数学活动经验及其对教学的影响

数学活动经验是数学学习的产物,从维度上分为数学思想方法、数学思维方法、数学活动过程中的体验;又表现为静态和动态两个层面。重视数学活动经验的教学意义在于:扩展学生的认知结构,提高教学设计的实效性,彰显个性化的学习,生成课程资源。其教学策略是:让学生亲历数学活动,增加交流的机会,开展反思与评价。     

经、经学与中国传统教育

从历史发展来看,经、经学从其产生之时起即与教育密切相关。"经"的确立,实际上是一个由"泛称"向"专称"转化的过程,"经"就其实际内容而言,多为"史"。就"经"在古代社会的地位而言,是"载道之经";就其具体作用于社会的方式而言,则是"教科书"。经学是一套特殊的学术文化体系,其意识形态的功能与教育功能统一而不可分。两汉的儒者通过经学对六经加以适当地诠释,使六经的知识系统很好地适应了汉代封建统治帝国的需要,这是中国传统教育以"经"为教育模式的基本实现路径。

Computer simulation of active suspension based on the full-vehicle model

The current method to solve the problem of active suspension control for a vehicle is often dealt with a quarter-car or half-car model.But it is not enough to use this kind of model for practical applications.In this paper,based on considering the influence of factors such as,seat and passengers a MDOF(multi-degree-of-freedom)model describing the vehicle motion is set up.The MODF model,which is 8DOF of four independent suspensions and four wheel tracks,is more applicable by comparison of its analysis result with some conventional vehicle models.Therefore,it is more suitable to use the 8DOF full-car model than a conventional 4DOF half-car model in the active control design for car vibration.Based on the derived 8DOF odel,a controller is designed by using LQ(linear quadratic)control theory,and the appropriate control scheme is selected by testing various performance indexes.Computer simulation 8is carried out for a passenger car running on a road with step disturbance and random road disturbance expressed by Power Spectral Density(PSD).Vibrations corresponding to ride comfort are derived under the foregoing road disturbances.The response results for uncontrolled and controlled system are compared.The response of vehicle vibration is greatly suppressed and quickly damped.which testifies the effect of the active suspenson.The results achieved for various controllers are compared to invesigate the influence of different control schemes on the control effect.     

染料中间体-腙类衍生物的合成

螺(口恶)嗪类光致变色化合物以高的光化学稳定性和抗疲劳性在功能材料等领域有着潜在的应用价值。普通的螺(口恶)嗪小分子在涂膜、成纤方面受到一定局限;而高分子材料在这些领域有明显优势,因此制备含螺(口恶)嗪基团的高分子材料具有重要的科研意义和实用价值。实验设计合成了一种新型可用于制备光致变色高分子的含双键的螺(口恶)嗪染料,本文报道了以苯肼和3-甲基-2-丁酮为原料合成染料中间体-腙类衍生物。     

The Jasper experiment: An exploration of issues in learning and instructional design

The Jasper Woodbury Problem Solving Series is an example of a video-based instructional macrocontext for complex problem generation and problem solving. The Jasper series and curricular materials are described and illustrated in this article. The theoretical framework underlying the series includes assumptions about educational goals and the nature of learning, including the importance of generative activities and cooperative learning situations. The authors argue that the Jasper series affords generative and cooperative learning activities in a way that traditional mathematics problem-solving materials do not. However, whether these features are utilized depends on the teaching model at work in the classroom. Three models of teaching—basics first, structured problem solving, and guided generation—that can be applied to the Jasper series are outlined. The strengths and weaknesses of each are discussed, and associated assessment issues are raised. The article concludes by pointing to the need for research on the impact of differing instructional design decisions.Members of the Cognition and Technology Group at Vanderbilt who contributed to this paper are Linda Barron, John Bransford, Olin Campbell, Ben Ferron, Laura Goin, Elizabeth Goldman, Susan Goldman, Ted Hasselbring, Allison Heath, Charles Kinzer, James Pellegrino, Kirsten Rewey, Robert Sherwood, Nancy Vye, Susan Warren, Susan Williams.     

中小学体育教师的自我认知对体育师资培养的启示

"新课标"颁布实施后,中小学体育课程改革不断深化,对体育教师也提出了新的、更高的要求。通过对一线体育教师的调查与访问,中小学体育教师在专业知识、组织能力、身心素质、体育专项技能和体育教学能力方面还有需要进一步提高和改善的方面。在体育师资培养过程中得到如下启示:将"新课标"纳入体育教育专业课程体系;强化体育基础理论知识,努力提高体育教育专业学生的文化水平;加强实践培养环节,使学生掌握现代的教学方法与手段以及体育活动的组织方法;加强现代化教学工具的学习与使用,突出专项技能。
