问题探究的方法是多种多样的,但主要是程序性探究与随机性探究。程序性探究即教师在课堂上组织学生对既定问题进行探究。这种方法讲究师生共同参与,形式活泼、行之有效,深得师生青睐。但是既定问题大多出自教师,有时难免偏离学生实际,学生一时没有兴趣探究,最后落得个教师自导自演、自问自答。要避免这种尴尬,必须重视对随机性问题的探究。所谓随机性问题,即学生在学习过程中即兴提出的有探究价值的问题。教师根据教学需要,择其要者组织学生进行探究.这就是随机性探究。  相似文献

综合实践活动课程强调学生通过实践增强探究和创新意识、学习科学研究的方法、发展综合运用知识的能力。在教学中,教师与学生处于相互反思关系之中,教师不特别要求学生接受教师的权威,相反,要求学生延缓对教师权威的不信任。强调学生与教师共同参与探究,探究那些学生所正在体验的一切。  相似文献

教师作为探究式课堂教学的导师,其任务是调动学生的积极性,促使他们自己去获取知识、发展能力,做到自己能发现问题、提出问题、分析问题、解决问题。与此同时,教师还要为学生的学习设置探究的情境,建立探究的氛围,促进探究的开展,把握探究的深度,评价探究的成败。  相似文献

数学探究是指学生围绕某个数学问题,自主探究、学习的过程。它是研究性学习方式之一,有利于学生形成积极主动.勇于探索的学习品格。数学探究课题选择是完成探究学习的关键,如何创造数学探究课题已成为教师重要的教学活动。教师要成为学生进行数学探究的组织者、指导者、合作者、评价者。  相似文献

在新课程背景下,自主探究的教学理念进入了数学课堂,已为广大教师所认同并在积极实践中。与此同时,有的教师却排斥、冷落了教师的“讲解”,片面地崇尚学生探究,在课堂上滥兴探究之风。请看如下教学案例。  相似文献

“自主—探究”式课堂物理教学,实质上是将科学研究领域的探究方法引入课堂,使学生通过类似科学家的探究过程理解科学探究的本质,培养科学探究能力。在“自主—探究”教学模式中,教师是组织、引导的主体,学生是探究、学习的主体。教师充分挖掘物理教材中的各种有利因素,在教师的启发、诱导下,通过学生的亲自参与和探究活动,由学生主动去发现概念、规律。在这种形式的学习过程中,学生不仅学到了知识,更重要的是学到了获得知识的过程与方法。这样做培养了学生的主体意识、科学探究能力、实事求是的科学态度和敢于创新的探索精神。  相似文献

《科学(7∽9年级)课程标准》中,提出了“科学的核心是探究”、“突出科学探究的学习方式”等新的理念。在探究教学中,教师对学生的引导是必不可少的,教师引导策略的合理与否会直接影响到探究效益的高低。现结合浙教版《科学》教学的体会,谈谈在《科学》探究教学中教师的引导策略。  相似文献

国外探究教学教师因素的研究概述   总被引:1,自引:0,他引:1  
影响探究教学实施的因素有很多,但从教师的角度分析教师因素,比如教师的知识、看法等对探究教学实施的影响的研究较少。文章就目前国外对这一方面的研究现状作了总结与评述,以期对我国探究教学的研究提供方向和新的视野。  相似文献

随着新课程改革的不断推进,探究式学习作为科学课学习的一种基本学习方式,已被越来越多的教师实践着。但是,学生一旦离开教师这个“拐杖”,自主探究某一问题时,却感到无从下手,不知如何进行研究。因此,教师要从根本上转变教学观念,引导学生像从事科学研究那样去观察、实验、思考,从而培养学生自主探究的精神,树立自主探究的信心,增强自主探究的能力。[第一段]  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

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

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.  相似文献
