网络环境下实践学习共同体模型的构建

我国高等教育培养的人才不能满足社会实践需求的问题已成为政府、教育主管部门和研究者重点关注问题。究其产生的原因主要可以归结为教学内容和教学方式陈旧上。文中提出以情境理论为基础,在网络环境下建构实践学习共同体,为学生创设未来职业中的问题情境,并通过自己的努力去给予解决,以此提升实践能力,缩小就业前的"适应期"。对网络环境下实践学习共同体的定义、特征进行了阐述,并对其模型进行了建构。

文化认同与东亚共同体的构建

欧洲一体化建设的成功使得越来越多的人关注区域共同体的建设,东亚共同体的构建也成为东亚国家众多有识之士的奋斗目标。但是,相对于欧洲一体化的成功,东亚共同体的构建却要艰难的多,主要原因之一就在于目前东亚各国缺乏文化上的认同。如果要想成功地实现东亚共同体的构建,文化认同是各国需要共同努力解决的一个重要问题。

Assessment of semi-empirical mass transfer correlations for pervaporation treatment of wastewater contaminated with chlorinated hydrocarbons

INTRODUCTION Chlorinated hydrocarbons, a class of widely used dry-cleaning liquids, industrial organic solvents, and degreasers, increasingly find their way into drinking water sources, thus posing a very serious health and environmental problem (Love and Eliers, 1982). These organic solvents are known for their stability in the environment and cancer-causing po- tency and cannot be effectively and economically eliminated by current conventional treatment tech- nologies. One of the few av…

The Durability of Conceptual Change in Learning the Concept of Weight in the Case of a Pulley in Balance

This study concerns the question of how teachers can help pupils to perceive the concept of weight (gravitation). Fifth and ninth graders were asked in a paper-and-pencil test to compare the weight of two objects suspended in a pulley-in-balance half a year after the learning intervention consisting of three successive pulley-in-balance demonstrations. The understanding, that some of the fifth graders seemed to have formed from the weight concept after the teacher-independent learning intervention, had almost totally vanished in the delayed study. In the demonstrations the pulley served as an efficient prosthetic device for thinking, helping pupils to pay attention to the behaviour of the whole system instead of looking only at the separate objects. In the ninth grade about 45% of the pupils achieved general understanding about the pulley in balance by transferring the scientific explanation from the pulley demonstrations to the paper-and-pen test. A learning-with-conflict model is proposed based on pupil's alternative explanations about a discrepant event. These explanations are then challenged with a conflicting event. When pupils see and understand how the concept works in different contexts it is possible for the pupils to reach a context independent conceptual change.
