外国中小学教育中绘本的运用

绘本作为国外小学和中学常见的课堂教材和课外读物,多年来在国内被误读为低幼读物.本文介绍了绘本的基本概念、叙事方式、阅读方式和推广途径,分析了国外绘本拥有大量作者和读者的原因,以期呼吁国内教育界能重视绘本的巨大教育价值.

京津冀水资源承载力模糊评价及关键驱动因素分析

从水资源供需-社会经济发展-生态环境复合系统中选取12个影响水资源承载力的因素构建指标评价体系,引入变权理论对2005—2016年京津冀地区水资源承载力进行模糊综合评价,并运用DEMATEL方法识别出其关键驱动因素。研究结果表明:(1)京津冀地区水资源2005—2009年的承载力综合评价值均小于0.4,处于严重超载状态;2009—2016年间的评价值在0.4和0.7之间,承载能力适中。(2)京津冀三地水资源承载力呈现波动上升的趋势,其中河北省的承载力增长趋势稍明显高于北京和天津。(3)在水资源承载力的影响因素中,供水模数、人口密度和城镇化率是关键驱动因素。最后,为提高京津冀水资源承载能力,实现水资源一体化保护,促进生态环境和社会经济协同发展提供政策建议。

郑珍诗与山谷诗学的关系

郑珍为诗,濡染于其师程恩泽,而与同代诗家祁寓藻、何绍基、曾国藩俱有宗宋倾向。但论者每谓郑诗师法韩、孟,并取元、白。其实郑诗取于韩盂,要在学问与脱俗两端,接引元白而去其俚俗,亦于二者为然。郑珍在创作上并溯韩、孟、元、白,却十分切合黄庭坚诗学强调学问和力避凡俗的基本主张,正是在这一根本的方面,郑珍诗显示了与山谷诗学的深层联系。

崔健：大众艺术中的“自由风格”

作为“中国摇滚乐之父”,崔健的艺术实践一直是在“商”与“狂”之间自由地穿梭,其不仅具有我们通常认为的先锋性特质,同时也具有注重商业性、娱乐性和技术性的大众化品格。用崔健的话说,这其实是一种充满世俗化人文关怀的“名副其实的大众艺术”。     

Individual participant data meta-analysis of the impact of educational interventions on pupils eligible for Free School Meals

Meta-analysis is the synthesis of findings from research projects, which enables an estimate of the average or pooled effect across various studies. This study presents findings from the intention to treat analysis for a series of educational evaluations in England using a two-stage meta-analysis with standardised outcome data and individual participant data meta-analyses. The research estimates the overall impact of educational trials on pupils eligible for Free School Meals (FSM) and the attainment gap in literacy and mathematics performance between FSM and non-FSM pupils based on analysis of 88 trials and data from over half a million pupils. For the meta-analyses, frequentist and Bayesian multilevel models were used to estimate the individual and pooled effect size across categories of explanatory variables such as age groups (key stages in England) and aspects of the type of interventions (one-to-one, small group, whole class). Results indicated that the overall impact of interventions on the literacy outcomes of FSM pupils was positive, with a pooled effect size of 0.06 (0.03, 0.08). However, for mathematics, no overall effect on FSM pupils was observed. Analysis of the attainment gap indicated that literacy outcomes for FSM pupils were improved by interventions marginally more than for non-FSM pupils (pooled attainment gap 0.01 (−0.01, 0.04)). The risk of bias assessment showed that estimates were consistent across different methodological approaches. Overall, evidence from this study can be used to identify, test and scale educational interventions in schools to improve educational outcomes for disadvantaged pupils.
