高等几何课程中的数学思想

结合高等几何的教学实践 ,探讨了高等几何课程中的基本数学思想 .     

“初等几何研究”课程改革与实践

随着数学教育的深入发展，高师数学教育课程的势在必行。“初等几何研究”课程的教学大纲需要重新制订，其课程体系和教学内容也需要大幅度调整，特别是将原来的“初等几何研究”课程和“高等几何”课程合并成为一门课程，并将该课程的教学目的从初等几何“研究”转到初等几何教学素质的培养上来。与此同时，编写中的教材《初等几何教学基础》也必须突出与数学教育改革思路相适应的特色。     

基于建构主义理论的高等几何教学研究

分析高等几何课程的重要性及教学中存在的问题,运用建构主义学习理论,讨论高等几何课程的知识、思想方法建构、研究教学方法、教学手段在建构过程中的实际运用,并以典型案例介绍如何以学生为中心进行积极高效的高等几何建构教学。     

基于初等几何的高等几何的教学研究

高等几何课程是高等师范院校数学专业学生的必修课之一,长期以来学生总认为它对中学的几何教学没有任何帮助。本文从几个方面探讨了高等几何对初等几何学习的指导作用。     

《高等几何》课程教学的一点体会

本丈通过自己辅导、讲授《高等几何》课的教学实践,从论述《高等几何》(主要是“射影几何”)课程中包含的一些基本的数学思想及其在教学中的运用入手,对如何把握这门课程的主要内容、重点和难点,以利于取得较好的教学效果,提高教学质量谈了一点粗浅的认识和体会。     

高等代数与解析几何的教学实践与认识

几何为代数提供直观背景,代数为几何提供研究方法,文章论述了高等代数与解析几何课程一体化教学过程中的若干教学实践与认识。     

关于选择《高等几何》课程内容的看法

近几年来,全国师范大专院校,相继恢复了《高等几何》课程。其理由不外乎是:第一,扩充几何知识,为后继课和科学研究打基础;第二,《高等几何》的某些内容与中学几何教学联系密切,对高师学生毕业后进行中学几何教学有一定的指导意义。《高等几何》究竟包含哪些内容?其说不一。但比较集中的有两种看法:一是认为主要包含《几何基础》与《射影几     

高等几何在初等几何中的作用

高等几何是初等几何的延深课程.高等几何为初等几何的有关内容提供了理论依据,高等几何为初 等几何的某些问题提供了解题方法,高等几何可把初等几何的某些内容拓广与延深.     

高师数学专业开设高等几何课程的再思考

高等几何课是高等师范院校数学专业的一门重要的基础课.在数学教育专业的课程设置改革中将高等几何变成选修课甚至取消的做法对师范教育都是十分不利的.只要中学几何课不取消,高等师范院校数学专业就应该把高等几何课设置为必修课,这是由高等几何课自身的特点和其与初等几何知识之间联系的密切程度决定的,高等几何在中学几何教学中具有不可替代的指导作用.     

“初等几何研究”课程教学改革的实践与探索

随着基础教育课程改革的稳步推进和中学教师专业标准的出台,教师教育课程改革势在必行。“初等几何研究”是中学初等几何和高等几何课程的后续课程,是提升师范生几何教学能力的重要课程,其教学改革应立足于教学能力的提升改革课程目标,立足于接轨改革教学内容,立足于实践参与改革教学方法,立足于过程建立多元化评价模式,体现教学的拓展性、接轨性、专题性、研究性、实践性特点。

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

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.
