Conversation and Conflict: Supporting Authentic Dialogue in the Classroom

This paper presents an exploratory study of MSW students who self‐identified as having political/religious world views differing from what they perceived to be dominant at their school. A goal was to learn about conditions that fostered or inhibited authentic speech for those students. A secondary goal was to learn how students dealt with their political views differing from political positions taken by the profession. Eleven student volunteers participated in structured interviews. Qualitative analysis of these allowed the construction of themes concerning both how faculty may discourage and how faculty support expression of minority views.     

Emotionally Intense Science Activities

Science activities that evoke positive emotional responses make a difference to students’ emotional experience of science. In this study, we explored 8th Grade students’ discrete emotions expressed during science activities in a unit on Energy. Multiple data sources including classroom videos, interviews and emotion diaries completed at the end of each lesson were analysed to identify individual student's emotions. Results from two representative students are presented as case studies. Using a theoretical perspective drawn from theories of emotions founded in sociology, two assertions emerged. First, during the demonstration activity, students experienced the emotions of wonder and surprise; second, during a laboratory activity, students experienced the intense positive emotions of happiness/joy. Characteristics of these activities that contributed to students’ positive experiences are highlighted. The study found that choosing activities that evoked strong positive emotional experiences, focused students’ attention on the phenomenon they were learning, and the activities were recalled positively. Furthermore, such positive experiences may contribute to students’ interest and engagement in science and longer term memorability. Finally, implications for science teachers and pre-service teacher education are suggested.     

知识分子的和谐理想及其文学表达——以郭沫若的《女神》为例

近百年来中国知识分子追求的社会理想之一便是"和谐"。从郭沫若来看,"和谐"既是《女神》彰显的社会理想,也是其强调的人生追求。"和谐"包括个体的"人的和谐"和整体的"社会的和谐"。个体的"和谐"需通过正视自我、追求自由、坚守平等、破旧立新、超越现实,以达到人的情感与意志、道德、信仰相和谐。社会整体的"和谐"主要通过将物人化、将人神化、人与物相统一、"天人一体"化,以促进社会政治体制的合情合理化,从而达到民族的复兴和社会全体的自由欢唱。     

Does academic self-concept drive academic achievement?

Gaps in GCSE attainment have long been the concern of policy makers, academics, and social commentators, largely due to the importance of these exams for setting children on their future academic and career pathways. In the past a wide range of factors relating to the pupils, their families, and their schools have been found to account for differences in GCSE attainment. In this paper we examine the role of pupils’ beliefs in their own academic ability (academic self-concept). Using Next Steps data, we examine whether pupils with higher academic self-concept do better or worse in their GCSEs than pupils with lower academic self-concept. Results show that on average, controlling for other characteristics, having high academic self-concept increases GCSE scores by four grades. When we compare academic self-concept to measured achievement we find that both high and low attainers have higher probabilities of achieving five A*–C GCSEs and higher GCSE point scores on average if they have high academic self-concept than similarly able students who have lower academic self-concept.     

可控整流中晶闸管参数的选择及其应用

晶闸管的选择参数很多,但用于可控整流时,主要是额定电流、额定电压的计算与选择。晶闸管由于过电流过电压能力低,文常常工作在不同的电流波形情况下,给额定电流的选择带来一定的困难,如若额定值选择不当,会造成不必要的损失或浪费。根据实际工作条件,在满足需要的前提下,应尽量降低晶闸管的定额,以减少设备投资。     

The first seven years at school

This paper assesses the cumulative long-term impact of successive years of high quality provision in schools. This was achieved by looking at the consequences, up to the age of 11 (Year 6), of attending a school where there was high or low value-added in each of the 7 years of primary education in England. Multi-level models for thousands of pupils were set up in which the relative contribution of the school was estimated each year, as was the impact of attainment levels reached in each previous year. The analyses indicated that: relative progress each year was important but progress in the earliest years was the most important. Good progress in the first year at school was still detectable in the last year of primary schooling. Boosts or setbacks to progress in one year can be added or subtracted to progress in another. The relative importance of school for maths and reading were similar but smaller for vocabulary. The analyses suggest that teachers are of key importance when considering educational effectiveness and the implication for policy makers and school effectiveness researchers are discussed.

Determinants of private school participation: All about the money?

For those who grew up in Britain in the latter half of the twentieth century, there is known to be a strong association between social class or family income and attending a private school. However, increasing private school fees and promotion of school choice in the state sector have potential implications for the predictors of participation in private schooling in the twenty-first century. In this article, through analysis of rich, longitudinal data from a recent, representative birth cohort study, we provide new evidence on this issue. Given the high and rising fees required to send a child to private school, one might think that the decision is entirely connected with financial resources. However, while these remain an important factor, we argue that other determinants are also important. In particular, we highlight the importance of parental values and geographical proximity to high-quality state school alternatives: a one standard deviation increase in levels of parental traditional values is associated with a 2.5 percentage point higher probability of their child attending a private school, while each minute of additional travel time to the nearest state school judged ‘Outstanding’ by England’s schools inspectorate is associated with a 0.2 percentage point higher probability of attending a private school. We also examine the characteristics of those who ‘mix and match’ state and private schooling, noting their similarity to private school attendees in terms of their values but lower levels of financial resources.     

后激活增强效应的生理机制、诱导条件及适用运动员特点研究

爆发力是快速力量为主导的体育项目中决定运动成绩的重要因素,爆发力的任何变化都有可能造成冠军或者名次的改变,因此如何在赛前准备活动中更大程度地提高运动员比赛时的爆发力成为近年来研究的重点。不断去追求和探索更加合理的、有效的激发运动员爆发力的方法和手段,成为运动员和教练员们所关注的内容。随着学界对于后激活增强效应(postactivation potentiation,PAP)的研究愈发深入,发现后激活增强效应有可能成为通过赛前准备活动提高运动员在比赛中爆发力的突破点,对PAP的功能及其在运动能力上应用的关注和研究与日俱增。许多研究人员在运动试验中,通过诱导出PAP提高了运动员的竞技表现,但因这些实验的变量选取纷繁复杂,研究多集中在PAP对运动能力即时性提升的效果,而PAP诱导效果的影响因素尚不明确。从生理机制、诱导条件与适用运动员特点3个方面进行梳理,分析研究PAP产生的生理机制,PAP进行诱导刺激所需的条件,以及适合通过PAP提高运动水平的运动员的特点,旨在为我国教练员和运动员在竞技训练实践中合理利用PAP提供有益参考。
