A census and survey of schools in the district of Ga, Ghana, explored the nature and extent of private education, and compared inputs to public and private schooling. Three quarters of all schools found were private, with almost as many unregistered private as government schools. Several important differences between registered and unregistered private schools were noted, including age, fee levels charged, teacher salaries and class size. A range of inputs, such as teacher activity, availability of desks, chairs, libraries, toilets and drinking water, were used to compare inputs to government, unregistered and registered private schools. Some conclusions are explored about the potential role for the private sector in helping meet “education for all” targets.  相似文献

When students are grouped into school tracks, this has lasting consequences for their learning and later careers. In Germany to date, some groups of students (boys, ethnic minority students) are underrepresented in the highest track. Stereotypes about these groups exist that entail negative expectations about their suitability for the highest track. Based on the shifting standards model, the present research examines if and how stereotypes influence tracking recommendations. According to this theory, members of negatively stereotyped groups will be judged more leniently or more strictly depending on the framing of the judgment situation (by inducing minimum or confirmatory standards). N = 280 teacher students participated in a vignette study in which they had to choose the amount of positive evidence for suitability they wanted to see before deciding to recommend a fictitious student to the highest track. A 2 (judgment standard: minimum vs. confirmatory) × 2 (target student’s gender: male vs. female) × 2 (target student’s ethnicity: no migration background vs. Turkish migration background) between-subjects design was used. No effects of target gender occurred, but the expected interaction of target’s ethnicity and judgment standard emerged. In the minimum standard condition, less evidence was required for the ethnic minority student to be recommended for the highest track compared to the majority student. In the confirmatory standards condition, however, participants tended to require less evidence for the ethnic majority student. Our experiment underlines the importance of the framing of the recommendation situation, resulting in a more lenient or stricter assessment of negatively stereotyped groups.

Performance management systems have been an inevitable consequence of the development of government research evaluations (GREs) of university research, and have also inevitably affected the working life of academics. The aim of this paper is to track the development of GREs over the past 25 years, by critically evaluating their adoption in the UK and Australian higher education sector and their contribution to the commodification of academic labour, and to highlight the resultant tensions between GREs and academic freedom. The paper employs a literature-based analysis, relying on publicly available policy documents and academic studies over the period 1985–2010. GREs are a global phenomenon emanating from new public management reforms and while assessments of university research have been welcomed, they have attracted critique based on their design, the manner in which they have been applied, and the unintended consequences of their implementation on academic freedom in particular. Consistent with international research on the impact of GREs, Australian research assessments appear to be undoing the academic freedom that is central to successful research. Further empirical research on the impact of GREs on academics is urgently needed.  相似文献

Basic numerical representations are seen as the building block for the successful development of more complex numerical and arithmetic competencies. Extending previous studies focusing on improving basic numerical representations by means of embodied training schemes, the current study focused on an embodied training of children’s place-value understanding. In this vein, 49 secondgraders were trained on solving a number line estimation task by stepping on different fields of a dance mat allowing for separate estimations of tens and units with more effort needed to step on the tens. In a partially randomized cross-over design, two control conditions were used to controll for training effects caused exclusively by the numerical content trained or the use of the dance mat. Interestingly, results revealed specific training effects after both the embodied and the control conditions. However, training effects were significantly more pronounced after the embodied training, thereby providing further evidence for the benefit of an embodied training of the place-value structure of the Arabic number system.  相似文献

The work of Ball, Bowe and Gewirtz is probably the most important research to be published on the implications of recent ‘school choice’ reforms in England and Wales. One of their most notable conclusions points to the relationship between social class and school choice. Their conclusions are challenged on methodological grounds. First, it is not clear that their qualitative method can support the generalisation about class and choice which they make. However, even as regards more modest conclusions, difficulties arise with the operationalisation of their concepts. For the details of how particular families are fitted into their analytical framework raises severe problems. This leads to their judgements about the allocation of families to categories being controversial, hence undermining even localised conclusions about social class and school choice. Drawing on this analysis, general lessons are sketched for the conduct of qualitative research and its reporting to the research community.  相似文献

The present research examines discordant acculturation attitudes of host society members and immigrants as an antecedent to intergroup threat. Based on integrated threat theory and the concordance model of acculturation, we posited that discordance on culture maintenance and on desire for contact would predict intergroup threat beyond the influence of other antecedents of threat, such as in-group identification, knowledge, and negative contact. A study with 202 German host society members and 151 Turkish and Italian immigrants was conducted. In line with our assumptions, path analyses revealed that culture discordance and contact discordance contribute independently to the prediction of realistic threat, symbolic threat, and intergroup anxiety for host society members and immigrants. Moreover, differences in threat between cultures were mediated by the discordance in acculturation attitudes.  相似文献

The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 years, n = 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Groundwork Combat Time and Pause Time. Analysis of variance (ANOVA) one-way and the Tukey test, as well as the Kruskal-Wallis test and Mann-Whitney (for non-parametric data), were conducted, using P < 0.05 as significance level. The results showed that all analysed groups obtained a median of 7 (first quantile - 3, third quantile - 12) sequences of combat/pause cycles. In total time of combat, the result was: for Total Combat Time, Standing Combat Time and Gripping Time: Pre-Juvenile and Senior were significantly longer than Juvenile and Junior. Considering Displacement Without Contact, Junior was significantly longer than all other age groups. For Groundwork Combat Time, Senior was significantly longer than all other age groups and Pre-Juvenile was longer than Junior. These results can be used to improve the physiological performance in intermittent practices, as well as technical-tactical training during judo sessions.  相似文献
