重视试卷讲评,力争讲评到位是考试环节的重要组成部分,尤莫是高三阶段的试卷讲评,具有非常重要的特殊意义.每次考试后由试卷反映出的学生复习中的得与失、成绩与不足,要通过总结讲评来解决.只有通过及时的讲评、全面的总结、科学的分析才能及时发现学生知识的缺陷,夯实、巩固其基础知识,以期提高审题和解题能力与技巧,从而提高复习的质量. 相似文献

讲评课是高三复习的基本课型.讲评主要是总结取得成绩的经验,记取犯错丢分的教训,再现考试命题的情境.讲评能否做到深入、透彻、精当、到位,直接关系到备考复习的效率.从这个意义上讲,讲评的技术也是教师高考备考能力的直接体现.笔者在实践中总结了讲评"五要",简述如下,供大家参考. 相似文献

"构筑单元知识结构网络"复习法 总被引：1，自引：0，他引：1
目前大多数初、高中学生进行物理单元复习时习惯于一个一个概念孤立记忆,一道一道题去解答,割袭单元各概念、定理和定律相互之间的内在联系,不利于理解和掌握基本知识和基本技能,往往事倍功半,我在教学实践中总结出“构筑单元知识结构网络”复习法。该复习法的依据是 相似文献

每个学年度在完成新课程的教学后,初中物理的教学就进入了最后的中考总复习阶段。物理总复习是学生对整个初中物理知识进行系统全面的巩固及再认识、深化过程。如何在有限的时间里获得最大的复习效果,采用有效的复习方法是关键。本人一直担任初三毕业班的物理教学,通过多年的实践与总结,探索出一套容易操作实施的“三轮复习法”,效果较好。下面谈谈有关“三轮复习法”的具体做法。 相似文献

在政治复习课中要经常让学生总结某部分的知识要点,学生往往是按照教材目录将各个章节的内容进行直线性罗列即算完成复习了,不仅效率低,而且容易遗忘.通过实践探究思维导图在复习过程中的应用,发现用思维导图进行知识归纳和总结,能使复习效率都得到较大的提高.作为一个近几年来新兴的研究视角,文章从思维导图和复习效率的关系进行分析,以期为基于思维导图的教育教学应用提供借鉴,为课堂效益年的活动提供支点. 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 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 problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 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

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献
