为进一步思考数学理解的基本含义,寻求整合相关研究与教学的新理念,文章首先从知识观、学习观和研究思想三方面分析情境认知与学习理论同传统学习理论的差异,在此基础上从研究思想与定位、对象与目的、内涵、形成机制、条件和方法等对数学理解的已有研究进行反思与质疑,指出进一步研究应该采纳新的研究思想、重新定位数学理解,转变知识观、树立数学理解新目标,拓展数学理解内涵,重构教学理解的形成机制,系统分析并构建有效的数学理解环境.  相似文献

情境学习理论认为,学习的实质是个体参与实践,与他人、环境等相互作用的过程,是形成参与实践活动的能力、提高社会化水平的过程.学习更多的是发生在社会环境中的一种活动.基于情境学习理论的中学概率教学的策略主要有: "数学现实"、情境体验与建模、合作学习和注重现代信息技术运用.  相似文献

学习理论发展的情境脉络   总被引:1,自引:0,他引:1  
目前学习理论存在三大派别:行为主义、信息加工理论与情境认知。在学习理论发展中存在着关注情境的共性,三类学习理论对于情境的认识是不断发展的连续统一体。为此,在教育教学中我们应当正确认识各个理论的优势,理性看待情境创设的适用性,尤其在研究性学习的设计与实践过程中。  相似文献

20世纪90年代初,情境认知理论在西方开始盛行.约翰·杜威(John Dewey)曾指出“思维源于直接经验的情境”,在我国,对情境教学的研究可追溯到李吉林老师的情境教学法实验,贵州师大吕传汉和汪秉彝教授于2001年开始“数学情境与提出问题”的课题研究,成果颇丰.所谓情境教学,是指运用具体活动的场景或提供学习资源以激起学习者主动学习兴趣、提高学习效率的一种教学方法情境教学的理论基础有认识论、学习论、现代教学观、现代心理学及数学文化.  相似文献

正所谓研究性教学是以教师指导学生主动探索、实践和交流为主要学习方式的教学活动。研究性教学以培养学生创新能力为指导,以建构主义理论、合作学习理论等为理论依据,坚持从学生实际出发,充分调动学习的积极性,使学生在学习中感受数学的魅力。笔者以为,在具体实施中,可以从以下几方面着手:一、创设问题情境,激发学习兴趣1.利用数学与实际问题的联系创设问题情境。生活离不开数学,数学也离不开生活。研究表明,当数  相似文献

很好地落实或体现新的学习理论或观念,是当前数学教育工作所面临的一个紧迫任务。新的课程改革要求培养学生创造能力、动手能力,在学习过程中体验、感受知识发生发展的过程,以及对知识的进一步拓展。这就要求教师对教学过程进行设计,以指导学生克服多年的“应试教育”所带来的消极影响,尽快地完成从知识的继承者到知识的创造者的转变。教师在工作中要关注这样几个方面:学习情境的设计,合作学习与学习共同体,活动与内化,理论与教学实践,以及对传统教学的再认识。而这其中,以情境的设计与学生的学习活动的控制尤为关键。陶行知先生说:“发明千千万万,起点是一问”。  相似文献

《普通高中数学课程标准(实验)》提出:“数学教学中,教师要创设适当的问题情境.鼓励学生发现数学的规律和问题解决的途径,使他们经历知识形成的过程。”奥苏泊尔的有意义学习理论认为:创设一定的问题情境,能够使学生对知识本身发生兴趣,进而产生认识需要。产生一种要学习的倾向,从而能够激发学生的学习动机。因此,在实际教学中.创设怎样的数学问题情境更有利于学生的学习,无疑成为广大教师关注的热点。我结合多年的教学经历及尝试,总结了以下几种做法。  相似文献

在小学数学教学中.教师要转变学生的学习方式,为学生的主动探索与发现提供空间与机会,让学生能主动地面对问题情境,让他们真正经历主动的假设、积极的探究、努力的尝试、及时的反思与修正等学习过程,进而在数学课堂教学中实现师生、生生互动,达到双方互动共享.下面,笔者结合教学实践,谈几点肤浅的认识与体会.  相似文献

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.  相似文献

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。  相似文献

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.  相似文献

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?  相似文献

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.  相似文献

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.  相似文献
