优化教学策略 推进素质教育

本文从认知科学的角度，探讨优化小学数学教学策略。包括１．优化激起认知动因的策略；２．优化呈示认知内容的策略；３．优化渗透认知方法的策略；４．优化评价认知结果的策略。     

认知负荷理论观照下的高等数学信息化教学

认知负荷理论是基于人类认知的信息加工理论.在认知负荷理论指导下进行教学设计,能够增加学生的有效认知负荷.现代科学技术的发展、丰富的教育教学资源是高等数学信息化教学的存在条件.合理运用现代教育技术,能够"减负增效".运用信息技术优化课堂教学可以采取以下策略:选择恰当时机,采用片断式课件;遵循简单原则,整合多种教学手段;使...     

运用认知心理学原理,优化新课标下物理学习的策略

本文从认知心理学的角度分析中学生物理课学困生的原因,并根据认知心理学理论和物理学科的特点提出相应的优化策略,从而达到完善认知结构,实现新课程要求的三维教学目标.     

调节心向策略在数学教学中的应用

在教学心理学研究中 ,人们往往习惯于从认知维度探索教材的优化处理策略 ,而对情感维度上的研究则相对薄弱 .美国当代著名教育心理学家奥苏伯尔曾针对“讲授教学”提出了意义学习的两个先决条件 :一是学习者有同化新材料的认知结构 ;二是学习者有意义学习的心向 .虽然注意到了认知、情感维度对学习的交互作用 ,但他本人也仅从影响学生认知结构的角度 ,提出教材的认知处理策略———先行组织者策略 ,而未从影响学生心向的角度 ,提出教材的情感处理策略 .事实上 ,这两个维度上的探索分别涉及学生对教材的可接受性和乐接受性问题 ,是从整体上提…     

优化教学设计 提高教学实效

基于认知负荷的相关理论,从以下几个方面:1.设定合理的课堂容量,让学生满负荷学习;2.多种呈现方式相互补充,调动多种感官;3.多用口头的解释文本和视觉信息;4.变式教学促进相关认知负荷,促进学习的有效迁移等几个方面提出策略,优化教学设计,以提高教学的实效。     

基于建构主义的教学策略探析

教学策略是现代教学论研究的新课题。基于建构主义的教学策略就是以促进学生建构良好的认知结构为主要目的的策略,其策略体系包括优化原有认知结构的策略、引发学生认知冲突的策略、教会学生认知加工方法的策略等。     

实施课程改革,必须改进教育策略

实施课程改革,必须改进教育策略.教育策略有:激起认知动因的策略,组织认知内容的策略,安排认知方法的策略,利用认知结果的策略.     

让学生在反思中形成策略——例谈“解决问题的策略”一课教学

<正>元认知理论认为:"反思是学生对自己认知过程、认知结果的监控和体会;数学的理解要靠学生自己的领悟才能获得,而领悟又靠对思维过程的不断反思才能达到。"所以,学生知识的获得离不开反思,通过反思可以深化学生对策略的理解,优化策略选择,揭示策略的本质;通过反思     

对概念形成教学中认知材料的认识与思考

小学生的认知特点决定了概念形成成为小学数学概念的主要构建方式.而概念形成的认知规律义决定了认知材料成为概念教学的本源和基础.为此,概念的有效形成必须建立在对认知材料作出深入分析的基础之上,如.认知材料有哪些类别.如何适时适度并以适宜的方式对认知材料加以提供和择用.认知材料在概念形成中有哪些支持性策略等.这些都是优化概念教学的重要视角与有效依托.     

英语听力教学方法浅探

<正>英语教学要求学生掌握听、说、读、写四种能力,其中,听力位丁各能力之首,在高考中的地位显而易见,一直是英语教学中的重要环节。笔者针对目前中学生在英语听力方面存在的若干问题,探索出一些提高英语听力教学效率的策略。在听力教学中,围绕"会听"和"听懂"优化教学策略,更体现课程的教学要求。优化听力教学策略,应注重如下方面:强化语言认知过程,增强认知体验;注重听学技巧,提升理解能力;突出认知思维深化,形成有效策略;模拟情境环境,刺激学生感官。

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?     

只要努力,不要后悔

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.     

浅谈移民问题

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.     

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.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
