified the elbow flexor muscles to gradually increase the isometric force production from 15% to 75% of one's maximum voluntary contraction (MVC). A double-stimulation paradigm was used with the restriction that subjects (N = 12) be at 15% of their MVC before the presentation of the first stimulus. Subjects reacted to the first stimulus (randomly presented) by gradually increasing their isometric force from 15% to 75% of their MVC and then reacted to the second stimulus by altering the force production in one of four ways: (a) increasing the force to the 75% level rapidly instead of gradually, (b) discontinuing the increase and maintaining the level of force attained, (c) discontinuing all force production, or (d) reversing the direction of force so that it is produced by the elbow extensors. The data revealed that more time was needed to increase the force rapidly than to perform any of the other three conditions.  相似文献

Sport and physical activity are attributed with a positive influence on stress induced complaints due to their overall positive effect on health. The buffering effect on stress has not yet been clearly shown and the findings are inhomogeneous. The following article examines the buffering effect of sport and physical activity on different types of psychological and physical complaints. Therefore, a study was conducted questioning 453 people (M?=?53.56 years; SD?=?11.31) about chronic stress (Perceived Stress Scale), physical complaints (Gießener Beschwerdebogen) and their subjective physical activities (Energy consumption through physical activity – e.g. Soccer or Jogging) and energy consumption – daily bike and walking activity). A buffering effect on nearly all types of complaints could be shown through physical activity, but not through lifestyle activities. Physical activity acts complaint reducing on people suffering from increased stress. A more differentiated examination of the physical activity behaviour, the stress perception and the type of complaints might contribute to clearer findings.  相似文献
