“数列单调性”研究型单元教学设计

研究型单元教学的核心理念是学习即研究,教学即研究指导;其基本教学模式是“五环十步”^[1]——呈现背景、提出问题,联想激活、寻求方法,提出猜想、验证猜想,运用巩固、内化迁移,回顾反思、拓展问题;其基本做法是以单元为单位进行教学要素分析和教学设计。本文以“数列单调性”为单位进行大背景、大观念、大任务引领下的小单元教学。     

浅议学生数学猜想和直觉能力的培养

<正>近期阅读了张蕴禄老师的一篇文章,文章主要围绕如何培养学生的猜想和直觉能力这一十分重要的问题,提出了一个与传统观点相悖的观点:"能否少问学生几个‘为什么’".本文就上面的问题结合笔者在自身教学工作中的一些实践,对高中数学教学中如何培养学生的数学猜想和直觉能力谈谈自己

研究型教学——高校思想政治理论课程研究与实践新动向

近年来学界对高校思想政治理论课程如何开展研究型教学问题逐日关注,呈现出一些值得透视的研究新动向,主要是:研究型教学概念的提出与诠释;聚焦高校思想政治理论课推进研究型教学面临的问题与挑战;高校思想政治理论课程实施研究型教学的对策与建议;旨在提升实施研究型教学的教师素养、构建研究型教学评价体系,提高高校思想政治理论课程教学的实效性。     

开展思想政治理论课研究型教学的意义和实践路径

一思想政治理论课研究型教学的内涵自从2005年教育部《关于进一步加强高等学校本科教学工作的若干意见》提出"要积极推动研究性教学,提高大学生的创新能力"以来,研究型教学开始在我国各高等院校受到重视并得到逐步推广、尤其是在研究型大学更是流行。研究型教学也被称作探究法教学或发现法教学,作为一种新型的教学理念,它更加注重积极发挥教师的主导作用及教师与学生的"双主体"作用。这种教学法在西方早已得到广泛采用,尤其是在自然科学学科的教学方面。美国芝加哥大学施瓦布教授认为,研究型教学"是指这样一种学习活动:学生通过自主地参与知识的获得过程,掌握研究自然所必需的探究能力;同时,形成认识自然的基础——科学概念;进而培养探索世界的积极态度"。我国也有许多学者探讨了研究型教学的科学内涵。有学者指出:研究型教学是教师与学生共同探索获得知识的过程,也是他们围绕问题共同展开对内容的确定、方     

数学课堂 将猜想进行到底

猜想是数字理论知识发展中最积极、最活跃的因素,是它推动着数学不断前进。在高中数学课堂,教育者应鼓励学生大胆猜想,在猜想中实现学生理性思考与直觉推断的完美融合。本文结合高中数学教学实践,对如何引导学生科学猜想进行了全面探析。     

高中数学数列教学设计的实践探讨

在高中数学课程内容中,数列作为离散函数的典型代表之一,不仅在高中数学中具有重要位置,而且在现实生活中有着非常广泛的作用,同时,数列的教学也是培养观察、分析、归纳、猜想、逻辑推理以及运用数学知识提出问题、分析问题和解决问题的必不可少的重要途径.

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.
