试论研究性学习课程及其生成

研究性学习课程是一种有别于传统课程的“生成性”课程。研究性学习课程生成就是在动态的过程中,不断产生新的课程内容。研究性学习课程生成要经过学生需要评估、拟定研究性学习课程目标、组织其课程材料、实施其课程方案、评价其课程方案等过程。研究性学习课程生成要受到政府政策、社区、家长、教育改革与教育科学研究、学校领导、教师、学生和学校的硬软件条件等因素的影响。     

一堂研究性学习课的设计与实践

研究性学习是一种自主学习、体验学习和探究学习的过程.数学研究性学习与其它基础性课程紧密配合,将更能发挥其培养学生探究能力之教育功效.     

研究性学习应回归生活

研究性学习课程不同于学科课程,是培养学生创造力发展,与生活紧密结合的一种新的课程形态.但是,由于研究的观念、现有评价和激励方式等方面的原因,使研究性学习课程在实施过程中容易远离生活,因此要进一步加强对研究性学习的理论认识,努力改变其教与学的方式,贴近学生的日常生活和生活经验,从而使研究生学习走向生活,回归生活.     

教师在"研究性学习"中的作用

研究性学习强调学生是学习的主体,要求学生在课程实施中自主地探究问题.这自然是研究性学习的特性,也是其课程价值所在.但是,强调学生自主,不是不要教师的指导,更不是教师可以撒手不管或对学生的课题研究不闻不问,而是教师依然要发挥其指导作用,并且这种指导应贯穿于研究性学习过程的始终,主要体现在:选题、研究方法、研究过程和成果总结等方面.     

开展研究性学习存在的问题

教育部制定的<普通高中"研究性学习"实施指南(试行)>颁布,使得研究性学习课程成为"综合社会实践活动"的核心课程.但由于研究性学习的课程形态、课程实施、课程评价等仍在探索阶段,在开设研究性学习课程的过程中难免存在这样或那样的问题,若不及时纠偏,很可能影响研究性学习的全面深入的开展.因此,有必要对目前研究性学习中出现的问题进行分析与探讨.     

研究性学习的问题研究与对策

研究性学习的开展对于培养学生能力与探究精神是非常有益的.但是由于研究性学习在实施过程中受到各种因素的影响,其实施过程存在诸多问题.应积极寻求改善的对策,使研究性学习课程这一新生事物不断完善,不断走向成熟.     

体育教学研究性学习的应用

研究性学习既是一种学习方式,也是一种课程形态,它有开放性、问题性、实践性、过程性、应用性、差异性等特点. 体育教学开展研究性学习需要有一定的组织实施方法. 体育教学研究性学习中应注意研究性学习课程与研究性学习方式的区别与联系,解决好学生主体作用与教师指导作用的关系,合理利用校内外课程资源. 研究性学习具有评价主体多元性、评价内容丰富性、评价方法多样性等特点.     

研究性学习课程是德育工作的新路径

几年来,我们在基础教育课程改革中,全面落实国家的课程设置计划,积极开设研究性学习课程,探索出德育工作的一条新路径. 一、成立组织--落实了主体德育 这里讲的"成立组织",不是指学校成立研究性学习课程的领导机构,而是指研究性学习课程的第一个环节,学生成立"研究性学习课题调研小组".调研小组组成过程,就是学生德育主体地位落实的过程,是学生自主、自觉参与德育活动的开始.     

数学研究性学习的探索与思考

目前,“研究性学习”课程已作为必修课正式开始实施了,要求各门学科都要渗透研究性学习的思想.研究性学习就是要让学生主动地参与研究过程,获得亲身体验,培养其良好的科学态度和学会进行科学研究的方法,研究性学习的素材可以是有定论的东西(如定理、公式)也可以是未知领域,答案可以不确定,可以丰富多彩,但提出的课题对学习必须有价值、有意义,符合学生实际.我曾对高中阶段开展“研究性学习”课程进行一些探究,现结合高中数学新教材教学中开展研究性学习的实践谈点己见,以供同行商榷.1对研究性学习的认识首先,研究性学习具有开放性、探究性和…     

研究性学习中德育价值的审视

近年来,要求课程与教学回归社会生活情境的呼声越来越高,研究性学习的开展是这种回归的真实写照.当我们强调研究性学习的理论、原则、方法、评价时,无形中却忽略了其存在的德育价值.本文将从研究性学习的目标、特点、模块、过程等视角来重新审视其所蕴含的德育功能,呼唤研究性学习中德育价值的回归.     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

汉字倒说

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?

Social and Cultural Influence on Word Meaning

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.     

Inequalities for inscribed simplexes

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex.
