化学启发式教学模式实验研究

通过对化学启发式教学模式教育理论和教学原理的研究，构建激发学生自主探探索的化学启发式教学模式，是化学教学改革实施素质教育的重要手段和突破口。     

结构主义教学模式初探

化学教学模式，是指在一定教学思想指导卞，围绕化学教学活动中的某一主题所形成的相对稳定，系统化和理论化的教学模式，是构成化学课程、选择化学教材和提出教学活动的一种规范格式。     

化学教学模式的演变与发展

教学模式是美国学乔伊斯(B．Joyce)和韦尔(W．Weil)于20世纪70年代首先提出来的一种贴近教学实际的理论模式，它能为教师的教学实践活动提供指导和预见，成为教学论研究的热点之一．国内的教学论专家随即开展了相应的研究，与此同时，化学教育工作也结合教学实践，或从化学课型的角度提出教学模式，或从国内化学教学活动中归纳整理而成教学模式，又或从现代教学理论的领悟中演绎教学模式．教学模式不断发展变化，多样化、理论化、综合化是当前化学教学模式变化的主要趁势．     

高中化学网络教学模式的构建

构建网络技术环境下的化学教学模式是现代化学教学面临的新挑战，本文首先提出了网络技术环境下化学教学的七种模式、筒述了各教学模式的理论依据、基本特征和过程，最后分析我们在教学过程中的一些实际教学案例，总结我们在高中化学网络教学中的一些探索。     

多媒体辅助化学教学面面谈

多媒体应用于化学教学可提高教学效率，有利于因材施教，扩大化学教育的范围。可根据教学需要，应用不同的教学模式，并按照教学原则设计化学教学多媒体软件。     

新课程标准体系下化学教学模式探究——协商化学教学模式构建初探

本剖析了传统化学教学模式片面强调学科知识和技能培养、由教师单一向学生传统输知识的弊端，依据新化学课程标准对教学的要求，构建了师生平等对话、互动协作、共同探究的化学教学模式。     

谈目教学模式在化学教学中的应用

章对目标教学模式在化学教学中的应用进行了研究，并结合《葡萄糖》一节的教学，具体说明了“三步六环节”教学模式的操作程序。     

实验探究教学模式

近两年，化学探究式教学过程的构建在中学化学教学领域颇受人们关注，许多中学化学教师在这方面做了一些有益的尝试，下面是我对化学实验探究教学模式的一些概括。     

化学网络教学模式的研究

构建网络技术环境下的化学教学模式是现代化教学面临着的新挑战，本文首先提出了网络技术环境下化学教学的七种模式，简述了教学模式的理论依据、基本特征和过程，最后分析在教学过程中的一些实际教学案例。总结在高中化学网络教学中的一些探索。     

支架式探究性化学实验教学的构建策略

支架式教学是通过提供一套恰当的概念框架来帮助学生理解特定知识、构建知识意义的教学模式。该教学模式在教学方式上与探究性实验教学具有相容性。运用支架式教学模式构建探究性化学实验教学的基本环节是：进入化学实验问题情境；搭建实验支架，引导探究；独立探究化学实验；协作探究化学实验：实验探究的效果评价。

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.
