This paper presents findings from an ethnographic study of the adjustment journey of international postgraduate students at a university in the South of England, which involved interviews and participant observation over a 12-month academic year. It was discovered that the initial stage of the sojourn1 was not characterised by feelings of excitement, as suggested by the U-curve model (and its successors): though such feelings were present, they were overwhelmed by negative symptoms more commonly associated with culture shock. The implications of these findings for support structures in higher education are discussed. 相似文献

A prospective survey was conducted to identify predictors of university students' grade point average (GPA) using separate samples of female (N = 472) and male (N = 142) students over 9 months. Big five personality traits and achievement motivation were measured. Correlations show that conscientiousness (C) and achievement motivation explained variation in GPA. Latent variable structural equation modelling showed that the effect of C on GPA is fully mediated by achievement motivation for both female and male students. Invariant factor and structural mediation models across the female and male groups are also reported. Finally, the mediation model is shown to remain significant after scholastic achievement is controlled. The findings are interpreted within the framework of Neo‐Socioanalytic theory.

Working memory (WM) plays a crucial role in supporting learning, including reading. This study investigated the influence of reading acceleration and WM training programs on improving reading skills and WM abilities. Ninety-seven children in third grade were divided into three study groups and one control group. The three study groups each received a different combination of two training programs: only reading acceleration, WM followed by reading acceleration, and reading acceleration followed by WM. All training programs significantly improved reading skills and WM abilities. Compared with the control group, the group trained with only the reading acceleration program improved word accuracy, whereas the groups trained with a combination of reading and WM programs improved word and pseudo-word fluency. The reading-acceleration-alone group and the WM-program-followed-by-reading-acceleration group improved phonological complex memory. We conclude that a training program that combines a long reading acceleration program and a short WM program is the most effective for improving the abilities most related to scholastic achievement. 相似文献

High levels of teacher–child conflict have repeatedly been found to amplify children's aggressive behaviour. Up to now, however, research on possible mechanisms explaining this link is largely lacking. The current study aimed to test whether children's self‐esteem is an intervening mechanism. Participants were 139 children (70 boys, M age = 6.18 years) and their teachers from 35 classes in 19 schools who were followed longitudinally throughout first grade. Teacher–child conflict was measured during the first trimester (October to December), children's self‐esteem (three child interviews) during the second trimester (January to March) and children's aggressive behaviour during the first and third trimester (April to June). Teacher–child conflict had a significant indirect effect on changes in children's aggressive behaviour across first grade through its effect on children's self‐esteem.

Frege's theory of indirect contexts and the shift of sense and reference in these contexts has puzzled many. What can the hierarchy of indirect senses, doubly indirect senses, and so on, be? Donald Davidson gave a well‐known ‘unlearnability’ argument against Frege's theory. The present paper argues that the key to Frege's theory lies in the fact that whenever a reference is specified (even though many senses determine a single reference), it is specified in a particular way, so that giving a reference implies giving a sense; and that one must be ‘acquainted’ with the sense. It is argued that an indirect sense must be ‘immediately revelatory’ of its reference. General principles for Frege's doctrine of sense and reference are sated, for both direct and indirect quotation, to be understood iteratively. I also discuss Frege's doctrine of tensed and first person statements in the light of my analysis. The views of various other authors are examined. The conclusion is to ascribe to Frege an implicit doctrine of acquaintance similar to that of Russell. 相似文献

This study investigated the effects of video game play on aggression. Using the General Aggression Model, as applied to video games by Anderson and Bushman, [2002] this study measured physiological arousal, state hostility, and how aggressively participants would respond to three hypothetical scenarios. In addition, this study measured each of these variables multiple times to gauge how aggression would change with increased video game play. Results showed a significant increase from baseline in hostility and aggression (based on two of the three story stems), which is consistent with the General Aggression Model. This study adds to the existing literature on video games and aggression by showing that increased play of a violent first person shooter video game can significantly increase aggression from baseline. 相似文献

Should low-achieving students be promoted to the next grade or be retained (held back) in the prior grade? This special section presents a discussion of the application of marginal structural models to the challenging problem of estimating the effect of promotion versus retention in grade on math scores in elementary school. Vandecandelaere, De Fraine, Van Damme, and Vansteelandt provide a didactic presentation of the marginal structural modeling approach, noting retention is a time-varying treatment because promoted low-achieving students may be retained in a subsequent grade. Steiner, Park, and Kim's commentary presents a detailed analysis of the treatment effects being estimated in same-age versus same-grade comparisons from the perspective of the potential outcomes model. Reshetnyak, Cham, and Kim's commentary clarifies the conditions under which same-age versus same-grade comparisons might be preferred; they also identify methods of further improving the estimation of retention effects. In their rejoinder, Vandecandelaere and Vansteelandt discuss tradeoffs in comparing the promoted and retained groups and highlight sensitivity analysis as a method of probing the robustness of treatment effect estimates. Our hope is that this combined didactic presentation and critical evaluation will encourage researchers to add marginal structural models to their methodological toolkits. 相似文献

During early adolescence, most public school students undergo school transitions, and many students experience declines in academic performance and social-emotional well-being. Theories and empirical research have highlighted the importance of supportive school environments in promoting positive youth development during this period of transition. Despite this, little is known about the proximal social and developmental contexts of the range of middle grade public schools US students attend. Using a cross-sectional dataset from the eighth grade wave of the Early Childhood Longitudinal Study—Kindergarten Cohort 1998–1999, the current study examines the middle grade school social context from the perspectives of administrators and teachers in public schools with typical grade configurations (k–8 schools, middle schools, and junior high schools) and how it relates to students’ perceptions of school climate. We find that administrators and teachers in k–8 schools perceive a more positive school social context, controlling for school structural and demographic characteristics. This school social context, in turn, is associated with students’ perceptions of their schools’ social and academic climate. Implications for educational policy and practice are discussed. 相似文献
