教师、学生、数学教材和教学手段这四个因素是数学教学系统的基本因素,其中数学教材(包括教学大纲)是比较稳定的,而学生是在不断变化的(这不仅是学校的学生在更换,而且同一学生不同年龄有不同的认识能力)。教师要使教学遵循教学大纲并收到预期的效果,必须通过反馈信息.了解教学系统的 相似文献

要使教学系统成为一个可控制的系统,就要注意反馈信息。本文从教师对学生的反馈信息（信息主要来自课堂、作业和考察）、教师的自我反馈信息和学生的自我反馈信息三个方面,郑重阐述了在教学过程中,如何利用反馈信息及时纠正错误,提高教学质量的规律。 相似文献

数学课堂教学信息的处理杨莉数学教学系统是一个可控系统。数学课堂教学过程，是一个信息交流、加工、传递、矫正、调控、优化的过程、在这个过程中，教师要通过信息的及时反馈、阶段反馈、延时反馈，对教学及其形成性效果进行检验、修正、调整和优化，从而使数学教学系统... 相似文献

教学过程作为一个系统,由教师、学生、教材等诸多子系统组成,而连接各子系统之间相互作用的载体是信息的传递与反馈,它使教学过程处于不停顿的运动状态,从平衡到不平衡,再取得新的平衡,从而使教学系统不断地达到动态平衡。而作业的批 相似文献

教学反馈是教学系统有效发展的关键环节,是将教学过程中所产生的效果,作为新的信息再输入到教学过程中的一种互动过程.如果教师能有目的地进行教学反馈,可改进和优化教学,提高课堂教学的效率和教学质量.下面结合"异分母分数的加、减法"教学片断,谈一谈在小学数学课堂中的有效教学反馈. 相似文献

在教学的整个过程(或称系统)中,主要是反馈路线有两条:一条是学对教的反馈,即由学生的学习效果向教师显示反馈信息,教师准确地把握这一信息,调整教程,改进教法,从而实现对教的控制;另一条是教对学的反馈,即由教师根据学生的学习情况,发现学生存在的问题,向学生提供反馈信息,查漏补缺,长善救失并促使学生改进学法,提高学习效率,实现对学的控制。要提高教学系统的功效, 相似文献

小学数学课堂教学的调控,指在课堂上教师为获得最佳的教学效果,运用控制论的原理,根据学生的反馈信息,对教学内容、方法和过程等作必要、恰当、适时地调控。教学效果的优劣,在很大程度上取决于教师对教学活动的调控能力。探索教学系统的控制规律,按规律进行教学,是提高教学质量的必由之路。如何在教学活动中认识和运用这些规律,笔者认为,在教学过程中教师应优化组合各种调控方法。 相似文献

正化学教学系统是由教学内容、教师、学生及教学媒体诸多要素组成的一种复杂的组合体系。反馈系统是指控制系统把信息输送出去,然后把其作用的结果返回来,并对信息的再输出产生影响,起到控制作用。教学中的反馈是指师生在教与学的双向活动中的信息交流,是师生都作为反馈主体,向对方发出信息,彼此相互接受信息,并依次调节自己教和学行为的双向反馈。化学教学中的反馈形式有多种,根据反馈出现的时机,我认为一般可分为以下几种。 相似文献

用系统科学理论来考察教学系统,并指导其运作,可以使教学过程整体优化,达到令人满意的教学效果。 一、教学系统的要素及结构 按照系统工程观点,教学系统是整个教育系统中的一个复合子系统。该子系统可以看作是教师及其教授行为,学生及其学习行为、信息(包括学习内容、手段及媒体)、教学组织及环境等诸要素构成的一个复杂系统。在它的运作过程中、各个要素都在发挥作用,且是相互影响和相互制约与协调的。根据这一认识,我们可 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

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

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

This paper looks at the way drama works to bring a model of an arts curriculum into reality. He also shows how drama is valuable when discussed as a separate, autonomous subject in the school curriculum as opposed to one subsumed within English. He argues for a view of the arts and gives an example of a sequence of work in an English GCSE class based around Arthur Miller's play View from the Bridge. From this he draws out several strands about the relationship of the drama curriculum to the individual students and teachers, the school, and to culture. He also emphasises the primacy of performance in drama education. 相似文献
