Estimation of the direct effect of an exposure on an outcome requires adjustment for confounders of the exposure–outcome and mediator–outcome relationships. When some of the latter confounders have been affected by the exposure, then standard regression adjustment is prone to possibly severe bias. The use of inverse probability weighting under so-called marginal structural models has recently been suggested as a solution in the psychological literature. In this article, we show how progress can alternatively be made via G-estimation. We show that this estimation method can be easily embedded within the structural equation modeling framework and could in particular be used for estimating direct effects in the presence of latent variables. Moreover, by avoiding inverse probability weighting, it accommodates the typical problem of unstable weights in the alternative estimation approaches based on marginal structural models. We illustrate the approach both by simulations and by the analysis of a longitudinal study in individiduals who ended a romantic relationship. In this example we explore whether the effect of attachment anxiety during the relationship on mental distress 2 years after the breakup is mediated by rumination or not. 相似文献

Blended forms of learning have become increasingly popular. Learning activities within these environments are supported by a large variety of online and face-to-face interventions. However, it remains unclear whether these blended environments are successful, and if they are, what makes them successful. Studies suggest that blended learning challenges the self-regulatory abilities of learners, though the literature does little to explain these findings; nor does it provide solutions. In particular, little is known about the attributes that are essential to support learners and how they should guide course design. To identify such attributes and enable a more thoughtful redesign of blended learning environments, this systematic literature review (n?=?95) examines evidence published between 1985 and 2015 on attributes of blended learning environments that support self-regulation. The purpose of this review is therefore to identify and define the attributes of blended learning environments that support learners’ self-regulatory abilities. Seven key attributes were found (authenticity, personalization, learner-control, scaffolding, interaction, cues for reflection and cues for calibration). This review is the first to identify and define the attributes that support self-regulation in blended learning environments and thus to support the design of blended learning environments. This study may serve to facilitate the design of blended learning environments that meet learners’ self-regulatory needs. It also raises crucial questions about how blended learning relates to well-established learning theories and provides a basis for future research on self-regulation in blended learning environments. 相似文献

In this article, we focus on the links and synergies between the Ecole mondiale of King Leopold II of Belgium, the Plans du Collège Léopold II of Pierre du Coubertin and the establishment of the Belgian Olympic Committee in 1906. A firm belief in the advantages of international cooperation undercut these three projects that were planned in Belgium. Always accompanying the internationalist discourse was the conviction that they should also strengthen Belgium's international position. Consequently, they focused strongly on physical education and sport, emphasising the great expansionist assets. All in all, however, the outcomes of the projects were less than expected. While the Belgian Olympic Committee had a difficult start, Coubertin's project only existed on paper, and the Ecole mondiale never rose above its foundations because of serious practical and political issues. Nonetheless, the expansionist discourse did facilitate the creation of the Higher Institute of Physical Education at the State University of Ghent in 1908. 相似文献

This study examines whether peer feedback can be a substitute for teacher feedback and which measures can be taken to improve its effectiveness. A pre‐test post‐test control group design examined the long‐term learning effects of individual peer feedback and of collective teacher feedback on writing assignments in secondary education. Moreover, it examined the added value of a priori question forms and a posteriori reply forms aimed at supporting the assessee's response to peer feedback. The study supports the ‘non‐inferiority’ hypothesis of there being no significant difference in students’ progress after plain substitutional peer feedback or teacher feedback. Both groups (plain peer feedback and teacher feedback), however, improved significantly less than the groups that worked with question or reply forms, confirming the added‐value of these forms. Almost half of the students found the received peer feedback helpful, but less than a quarter considered giving feedback an aid in their own learning process. 相似文献

This study addresses the effects of negative attainability feedback on the shift from engagement to disengagement from a career goal. It was hypothesized that negative attainability feedback regarding study choice may lead to both goal engagement and goal disengagement and that this relation is mediated by self-efficacy, motivational beliefs, and by the perceived accuracy of feedback. Results confirmed that negative feedback led to goal disengagement and, to a lesser extent, to continued engagement. Perceived accuracy of feedback was an important mediator, as was motivation. Self-efficacy did not predict either goal management strategies. 相似文献

Teachers are supposed to use forms of differentiated instruction to anticipate the differences among their students. However, the adaptation of teaching to the diversity of the group often takes place with difficulty. Teacher education is blamed for not preparing student teachers adequately for differentiated instruction. Several authors suggest that congruent teaching in teacher education might be an adequate solution to this problem. This case study aims to investigate the (congruent) realization of differentiated instruction in teacher education using ethnographic tools. The results indicate that the observed teacher educator demonstrated limited forms of differentiation, largely without providing meta-commentary. Therefore, she is not a role model on the subject of differentiated instruction in the view of student teachers. These results are discussed in depth, and form a basis for further research and suggestions for practice in teacher education. 相似文献

Answering the legitimate call for a more transnational approach to the history of sport in Europe, we seize upon the 2012 Olympic Games as an opportunity to look back on Belgo-British contacts in sport since the Middle Ages. Contextualising this history within the wider Belgo-British political, economic and cultural contacts is, indeed, much more revealing than recounting a superficial story about the three medals the Belgian Olympic delegation actually obtained in London. We illustrate that transnational flows and contacts – crucial to the shaping and diffusion of sport – are not always reflected at the level of the Olympic Games. The cases of cycle racing and soccer demonstrate the divergent adoption and adaptation processes of specific sporting disciplines in Belgium and Britain. At the end of the paper, we also reflect on David Cameron's competitive sport policy in primary education, and raise the question whether the dissipation of public funds for elite sport – to the detriment of ‘Sport for All’ – is still defendable in times of government budgetary scarcity. 相似文献

A solid understanding of inferential statistics is of major importance for designing and interpreting empirical results in any scientific discipline. However, students are prone to many misconceptions regarding this topic. This article structurally summarizes and describes these misconceptions by presenting a systematic review of publications that provide empirical evidence of them. This group of publications was found to be dispersed over a wide range of specialized journals and proceedings, and the methodology used in the empirical studies was very diverse. Three research needs rise from this review: (1) further empirical studies that identify the sources and possible solutions for misconceptions in order to complement the abundant theoretical and statistical discussion about them; (2) new insights into effective research designs and methodologies to perform this type of research; and (3) structured and systematic summaries of findings like the one presented here, concerning misconceptions in other areas of statistics, that might be of interest both for educational researchers and teachers of statistics. 相似文献

Abstract The relative age effect is an uneven distribution of birth date favouring subjects born in the initial months of a selection year. This study compared the birth-date distributions between several subgroups of Basque football players to identify whether the relative age effect is influenced by age and/or skill level. The study comprised 13,519 players including 114 senior professionals from the Spanish league's AC Bilbao over 21 seasons; over the season 2005–2006, it comprised elite youth (n = 189) from the same club's academy; regional youth (n = 4382) U11–U14 locally federated players; school youth (n = 8834) U10–U11 locally registered school district players. Differences between the observed and expected birth-date distributions were tested based on data from the general Basque male population. Significant chi-square values were followed up by calculating odds ratios and 95% confidence intervals (CI) for the quartile and half-year distributions to examine subgroup differences in the relative age effect. Birth-date distributions of all groups of players showed a significant bias towards early birth in the selection year compared with the reference population (senior, χ2 3 = 24.4, P < 0.001; elite youth, χ2 3 = 59.1, P < 0.001; regional youth, χ2 3 = 41.4, P < 0.001; school youth, χ2 3 = 40.9, P < 0.001). Between-group comparison revealed that the relative age effect incidence progressively increased with a higher level of involvement in youth football. This bias represents a significant loss of potential youth football talent. 相似文献
