从初中生解题路径看知识掌握的质量及存在问题

问题现代认知心理学理论认为,学生应用知识解决问题能力的高低,不仅与贮存知识的数量有关,还与贮存知识的概括程度、索引方式、相互关联度等可有效利用的属性有关,即与知识掌握的质量有关。课堂中经常能听到学生的反映:“上课能听懂,书上的练习也会做,但就是碰到综合性题目不知     

Environmental impact assessment of ecological migration in China: a survey of immigrant resettlement regions

Implementation of ecological migration (eco-migration) policies may improve the fragile ecological environment of emigration areas; however, it also places enormous pressure on the human-environment systems in immigrant resettlement regions. Via the application of participatory rural appraisal (PRA) methods, ecological footprint (EF), and stochastic impacts by regression on population, affluence, and technology (STIRPAT) models, 21 villages of Huanjiang County in Guangxi Zhuang Autonomous Region, China were used in this research as a case study area for the environmental appraisal of eco-migration policies in immigrant resettlement regions. Results show: (1) In the past 20 years of implementing eco-migration policies, the EF per capita constantly increased, the biocapacity (BC) per capita constantly decreased, and the ecological deficit gradually increased, indicating an extremely negative impact of eco-migration projects on the ecological environment in the immigration areas. (2) Cropland and forest land are the most important components of the per-capita EF. The per-capita EF of cropland experienced overall a first increasing and then decreasing trend, and the per-capita EF of forest land constantly increased and showed the most rapid increase among all types of EF in the last two decades. (3) The proportion of per-capita EF of different types of productive land is in the order of forest land > cropland > carbon uptake land > built-up land > grazing land from high to low, and this is a significant change from the original order of cropland > forest land > carbon uptake land > grazing land > built-up land. (4) Because of unequal possession of ecologically productive resources, the overall per-capita EF, overall per-capita BC, overall per-capita ecological deficit of productive land use by migrants, and their component values of different types of productive land use are all lower than the corresponding values of the natives. The ecological deficit of natives is more severe than that of migrants. (5) Whereas population growth and overexploitation of resources lead directly to the increased pressure on the ecological environment in the immigration areas, increasing nonagricultural income and improving the consumption structure can reduce the dependence of farmers on the land, thus inhibiting the increase of EF.

高校管理体制改革的意义及动力

“高校管理体制”有确定的内涵和外延,不能任意理解或加以泛化。明确这一概念,有助于在机构改革过程中抓住主要矛盾。体制改革虽然属于保障性改革,但具有为教学、科研等主体性改革扫除障碍、创造条件的作用。管理体制改革与人事制度改革虽然都属于保障性改革,但仍然有一个先后、主次的问题。因此,“体制改革是关键”。高校自身缺乏主动改革管理体制的内在动力,需要通过外部行政力量强制推行。

基于独立学院电专业类群式课程体系的构建

独立学院因办学时间短、教学资源缺乏、师资力量不足,不易打出品牌。该文从课程设置的角度出发,以电专业为例建立了类群式课程体系,该课程体系既可以有效地节省教学资源和弥补师资的缺口,还形成了一定的教学特色。但它对于教师在多学科方面的知识体系的深度了解,提出了更高的要求。

中国当代文学理论批评40年

中国当代学理论批评史分为三个时期；化革命前十七年学理论的特点之一是许多学理论家以既清醒又混沌的心智为共同的思维特征和以社会学评论为主要方法；化革命结束后经历了从恢复期到蜕变期到收获期的发展阶段，初步出现了百家争鸣的局面。     

物理学史教育对培养学生人文素养的作用

中学物理是一门教给学生物质结构和运动基础知识并传授科学思维方法的学科. 人文指人类社会的各种文化现象,笔者所使用的教材(人教社试验修订本必修加选修)中含有丰富的物理学史知识,若教师重视并加以深化利用则对学生人文素养的培养关系重大,且一生受益匪浅.
