论教学理论介入教学实践的路径与价值

教学理论与教学实践脱离之根本在于教学理论工作者与教学实践工作者之间的隔阂。破解教学理论与教学实践的"两张皮"难题,需要教学理论工作者与教学实践工作者的团结协作。站在教学论学科立场上看,教学理论必须从关注教学实践走向介入教学实践。教学理论要介入教学实践的根本原因在于教学论学科所具有的双重性格,即教学论既具有理论性,又具有实践性。教学理论介入教学实践有四种基本的方式与途径:一是教学理论工作者将教学理论带入教学实践;二是教学实践工作者到教学理论工作者那里"取经";三是在区域性的教育实验中教学理论工作者与教学实践工作者的合作;四是国家宏观教育改革过程中教学理论工作者与教学实践工作者的合作。教学理论介入教学实践的价值在于发展教学理论,有效推进教学实践。     

高中生物新课改呼唤优质教学

新课程呼唤有效教学和优质教学,有效教学是对教学的基本要求,优质教学是追求的目标;有效教学未必是优质教学,而优质教学必然是有效教学,优质教学是更高层次的有效教学。在高中生物教学中,课程改革的理念是优质教学出发点和归宿点;提高学生生物科学素养是优质教学的根本目标;课程三维目标是优质教学的导向点和评价点。     

教学想象的审美阐释及提升策略

教学想象是课堂教学中一项蕴含艺术性的活动,富有想象的教学过程会促成教学美。教学想象中蕴含的美是基于教学构成性美的综合考量,包括要素、过程、形式与风格的美;它是指向教学生成性美的全面激发,表现在教学动态生成与发展中。教学想象之美表现为:借助教学想象达成教学目标的优化;依托教学想象实现教学内容的活化;凭借教学想象彰显教学主体的互动;依仗教学想象呈现教学过程的创生。为构建教学想象美化教学,需通过教学想象之外制定适切的教学目标,实现教学形式美;教学想象之内使教学内容充满活力,确保教学内容美;批判已有教学想象给师生留有深度想象的自由,达成教学过程美;教学想象之上充实教学活动,提高教学审美的品位。     

基于教学目标的有效教学策略

有效教学是对中小学落实课程标准的要求,也是对教师具体教学行为的要求。所以说,教学是否有效,关键在教师。目前,很多教师对有效教学的理解存在偏差,对有效教学与教学目标之间的关系认识模糊,导致教学随意化、去目标化等现象的发生,影响了教学的效果。基于教学目标实施教学是实现有效教学的重要途径,主要策略有：理清教学目标与课程标准、教科书之间的关系,确定教学目标;科学选择和组织教学内容,有效承载教学目标;分析学情,为有效达成教学目标奠定基础;以教学目标统领教学过程,有效达成教学目标;基于教学目标进行教学评价,保证教学目标的有效达成。     

高师院校数学与应用数学专业的教学改革——以高中新课程为视角

目前,我国高等师范院校教学与应用教学专业的教学存在学生的教学观和教学教学观落后、教学专业理论基础薄弱、教学内容陈旧、教学手段落后、教学评价单一等问题。高中教学新课程实施给我国高等师范院校教学与应用教学专业的教学带来了挑战。为此,必须树立先进的教学观和教学教学观;全面修订教学与应用教学专业的培养计划;制定合理的教学教学目标;改革教学教学内容;改变传统的教学模式;革新教学手段;突出师范性;重视学生科研能力的培养。     

教学创新再探寻——基于教学习惯的视角

未来社会的竞争是创新性人才的竞争,这需要教学创新予以支持.受传统文化、思维定势、教学权威、安逸的教学生活形成的教学习惯影响,当前教学中普遍缺乏创新.突破教学习惯的禁锢,实现教学创新,需要教学视野的开放、教学思维的变革、教学问题的诘问、教学理性的充盈、教学自主的萌生,克服教学习惯的束缚,实现教学创新.     

论教师教学惯习的强化与变革

教学惯习是对教学要素结构化的产物,教学惯习对教学要素的吸纳、粘滞和锁定,形成了教学惯习的自我强化机制,使教学机智所需的教学要素被阻断。教师要对被教学惯习吸纳的教学要素施行变革,让教学要素重新流动起来,这种变革的动力来源于未被教学惯习吸纳的唯一教学要素也是最重要的教学要素——学生。让所有的教学要素回归到学生主体上,使学生来聚合所有的教学要素,这样,被吸纳的教学要素才能重新在师生中流动开来。     

侧面教学的缘起、特征、案例及实质

在正面教学、正规教学、有计划教学大行其道的当下,侧面教学、非正规教学、无意识教学易被人所忽略,但它在现实生活中又确实存在,并发挥其独特的作用.提出侧面教学,是因为正规教学存在局限性,而侧面教学潜力巨大,不为一般人所注意,且侧面教学与正规教学本是一个整体.侧面教学的形式与内容呈现境遇性、生活化和社会化的倾向;侧面教学具有即兴教学、个别交流、心灵对话的特点.侧面教学的实质在于:它是教师综合素养的投射,是对学生沉睡心灵的唤醒,是正规教学质的飞跃的催化剂.侧面教学不是正规教学的对立面,侧面教学并非随意教学,侧面教学不等于非制度化教育,侧面教学不等于非课堂教学,侧面教学不等于课外辅导,从事侧面教学的并非都是正规教师.     

教学细节范畴论：概念、本质与特征

＂教学细节＂是一个理应得到重视的教学范畴。教学细节指的是学校教学过程中发生的、对教学具有一定影响的最基本的教学要素或教学行为。本质上看,教学细节是一种微型教学事件。把教学细节视为微型教学事件,有助于重视、提高教学细节在教学中的作用,增强教学细节设计意识;有助于用联系的观点看问题,在教学过程的整体中研究、优化教学细节。教学细节具有指示性、微型化、生成性和情境性特征。     

教学限度：一个需要探究的话题

所谓教学限度,是指教学思想、教学方法、教学手段、教学目标、教学效果等与教学有关的内容或要素,在教学实施中,具有适用性、有限性、局限性。教师在教学过程中不要超越教学限度,要有效地控制教学要素的容量、进展,实现教学要素的有机组合,以取得最优化的教学效果。教学限度不是某个具体的数值,而是一种临界的状态。与教学限度相对的概念是教学过度或教学无度。

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?     

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.     

只要努力,不要后悔

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.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
