“双基”是我国数学教育的优良传统，在新形势下，它需要不断地“与时俱进”，并保持合理的内核，形成科学的、符合学生实际的“数学新双基”．为准确地把握数学教育中的“双基”，对数学“双基”中的形式化与非形式化问题进行深入的探讨就显得十分必要．为此，浙江师范大学课程与教学论(数学)专业的几位同仁在导师张维忠教授的指导下，围绕“数学‘双基’中的形式化与非形式化”主题展开了一次深入讨论，以下是大家发言的主要内容。 相似文献

注重“双基”教学是中国数学教育的传统。偏面地注重“双基”教学导致中国学生在解决实际问题能力、思维能力及对数学的情感、态度等方面没有得到应有的提高与发展。因此，“双基”内涵的扩充、教学方式的改变及教学观念的转变等就成为改变“双基”教学现状的关键。 相似文献

一、数学“双基”的新内涵数学双基(指基本知识和基本技能)是我国数学教育的优良传统,它充当着培养学生数学能力、个性心理品质与进行思想教育的载体.数学“双基”不仅是学生继续学习数学,向更高的数学能力发展的基础;而且也是学生学习其它知识,形成其它能力所必备的基础.数学“双基”教学与能力发展息息相关,离开了它能力发展就无从谈起.在实际教学中,有不少学生由于忽略了基础知识的学习及基本技能的训练,而影响了其它知识的学习与基本技能的形成,同时制约了能力的提升.当然“双基”教学若离开了能力培养,也就无的放矢.我国20世纪60年代已基本形成“抓好双基,培养三大能力”的特点, 相似文献

注重“双基”教学是中国数学教育的一个特点和优点。“双基”教学也暴露出“基础过剩,创造力不足”的缺点,阻碍了学生在解决实际问题能力、思维能力以及对数学的情感、态度、价值观方面的发展。在新课程改革的大环境下,如何继续发挥“双基”教学的特色又能消除它的不足之处,促进“双基”教学与新课标理念的有机整合是关键。这就涉及如何重新看待“双基”的内涵.如何调整教学方式以及相应的教学观念。 相似文献

中国数学教学中的"双基"和开放题问题解决 总被引：4，自引：0，他引：4
“数学双基教学”的含义是:“在掌握基本知识和基本技能的基础上,谋求学生的发展。它在教育学上主张:运算速度:速度导致效率;程序记忆:记忆通向理解;精确表示:逻辑保证精确,练习操作:重复依靠变式。“数学双基教学”的特征是,教师掌握课堂教学的节奏,精讲多练,强调逻辑表示,注重数学思想方法。“数学双基教学”的文化背景包括:精耕细作的稻作文化;严厉选拔的考试文化,熟能生巧的教育古训,最后是20世纪50年代来自前苏联的教育影响。过去的10年,双基数学教学有了一些变化。中国的数学教育家正在寻求东西方数学教育理念之间的平衡。开放题教学是加快“双基数学教学”进步的有效途径。 相似文献

我国的数学“双基”教学有着一定的优越性，但随着社会经济和技术的发展，随着数学理念的发展，新的数学课程在设置和实施方面都在重新审视基础知识、基本技能和基本能力的具体含义与内容．另一方面，重视“双基”的教学，并不意味着单纯的多讲、苦练，也不意味着为技巧化的训练而在一些细枝末节的内容上过度下功夫．这需要对“双基”的理解与掌握进行正确评价，及对数学“双基”教学新的认识和改进，从而促进数学“双基”教学科学有效地进行． 相似文献

"数学双基"问题的相关研究与思考 总被引：4，自引：1，他引：4
从我国中学数学教学大纲的沿革可看出我国数学教育中“ 双基” 的历史演进.对“ 双基” 界定的争议主要是由于一些人把技能与能力相混淆.为调和矛盾而产生的“ 广义的‘ 双基’ ” 的说法,不能解决这一问题.中国数学教学不等于“ 双基” 教学.学好双基、培养三大数学能力、培养分析问题和解决问题的能力、培养创新意识是我国数学教育发展的 4 个层次. 相似文献

数学教学中的“双基”，指一般约定基本知识和基本技能．但是，中国的数学双基教学，并非只抓双基，而是同样注重发展．不过，我们是强调在数学双基的基础上进行发展和创新． 相似文献

近读文卫星老师的课例“抽象函数（高三复习课）”，给人的感觉是它重“双基”，又不是传统的“双基”教学；它以解题为主，又不是传统的解题教学．可以说，它超越了“双基”，也超越了解题，是数学“双基”教学和解题教学的新探索．特别是由这一课例我们可以看到，在数学教育中．解题教学具有四个层次． 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
