数学新课程标准鼓励每个学生亲自实践、大胆探索,积极地参与到教学活动中来,努力实现自主发展.上好讲评课对巩固双基、规范解题、熟练技巧、开阔思路、提高学生解决问题的能力、培养学生的创新意识等有着特殊意义.为了提高数学教学质量,我市教育局数学推进组老师们对数学讲评课提出了一些要求.以此为背景,笔者在教学实践中进行了尝试和探索.一、精心准备1.统计分析一是统计每题得分率(对得分率较低的试题应认真分析错误原因).二是统计每题出现的典型错误(若是无解题过程的选择题,填空题,还要找学生了解错误的结果是怎么做出来的).若受时间限制,则可采取抽样统计,但样本一般不应低于
The new mathematics curriculum standards encourage each student to personally practice, bold exploration, and actively participate in teaching activities, and strive to achieve self-development. Good comment on the consolidation of the double base, standardized problem-solving, proficiency in skills, broaden ideas, improve student solutions Problem ability and cultivate students’ sense of innovation has a special meaning.In order to improve the quality of mathematics teaching, Mathematics Education Division of our city teachers put forward some requirements for mathematics commentary class.Under this background, the author conducted in teaching practice Try and explore.A carefully prepared 1.Statistical analysis First, the statistics of each question score (the lower the score of the question should be carefully analyzed the cause of the error) Second, the statistical error of each typical question (if there is no problem-solving process Multiple-choice questions, fill in the blank question, but also to find students to understand the results of the error is how to make out.) If the time limit, you can take the sample statistics, but the sample should generally not be less than
