网络环境下多元化指导型教学模式的构建

网络环境下多元化指导型教学模式是我们以毛泽东同志"矛盾论"和"实践论"理论、"学与教"理论、建构主义理论为理论基础,经过五年多的不断探索,并结合现代远程开放教育的规律和各专业与课程的特点,逐步提炼、升华形成的.本模式突出网络平台的应用,突出教师的导学,充分考虑学生的个体差异,注重对学生自主学习的引导和学习能力的培养.在模式实施的过程中,教师应充分考虑到学生学习策略的多元化差异,积极改造学生学习策略中的不合理因素,及时制订或调整教学目标与教学策略,采取最适合的教学手段完成导学任务,使学生不仅学习专业知识,还可以掌握现代信息技术,形成团体协作精神,逐步提高综合能力和素质,从而实现人才培养的目标.     

课堂管理中纪律的问题与运用

我国中小学课堂纪律存在着很多问题,其典型问题是课堂纪律理论研究上的问题、教师的课堂纪律理念问题、中小学课堂纪律实际中的问题等,基于此,我们需要用课堂管理的理念去分析课堂纪律问题,从而使课堂纪律得到有效地贯彻执行。     

中小学课程的改革与评价考试体系的完善

为了保证课程改革的成功,评价考试体系的改革必须同步进行。应辩证地看待传统的考试方法,批判地继承传统考试的优点,要充分利用课程改革的有利时机,对传统的中小学评价考试观进行改革,还要引进相应的现代评价考试理论和方法,树立以激励学生发展,发展学生专长的评价考试观,使用先进的评价考试技术方法,建立与课程改革相适应的评价考试体系,从而更好地促进课程改革的顺利进行。     

棉花施用惠满丰有机复混肥增产效应研究

在当季不施肥,皮棉产量50kg/667m~2以上的生产条件下,棉花施用惠满丰有机复混肥30-70kg/667m~2,伏前桃增加1-1.5个,株高增加9.9-17.1cm,茎粗增加0.2-0.8mm,有效果枝增加约1.3个,单株成铃数增多1.1-3.1个,单铃重约增加0.4-0.5g,霜前花率提高3-9个百分点,衣分、子指也有所提高,比对照增产皮棉14.1-31.8kg/667m~2,增幅27.4％-61.1％(平均45％)。在等养分量情况下,惠满丰有机复混肥肥效优于化肥。惠满丰有机复混肥的经济合理施肥量为70kg/667m~2。     

From natural numbers to numbers and curves in nature —I

The interconnection between number theory, algebra, geometry and calculus is shown through Fibonacci sequence, golden section and logarithmic spiral. In this two-part article, we discuss how simple growth models based on these entities may be used to explain numbers and curves abundantly found in nature     

“Montrose” child life protection unit: A treatment and assessment model in child abuse intervention

In New South Wales, Australia, the Department of Youth and Community Services is empowered by statute to deal with cases of child abuse and neglect. Its child protection services include the Montrose Child Life Protection Unit which is designed to support and complement the work of both the Intake Service, Field Service and most importantly the work of child protective facilities in the community. The service has intake crisis counselling and call out resources; maintains a central register; provides a facility for crisis residential care for children and families, diagnostic assessment, and a day programme. The emphasis in service delivery in New South Wales in the area of child protection is on multidisciplinary intervention. The Department of Youth and Community Services is involved in promoting interagency cooperation and co-ordination. Over and above a philosophy that underlies service delivery is the Montrose Unit's involvement in sensitising the community to the difficult and often demanding role of parenting. Montrose represents an attempt to create an environment where parenting myths can be examined from a reality base and strategies implemented for reeducation.
