Experimental evaluation of the effects of cooperative learning on kindergarten children's mathematics ability

The aims of this study were to investigate the effects of cooperative learning on the mathematics ability and cooperative social behaviours of kindergarten children and to evaluate teachers’ perspectives on the application of the program. One control (n = 17) and one experimental group (n = 17) were studied. In the experimental group, a curriculum based on cooperative learning method activities was used. Significant improvements in mathematics abilities were found for children in the experimental group that utilised cooperative learning.     

贵阳花溪地区早三叠世碳、氧同位素特征及其古环境意义

对取自贵阳花溪地区改毛剖面上二叠统一下三叠统碳酸盐岩样品进行碳、氧同位素测定,利用所测数据建立相应的演化曲线.根据曲线变化情况,结合地质背景与岩性,着重探讨碳同位素变化的环境原因,并对研究区该时期古环境进行分析解释.研究表明,早三叠世初期,该地区海洋生态环境遭到严重破坏,但在Griesbachian早期有一次短暂恢复,而后又进入长期低迷的缺氧环境直到Smithian中期.     

高科技企业人才流失预警机制研究

以风险信息采集—风险预警指标库构建—风险评估—预警警报发布为逻辑思路阐述高科技企业人才流失风险预警模式。根据对人才流失风险的识别,从个体、组织、环境3个方面构建高科技企业人才流失风险预警指标体系,并利用层次分析法和熵权法对风险指标进行评估。最后,根据BP神经网络原理确定高科技企业人才流失风险预警模型,设计预警模型的构建步骤,进一步对风险等级及临界值进行设计和界定。

Playful fostering of 6- to 8-year-old students’ inductive reasoning

This paper focuses on a training program in inductive reasoning for first-grade students and presents the direct results as well as the longitudinal effects of the evaluation study. The training is based on Klauer's theory of inductive reasoning and on his “Cognitive training for children” concept (Klauer, 1989a). The training program consists of 120 problems which can be solved through inductive reasoning. The tools for the training exercises were selected to correspond with the age of the targeted cohort. The experimental group in the study consisted of 90 students, whereas the control group was made up of 162. An inductive reasoning test was used in the pre- and posttest as well as in the follow-up study (one year later). The test comprised 33 figural, non-verbal items (Cronbach α = .86). On the posttest, the experimental group significantly outperformed the control group by more than one standard deviation. The experimental group scored significantly higher in each skill area targeted by the training. The most noticeable development was found in system formation. No gender differences were detected on the pre- or the posttest. The effect size of the training program was d = 1.12. In the follow-up study, the experimental group still significantly outperformed the control group; however, their respective levels of development had not changed in this one-year period. Thus, the training effect proved to be stable over time independent of individual students’ original level of inductive reasoning. This study provided evidence that inductive reasoning could be developed very effectively at this early age.     

残酷屠戮还是高尚娱乐——古罗马角斗运动兴起的原因探析简

人类具有先天的暴力基因,但各民族个性不同,暴力基因的显现就存在程度差异。古罗马人以残酷的角斗长期延续而著名,除却暴力基因因素外,宗教祭祀、好斗性格、享乐至上、自然法精神、合法暴力思维等民族个性是角斗兴起流行的重要因素。     

浅谈如何把握幼儿早期教育的“度”

我们知道,幼儿教育跟小学教育是两个不同的领域,它需要不同的教学理念、教学方法和教学手段,但在现实中,幼儿教育的“小学化”倾向正日益严重,不少幼儿园的教学手段尤其是私人幼儿园几乎跟小学一模一样。这种倾向,对于幼儿的健康成长是福还是祸？是喜还是忧,值得家长、幼儿园乃至全社会的深思。

The rediscovery of Benevento Roman Theatre Acoustics

This study reports the acoustic history of the Benevento Roman theatre, from its origins in the Roman period to today. The theatre, built in the second century A.D., was abandoned following historical affairs – e.g. barbaric invasions – and natural events (earthquakes, floods, etc.). The building materials were used during the Langobardic Age for the construction of defensive walls and for the adornment of churches and buildings. During the following centuries some houses were built in the theatre. At the beginning of the 1900s, the dominating houses were demolished in order to bring to the light the buried parts of the theatre and to consolidate the structures. The recovery work ended only in 1950. The theatre is nowadays not only an ancient monument, but also the centre of important social activities with national and international festivals of music, dancing and drama. Using a software for architectural acoustic, and with a 3D theatre virtual model, we predicted the acoustic properties during the Imperial Age. With acoustic measurements carried out in situ, we evaluated the acoustic properties in the current state.     

Learning with immigrant children,families and communities: the imperative of early childhood teacher education

Abstract

This article reports on a longitudinal study spanning over 5 years, involving the design and implementation of an early childhood teacher education program model that engages a critical-ecological theoretical approach, a funds of knowledge perspective, and design-based methodology. This project aimed to promote equitable education for all children, and especially for young immigrant children encountering situations of oppression within the national and local educational contexts in Arizona. In this teacher education program, families, community members, researchers, pre-service teachers and teachers worked together to develop new modes of curricular activity, new spaces, new relationships, and new forms of movement among participants, as well as new circulations of literacy artefacts.
