1引言新的物理课程把科学探究作为学生的学习目标和主要学习方式,要求学生经历和体验科学探究的过程,以提高探究能力、培养探究精神.我们物理教师要深刻理解科学探究的意义,同时还要具备在物理实验中实施探究式教学的能力.下面是笔者实施的一个探究性学习活动,希望能对物理教师 相似文献

探究性学习是新课程大力提倡的一种学习方式,课堂实验探究又是探究性学习的一种重要形式.课堂实验探究由于时间、空间的限制而具有自己的特点,对探究的设计也有具体的要求.只有明白这些要求,才能更好的实施探究性学习和探究性教学. 相似文献

探究性学习方式最终要实现的目标是使学生在探究性学习过程中形成探究能力,学生只有形成探究能力,才能在今后脱离课堂、脱离老师的情况下独立学习,才能受益终生. 相似文献

《生物课程标准》提出了"面向全体学生,提高生物科学素养,倡导探究性学习"的课程理念,力图促进学生学习方式的转变,引导学生自主探究,培养他们的动手能力,尤其是创新精神和实践能力的培养。而中学生物实验正是提高学生生物科学素养,提高学生探究能力最直接、最有效的方法之一。但是,现阶 相似文献

新课程强调的科学探究是一种有效的学习方式。科学探究对发展学生的科学素养具有不可替代的作用。那么,化学课堂教学中如何实施有效探究呢？下面,我结合自己的教学实践提出一些探究性实验教学的思考。
探究性实验教学一般的教学模式是：诱导准备——实验探究——归纳研究。这三个阶段是探究性学生实验的具体实施过程。下面我结合化学教学,分别加以概述。 相似文献

探究性学习是学生从问题或任务出发,通过形式多样的探究活动,以获得知识和技能、发展能力、培养情感体验为目的的学习方式.探究性学习的方法是灵活多样的,既有实验的方法,也有观察、调查或测量的方法,这要根据探究的课题来确定.近年来,我们从化学实验入手,把化学探究性实验作为发展学生探究能力的重要途径,在化学教学过程中进行了反复的尝试与实践. 相似文献

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? 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
