基于GIS的华北-辽南土地潜力区土地适宜性评价

以华北-辽南土地潜力区为案例区，研究了GIS技术支持下基于多要素空间数据进行土地适宜性评价的方法与技术，评价对象包括土地限制因子、土地限制型、土地质量等和土地适宜类。根据研究区的自然地理和土地资源系统特征，选取气候、地形、灌排水、土壤和植被等五大类10个指标为评价因子；应用基于栅格数据模型的空间分析技术在1km²尺度建立评价因子基础数据库，并将评价原则用地图代数语言加以表达，形成了“要素数据”、“原则标准”与“分析技术”相结合的、逐级递进的评价技术流程。案例区实证研究表明：评价方法与技术切实可行，高质量的基础数据、合理的评价方法和有效的分析技术共同保证了评价过程的准确与高效；案例区的土地限制因子以土壤质地、水文与排水条件、坡度和灌溉条件为主，而土地适宜类则以宜农类、宜林牧类和宜农林牧类为主。     

灵活有效地开展地理“探究式教学”

把"探究式教学"引入地理课堂教学,应该把"探究式教学"的"精髓"渗入到地理课堂教学过程中,灵活应用,甚至化整为零,充分利用课堂有限的时间,有效开展地理"探究式教学"。使学生掌握探究的方法,形成探究意识。     

马尔库塞科技伦理观的理论逻辑

马尔库塞将当代科学技术当作一种新的控制形式,当作造成发达工业社会及其思想文化单向度的根源,当作工具理性和实证主义思想基础加以批判,正是在此基础上形成了一种以剖析科学技术的消极社会功能为着眼点的科技一社会伦理观。马尔库塞认为,当代科学技术的进步不仅已扩展至控制与调节系统,并创造出一些生活和权利形式,而且还导致“新阶级结构”的生成。同时这种技术理性形成了单向度的思维方式,而且还渗透到社会的总体结构和社会生活的各个方面,成为发达工业社会对人实行全面奴役和统治的思想基础。     

泉州湾桐花树种群抗氧化能力的比较

比较研究了泉州湾桐花树种群构件水平和个体水平不同龄级叶的脂质过氧化程度及抗氧化物含量,结果表明：在桐花树种群叶构件水平上过氧化程度较严重的是植株基部老叶,其次是中上部叶,膜脂质过氧化程度较低的是顶叶;从个体种群水平看植株叶的脂质过氧化程度较高的是刚进入繁殖期的植株;在构件水平上植株顶叶GSH含量和CAT活性表现最高,中部叶片次之,基部老叶较低,NO含量呈现与之相反的变化趋势;在个体种群水平上桐花树叶的GSH含量和CAT活性表现为开花期植株比未开花植株高,2~6片叶幼苗植株叶的抗氧化物含量最低.桐花树种群抗氧化能力的研究结果显示,进入繁殖生长的植株和2~6片叶幼苗植株宜作为泉州湾桐花树林的重点保护对象.     

A small-scale exploratory study of educator’s perceptions and expectations of summer-born children in the reception classes of three English primary academies and the strategies used to support them

This small-scale interpretative study, carried out in the reception classes of three English primary academies, examined educator perceptions of summer-born children, their expectations of children on entry to reception classes and whether those expectations were age differentiated. It also investigated the support and intervention strategies used for children in reception classes. The findings showed that the children were viewed in terms of a whole cohort and expectations of the children were not age differentiated, raising equity issues. Educators were pressurised by the ‘school readiness’ metanarrative so that although they spoke of a focus on children’s personal, emotional and social development in practice, their focus was on children’s acquisition of literacy and numeracy skills in whole-class activities and intervention groups, resulting in a conforming, instrumentalist pedagogy at odds with their assertions of a play-based curriculum.     

浅析我国高等教育中的阶层差距

教育的阶层差距在我国高等教育阶段更加突出地表现出来,主要因为收入情况影响了家庭的教育经费支出,家庭成员的文化、政治资源占有情况也对教育造成相当影响。目前补偿原则是改变阶层高等教育不平等的尝试。     

The antithesis of inclusion? The emergence and functioning of ADHD special education classes in the Swedish school system

The neuropsychiatric paradigm has substantial impact on schools. The increase in the number of pupils being diagnosed with attention-deficit/hyperactivity disorder (ADHD) is an expression of the medicalisation of deviance. There is also an increase in educational classes specially designed to meet the needs of children with ADHD. This is contrary to the notion of inclusion and in conflict with the Swedish school law. Thus, it is important to obtain knowledge about Swedish ADHD classes. A questionnaire was sent to all Swedish municipalities (290, response rate 76%) regarding schooling for pupils with ADHD. As many as 40 Swedish municipalities have classes specifically designed for pupils with ADHD. Although the classes are said to be specifically designed for ADHD problems, they are not properly evaluated. Municipalities with ADHD classes also exhibit ambivalence towards these classes. The emergence, prevalence and functioning of the ADHD classes are discussed in light of the notion of inclusive education.     

将研讨式教学方法带进研究生课堂教学

研讨式课堂教学是以研讨为基本特征的一种教学活动。研讨式课堂教学是为研究而学习,为教学而学习。通过研讨式教学,使学生对知识的理解更加深入,同时也提高了科研能力,获取一些科研创见。     

运用积极行为支持改善随班就读儿童行为问题

随班就读是我国特殊儿童接受义务教育的主要形式。随班就读学生的问题行为一直是妨碍我国随班就读教学质量提高的重要问题。积极行为支持是使用教育和系统改变的方法,提高生活质量和最小化问题行为的应用科学。它的应用范围包括个人、班级和学校范围的积极行为支持。     

对辽宁高职院校冬季体育教学的探索

辽宁地处祖国东北,冬季漫长而寒冷。由于一些客观因素的影响,使冬季体育教学成为高职院校一个薄弱环节。存在冬季体育课内容贫乏、形式单一,没有明显地域特点等问题。因此,提出几点冬季体育教学的建议。
