<正>联想,是从一个问题到另一个问题的心理活动,是由此及彼的思维方法,是接通解题思维的桥梁.在数学解题中往往可以通过联想,找出相关的原理、方法、结论或命题,再灵活使用这些知识,则能达到准确简捷的解题目的.下面举例说明. 相似文献

2007年高考数学陕西卷文、理科各有一道数列解答题,我们对这两道题的解题过程分析希望能够体现解题反思的两个要点:解题方法的评价与数学命题的认识(参见文[1]P.159).其中文科试题的分析重在解题方法的评价,深化方法的认识,追求解法的优化;理科试题的分析重在数学命题的认识,经历冗余条件 相似文献

在数学教学中,解题是一种最基本的活动形式,无论是数学概念的形成,数学命题的掌握,数学方法与技能的获得,还是学生能力的培养与发展,都是通过解题活动来完成的.同时解题也是评价学生认知水平的重要手段.波利亚说：＂中学教学的首要任务就是加强解题训练”、“掌握数学就是意味着善于解题”。 相似文献

作为数学教育任务的数学解题 总被引：8，自引：0，他引：8
作为数学教育任务的数学解题与数学家的解题既有联系又有区别.它触及数学教育的3个基本矛盾,需要回答两个基本问题:怎样解题?怎样学会解题?解题理论建设成为一个独立分支有3个标志.解题研究已初步积累有题、解题、解题过程、解题程序、解题力量、解题方法、解题策略、数学问题解决的基本框架等成果.学会解题需要经历4个阶段:简单模仿、变式练习、自发领悟和自觉分析. 相似文献

Postmodern theory is used to consider literacy instruction with and without an electronic whiteboard to investigate what it means to move beyond using technology to replicate older models of classroom structure that may be historically situated but that also limit or at least, do not support engagement in ways that may be possible through use of new technologies. Using postmodern theory in this regard is a way in which to consider again the thoughts and practices that tend to construct identities and ideologies in ways that work against true engagement in literacy tasks, lead to subjection and demonstration of acquiescence in place of engagement that leads to participation and critical engagement. Critical engagement as opposed to gaining and maintaining student attention to task are considered in this paper. Thinking about use of the electronic whiteboard from a postmodern perspective cautions us about careful use of this technology to avoid sending messages to students about them and their role in literacy development, the classroom, and in society. 相似文献

Intended as an introduction and overview, this article previews the other contributions to the topic and places them in a general introductory context. The basic question is why women, who are not currently confronted with legal or overt discrimination with regard to entering and even thriving in academic careers, are still underrepresented in the academic world in Europe, particularly in the upper echelons of academic governance and power. Several possible explanations are given, in particular the failure of women to be prepared from an early age to be competitive in ways which boys are taught to take for granted, and their failure, not so much to engage in networking, but to penetrate the networks which count, most or all of which are in fact male dominated. Among the strategies which women may use to gain both presence and power in the academic world, the use of women's studies programmes is ruled out as being ultimately counterproductive. Likewise doubt is cast on the long‐term effectiveness of affirmative action programmes. Only remedies specific to the individual conditions of each country will be really helpful in aiding women to be more numerous in higher education, particularly in positions of power. However, in all the countries in question, women must be socialized so as to be willing to adopt behaviours conducive to academic success, and they must bring to bear the full resources of the social protection and welfare systems, all of which in the different countries of the Europe Region favour not only the progress of women, but the rational use of human resources. 相似文献

One of the most important issues in the reorganisation of engineering education is to consider new pedagogical techniques to help students develop skills and an adaptive expertise. This expertise consists of being able to recognise the nature of a problem intuitively, and also recognising recurring patterns in different types of problems. In the particular case of analogue electronics, an additional difficulty seems to be that understanding involves both analytic skills and an intuitive grasp of circuit characteristics. This paper presents a proposal to help senior students to think intuitively in order to identify the common issue involved in a group of problems of analogue electronics and build an abstract concept based on, for example, a theory or a mathematical model in order to use it to solve future problems. The preliminary results suggest that this proposal could be useful to promote intuitive reasoning in analogue electronics courses. The experience would later be useful to graduates in analytically solving new types of problems or in designing new electronic circuits. 相似文献

This article describes current developments in regard to quality assurance and the recognition of higher education qualifications in Lithuania. With the aim of internationalizing its higher education system, Lithuania acceded to the UNESCO European Diploma Convention in 1994 and to the Council of Europe Convention on the Equivalence of Diplomas Leading to Admission to Universities in 1996. The Ministry of Education created the Lithuanian Centre for Quality Assessment in Higher Education in January 1995. It has been very active in a number of directions since then. In addition, Lithuania has subjected its science to international evaluation, is a partner in the Baltic Higher Education Coordination Committee, and is participating in two PHARE projects for the development of co‐operation in higher education. The main obstacle to greater co‐operation in regard both to the recognition of academic qualifications and to quality assurance is lack of financial resources. 相似文献

The purpose of this study was to test the effectiveness of a cognitive motivational model of course selection patterns to explain the continued participation of men and women in college science courses. A number of cognitive motivational constructs were analyzed in a path model and their effect on students' intention to continue in college chemistry was determined. Variables in the model included self-perceived ability in science, future expectations, level of past success, effort expended, subjective interpretations of both past success and task difficulty, and the intention to continue in college chemistry. The results showed no sex differences in course performance, the plan to continue in chemistry, perceived ability in science, or past achievement in science courses. The path analysis did confirm the usefulness of the cognitive motivational perspective to explain the intention of both men and women to continue in science. Central to that process appears to be a person's belief about their ability. Students who had confidence in their ability in chemistry expected to do well in the future and were more likely to take more chemistry. Ability ratings in turn were dependent on a number of past achievement experiences and the personal interpretation of those experiences. 相似文献

否定转移是指位置上与一个词或短语放在一起的否定词,有时在意义上或逻辑上可转移到去否定另一个词或短语。通过总结英语否定转移的四种表达方式,即从一般否定转移到特指否定;从特指否定转移到一般否定;从一种特指否定转移到另一种特指否定;从否定主句谓语动词转移到否定从句谓语动词,来探讨其在汉语中的翻译,以期进一步提高翻译的准确性。 相似文献
