promotion of employment, form a reasonable and orderly pattern of income distribution, build a more fair and sustainable social security systems, medical and health system reform. The plenary, innovation of social governance, must focus on the maintenance of fundamental interests of the overwhelming majority of the people, maximize factors, enhance social development, improving social governance, the interests of national security, ensure that the people live and work, social stability and order. o improve social governance, stimulating social organization, innovative and effective system of preventing and resolving social conflicts, improving the public security system, set up the National Security Council, national security systems and national security strategy to ensure national security. Plenary session, the construction of ecological civilization, you must establish systems of ecological system, using the system to protect the ecological environment. To improve natural resources asset property right system and use control, red line of delimitation of ecological protection, resources paid use system and ecological compensation system in ecological environment protection management system reform. Plenary session, centering on building a listening party command, can win and having a fine style of the people's army, a strong army under the new situation of the party Goals, restricting the development of national defense and army building is solved outstanding contradictions and problems, innovation and development of military theory, enhance military strategic guidance, improve the military strategy in thenew period, building a modern military force system with Chinese characteristics. To deepen the adjustment of personnel system reform in the army, military policy and system reform, promote the development of military and civilian integration depth. Plenary session stressed that comprehensive reform must be to strengthen and improve the party's leadership, give full play to the core role of the party commands the overall situation and coordinating all parties, improving the party's leading water ... Margin. Challenged the leadership of the Communist Party of China, Marxism-Leninism and Mao Zedong thought by Deng Xiao-ping's flag, replaced by three representatives and the harmonic society. The former Communist Party spirit and social cohesion point of almost all political makeover. Characteristics of socialism public ownership is shifting to private ownership, planned regulation and market regulation, the proletarian regime controlled by the elite. Of universal equality, fairness and basic principles of distribution system is socialist society, however after economic monopolized by powerful, vested interests grow, employers do not have the same status, hardly seems fair social distribution. State key protection of capital interests rather than the interests of citizens, had been hits the bottom of the proletariat五年级数学上册《可能性》教学反思

万丰镇中心小学 张海兰

可能性是学习数学四个领域中“统计与概率”中的一部分，“统计与概率”中的统计初步知识学生在之前的学习已经涉及，但概率知识对于学生而言还是一个全新的概念，它是学生以后学习有关知识的基础。本单元主要教学内容是事件发生的不确定性和可能性，并能知道事件发生的可能性是有大小的。教学关键是如何让学生把对“随机现象”的丰富的感性认识升华到理性认识。

五年级学生已经具备了一定的生活经验和统计知识，对现实生活中的确定现象和不确定现象已经有了初步的了解，并有一定的简单分析和判断能力，但学生只是初步的感知这种不确定事件，对具体的概念还没有深入地理解和运用。根据学生的年龄特点和生活经验，教师做出适当引导，学生就会进行正确的分析和判断的。所以教材选用学生熟悉的现实情境引入学习内容，设计了多种不同层次的、有趣的活动和游戏，激发了学生的学习兴趣，使其感受到数学就在自己的身边，体会数学学习与现实的联系，为学生自主探索、合作学习创造机会。

在本单元的教学中，我做了充分的准备，使用了尽可能自制的教具，在教学中引起了学生极大的积极性，让全班同学都有乐于地参与到学习活动中，意图让学生在具体的操作活动中进行独立思考，使学生在大量观察、猜测、试验与交流的过程中，经历知识的形成过程，逐步丰富对不确定现象及可能性大小的体验。

在这样的教学活动中，基本实现了教学目标。让使学生初步体验有些事件的发生是确定的，有些事件的发生是不确定的。能列出简单试验所有可能发生的结果，知道事件发生的可能性的大小。能由一些简单事件发生的可能性大小逆推比较事件多少。学生感受到生活中处处有数学，并能够运用可能性的知识解决生活中的问题，逐渐对统计与可能性知识产生兴趣，培养学生学习数学的兴趣。也抓住了教学重点。让大部分学生会用“可能”“不可能”“一定”描述事件发生的可能性。能够列出简单试验中所有可能发生的结果，知道可能性是有大小的。

但也有不足之处，例如部分学生仍然不能正确理解并会“可能”“不可能”“一定”描述事件发生的可能性。而且在描述可能性，判断公平性，特别是设计公平游戏规则等方面仍有不少困难，这需要加强训练来提高学生的逻辑判断以及精确地表达自己的思想。

bviously, face China's Socialist system, the Communist Party is not the party. In that case, political chaos has been very tight. Is remodeling or reconstruction, is a correction or a stove. Whether to turn right or left, is back to the source or put forward new political ideas. This is to determine the road problems in China, is also the key out of the deep water of the reform of the economic system. After 18, the new Central collective leadership attaches great importance to political orientation. First, the \articles\point, starting from the Central Government's self-restraint, which preaches and pro-image, brought fresh feeling to the community. Secondly, before reform and opening up and reform and opening two periods after non-negative, untying the tangle of thesociety a long time on this issue. Third, a new generation of party leaders on various occasions to Mao Ze-Dong and Mao Ze-Dong's thought of evaluation has room for mnoeuvre, through to the ruling ideology of Mao Zedong thought, is the call of the soul to the Socialist Revolution and construction. Empty talks jeopardize national interests and try again, is an affirmation of Deng Xiao-ping's reform ideas. These strong political signal showing a new generation of political leaders is still keeping to the Socialist road. Four is revisiting the \ng to Mao Ze-Dong's historical cycle of\ofile anti-corruption and the importance of the Constitution, reorganization is bad style of officialdom, was to civilize people obey the law, while improving the color change of the regime of vigilance. Five is to reform into deeper waters and stressed that top-level design, this is a review on the reform and opening up in the past, is also looking for a way out. Six foreign and Russia closer, the flexible attitude on the issue of the Korean peninsula, Sino-Japanese fishing hardline China on the island out of the \nt\ow profile shadow began to gradually plan development. Signs show that the new leadership began to make a left turn in politics. However, as of right nownot only ideological confusion in the community, the new leadership's thinking is messy. New leaders both stressed the need to implement the Constitution, stressed the need to turn off the power in a cage. Also stresses that Mao Zedong thought cannot be lost, 30 years after the reform and opening up 30 years ago can not deny each other. Both advocate democracy and release \does not speak of\her deny the history of the CPC Central Committee on several issues ...Comrades: today brings together members, mainly in order to provide a platform to Exchange and learn from each other in order to facilitate our work. Just now, we focus on taxation, planning and stability, safety, project construction, typical topics such as private facts presentation and interaction, and towns currently exist in the in-depth analysis of the problems to be solved, to explore new methods to solve the problem. It can be said that summing up the achievement, no grandstanding; analysis
