地理决策是中学地理课堂教学的重点和难点。文章在阐释中学地理决策教学内涵的基础上,提出地理决策教学在知识衍生、能力培养及学习视角方面的三大特征。同时,引入霍尔三维结构模型,从时间维(决策教学水平阶段)、逻辑维(决策教学环节)和知识维(决策教学理论储备)三个维度建立地理决策教学的三维模式,其中逻辑维按“明确决策问题—提供决策依据—进行决策分析—确定决策方案—凝练决策方法”五步骤依次推进。 相似文献

山西处黄河中游,有中华民族＂文化摇篮＂之称,有得天独厚的历史文化积淀。中国科举隋大业元年（605年）始,清光绪三十一年（1905年）终,历经1300年,横跨唐、五代、宋、辽、金、元、明、清。作为一种考试制度延续上千年的历史,这在中国和世界历史上都绝无仅有。历代科举中,山西共产生3000余名进士,有40余人进入鼎甲。本文尝试对山西历代的状元、榜眼、探花的情况进行小考。 相似文献

This article describes a typical evening at the Clinica del Pueblo in the Hispanic neighborhood of Adams-Morgan in Washington, D.c. The Clinical del Pueblo began operating in 1983 in response to the urgen medical needs of Central American refugees arriving in the Washington D.c. area. The refugees bring with them severe trauma, fear, and health problems caused by the civil was and exacerbated by inadequate or non-existant health services. Approximately 80,000 Salvadoran refugees live in the area. They do not receive adequate health care for 3 reasons. 1) Because the US goverment is unwilling to recognize them as true refugees, they live with the constant threat of deportatin back to the violence from which they have fled. 2) Refugees lack the ability to pay for private care. 3) Langauage and culture create frightening barriers to health care for the refugees. For those who do seek care, these barriers can lead to the inadequate or incomplete diagnoses and poor compliance and follow-up. Plenty International and the Central American Refugee Center responded to these problems by organizing a free clinic to provide not only medical care but also a training course for volunteers. The director of the clinic organizes the course, the classes are taught by a variety of people including the clinic's volunteer physicians, nurses, and public health educators as well as graduates of previus training courses and people from the wider community. The services of the clinic reach only a small portion of the population in need. However, the fact that free medical services are now available to some Central American refugees make the Clinica del Pueblo an important program. 相似文献

Three-dimensional (3D) or volumetric visualization is a useful resource for learning about the anatomy of the human brain. However, the effectiveness of 3D spatial visualization has not yet been assessed systematically. This report analyzes whether 3D volumetric visualization helps learners to identify and locate subcortical structures more precisely than classical cross-sectional images based on a two dimensional (2D) approach. Eighty participants were assigned to each experimental condition: 2D cross-sectional visualization vs. 3D volumetric visualization. Both groups were matched for age, gender, visual-spatial ability, and previous knowledge of neuroanatomy. Accuracy in identifying brain structures, execution time, and level of confidence in the response were taken as outcome measures. Moreover, interactive effects between the experimental conditions (2D vs. 3D) and factors such as level of competence (novice vs. expert), image modality (morphological and functional), and difficulty of the structures were analyzed. The percentage of correct answers (hit rate) and level of confidence in responses were significantly higher in the 3D visualization condition than in the 2D. In addition, the response time was significantly lower for the 3D visualization condition in comparison with the 2D. The interaction between the experimental condition (2D vs. 3D) and difficulty was significant, and the 3D condition facilitated the location of difficult images more than the 2D condition. 3D volumetric visualization helps to identify brain structures such as the hippocampus and amygdala, more accurately and rapidly than conventional 2D visualization. This paper discusses the implications of these results with regards to the learning process involved in neuroimaging interpretation. 相似文献

自从克拉申提出语言学习（language learning）和语言习得（language acquisition）这对概念并加以区分以来，学术界一直在探讨两者的不同点，并试图通过比较，找出其中适合本民族、本国度学习第二语言的途径。本文认为：任何一门语言的学习和掌握都是“习得”和“学得”两者共同作用的结果；语言学习有两个层次，部分可以习得，而另一部分必须通过学习才能获得，母语的学习过程也是如此。语言学习过程中两个层次的观点对外语学习具有指导意义。 相似文献

3D打印技术的发展使得产品的设计、制造和传播更为便利化,但是也随之引发侵犯著作权的风险。根据产品设计文档进行3D打印产品的行为是否属于著作权法上的复制行为,抑或是产品制造行为,是判定其构成侵权的重要因素。对于美术作品或者实用产品的设计文档进行3D打印,将产生不同的法律后果。在3D打印领域,我们应当对于功能性产品的设计文档提供著作复制权保护,合理设定复制权保护范围,同时拓展合理使用和默示许可等著作权保护的豁免制度,以期通过3D打印增进社会公共利益。 相似文献
