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.     

论早期贵阳城市的兴起与文化基础

文化和它衍生出来的环境,始终在贵阳不同时期发展的进程中起着举足轻重的作用。历史上郡国并存、土流并治的格局,助推了黔中地区人类早期城邑聚落的萌芽。魏晋之际大姓势力的崛起,频繁的民族迁徙与文化交流,为贵阳地区早期城市的发展奠定了经济与文化基础。唐代推行羁縻州制,从制度文化上给予了民族地区城市发展的空间,唐武德三年（620年）在今贵阳地置矩州,一直延续到宋代,直至明初建省,这种局面才发生改变。     

清末民初(1897-1915)的农学报刊及对现代农业科技的传播

【目的】研究了清末民初(1897-1915)的农学报刊,探求了农学报刊与中国现代农业发展的关系。【方法】采用文献调研和对比分析等方法研究了农学报刊在中国创办、发展、传播的基本状况及其历史作用。【结果】农学报刊引入了现代西方农业理念,推动了中国现代农业发展,促进了社会进步。【结论】清末民初的农学报刊促进了现代传播业的发展,同时也深刻地影响了我国的农业现代化进程。     

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.     

Evaluating construct validity and internal consistency of early childhood individualized family service plans

This study presents evidence regarding the construct validity and internal consistency of the IFSP Rating Scale (McWilliam & Jung, 2001), which was designed to rate individualized family service plans (IFSPs) on 12 indicators of family centered practice. Here, the Rasch measurement model is employed to investigate the scale's functioning and fit for both person and item diagnostics of 120 IFSPs that were previously analyzed with a classical test theory approach. Analyses demonstrated scores on the IFSP Rating Scale fit the model well, though additional items could improve the scale's reliability. Implications for applying the Rasch model to improve special education research and practice are discussed.     

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。
