Are boys that bad? Gender gaps in measured skills,grades and aspirations in Czech elementary schools
Petr Matějů 《British Journal of Sociology of Education》2015,36(6):871-895
This article examines gender gaps in academic performance (grades in mathematics and reading) between boys and girls of ninth-grade elementary schools in the Czech Republic. Our analysis is based on 2003 data from the Programme for International Student Assessment, encompassing the academic performance and family background of ninth-grade pupils. Similar to research on other countries, we find that girls strongly outperform boys in grades in Czech language, but that this gender gap is not explained by measured ability in reading nor on family background or student attributes. We also find gender bias in mathematics grades, after controlling for measured ability and other factors. Girls are also substantially more likely than boys to apply to secondary grammar schools, as well as aspire to a college education, even after controlling for measured ability. We put forward a number of theoretical perspectives that shed light on the possible causes of these empirical findings. 相似文献

To determine the effect of circadian rhythm on neuromuscular responses and kinematics related to physical tennis performance, after a standardised warm-up, 13 highly competitive male tennis players were tested twice for serve velocity/accuracy (SVA), countermovement vertical jump (CMJ), isometric handgrip strength (IS), agility T-test (AGIL) and a 10-m sprint (10-m RUN). In a randomised, counter-balance order, tennis players underwent the test battery twice, either in the morning (i.e., AM; 9:00 h) and in the afternoon (i.e., PM; 16:30 h). Paired t-tests were used to analyse differences due to time-of-day in performance variables. Comparison of morning versus afternoon testing revealed that SVA (168.5 ± 6.5 vs. 175.2 ± 6.1 km · h?1; P = 0.003; effect size [ES] = 1.07), CMJ (32.2 ± 0.9 vs. 33.7 ± 1.1 cm; P = 0.018; ES = 1.46), AGIL (10.14 ± 0.1 vs. 9.91 ± 0.2 s; P = 0.007; ES = 1.23) and 10-m RUN time (1.74 ± 0.1 vs. 1.69 ± 0.1 s; P = 0.021; ES = 0.67) were significantly blunted during the morning testing. However, IS was not affected by time-of-day (P = 0.891). Thus, tennis performance may be reduced when competing in the morning in comparison to early evening. Therefore, coaches and tennis players should focus on schedule the SVA, power, speed and agility training sessions in the afternoon. 相似文献

Nonreinforced exposure to a cue tends to attenuate subsequent conditioning with that cue—an effect referred to as latent inhibition (LI). In the two experiments reported here, we examined LI effects in the context of conditioned taste aversion by examining both the amount of consumption and the microstructure of the consummatory behavior (in terms of the mean size of lick clusters). The latter measure can be taken to reflect affective responses to, or the palatability of, the solution being consumed. In both experiments, exposure to a to-be-conditioned flavor prior to pairing the flavor with nausea produced by lithium chloride attenuated both the reduction in consumption and the reduction in lick cluster sizes typically produced by taste aversion learning. In addition, we observed a tendency (especially in the lick cluster measure) for nonreinforced exposure to reduce neophobic responses to the test flavors. Taken together, these results reinforce the suggestion from previous experiments using taste reactivity methods that LI attenuates the effects of taste aversion on both consumption and cue palatability. The present results also support the suggestion that the failure in previous studies to see concurrent LI effects on consumption and palatability was due to a context specificity produced by the oral taste infusion methods required for taste reactivity analyses. Finally, the fact that the pattern of extinction of conditioned changes in consumption and in lick cluster sizes was not affected by preexposure to the cue flavors suggests that LI influenced the quantity but not the quality of conditioned taste aversion. 相似文献

Libraries continue to be an important source of books for young people, though relatively little is known about how gender and age influence visitation frequency for this purpose. In addition, while supporting children to choose books is part of the role of both school and public librarians, little is known about the strategies and processes children use to select books, and the beliefs and attitudes that underpin them. Findings from the 2016 Western Australian Study in Children's Book Reading offer insights into these areas that can support librarians to guide book choice, and they encourage targeted intervention to ensure that boys and older children make use of their libraries to support their literacy growth. 相似文献

Four experiments were conducted to explore outcome-specific transfer from causal predictive judgments to instrumental responding. A video game was designed in which participants had to defend Andalusia from navy and air force attacks. First, they learned the relationship between two instrumental responses (two keys on a standard keyboard) and two different outcomes (destruction of the ships or destruction of the planes). Then they learned to predict which of two different stimuli predicted which outcome. Finally, they had the opportunity of making either of the two instrumental responses in the presence of either stimulus. Transfer was shown as a preference for the response that shared an outcome with the current stimulus. The presentation of the stimulus during the test produced a decrease in the overall rate of response. Responding to a neutral stimulus in Experiments 2 and 3 suggested that this overall decrease in responding was due to a combination of the time needed to process the meaning of the stimulus and the activation of the representation of the outcome in the presence of the stimulus during the test. Transfer between predictive judgments and instrumental responding mirrors the outcome-specific Pavlovian instrumental transfer observed in conditioning studies with rats. 相似文献

University–Industry Collaboration (UIC) has been identified as an essential item on Malaysia’s agenda for transforming itself into knowledge and innovation-based economy. However, despite the efforts, most initiatives have had limited results. This paper reports on an explorative study that sought to understand the contemporary realities of UIC in the Malaysian context. In particular, the study identified the expectations and impediments to UIC, from the perspectives of three groups of stakeholders – the academics, the industry players and policymakers. The findings reveal a number of barriers, including cultural differences, perceived lack of academic expertise and reputation, an inadequacy of institutional policies and regulations, lack of trust, issues of intellectual property rights, and the lack of an appropriate reward system. This paper concludes by proposing policy recommendations and strategies that could be used by the government, university, and the industry to promote further and foster university-industry collaborative opportunities and initiatives. 相似文献

Among the more relevant questions in educational research is how the governments and policy‐makers in transition countries address the high educational inequality inherited from the past and what policies they develop in order to reduce the strong effects of the background family and the type of school on students' achievements, their aspirations and their chances of succeeding in the most important educational transitions. This paper addresses one of the most topical issues in this area, namely the social selectivity of Czech basic and secondary education. Special attention is paid to the role of ‘multi‐year’ gymnasia. The results of analyses carried out on data from the Programme for International Student Assessment 2000 study corroborate the initial hypothesis according to which multi‐year gymnasia, introduced into the Czech educational system after 1989, represent one of the main sources of the variation in students' achievements at the end of compulsory education. However, this variation can be almost entirely accounted for by the specific socio‐economic background of the students. The same holds true for their future aspirations. The results of the analysis support the conclusions of the OECD Review of National Policies for Education from 1996. 相似文献

It has been increasingly recognised that sexual violence in schools is one of the major concerns with regard to promoting sexual and reproductive health and rights. This paper examines how boys and girls define, experience, and interpret sexual violence in a secondary school in Addis Ababa, Ethiopia, and considers from their perspectives, how sexual violence can be addressed effectively in formal educational settings. Fifteen in-depth interviews and two focus group discussions revealed how these views can be strikingly different for boys and girls: boys sharing a theoretical and instrumental view on sexual violence, as opposed to girls’ emotional views based on their experiences. This major difference in understanding complicates teaching about sexuality, and leaves room for sexual violence to remain tolerated in schools. Nevertheless, all students express the need to learn openly about sexuality, and particularly to reflect on the contradicting messages they receive from their environment. 相似文献
