2011年,中华人民共和国教育部颁布《义务教育数学课程标准》.在新课标的指引下,各地的中考进行了相应的改革,试题内容涉及“数与代数”、“图形与几何”、“统计与概率”、“综合与实践”四个学习领域.概率试题由于难度不大,很多教师在教学的过程中往往重视不够,中考前常让学生通过多练习相应题目而达到熟练掌握.但此办法不利于学生后继的学习,对学生数学能力的培养是不利的.所以本文就概率的深层次掌握:模型归一,结合笔者教学过程中的所思所得与读者交流.
In 2011, the Ministry of Education of the People’s Republic of China promulgated the “Curriculum Standard for Compulsory Education Mathematics.” Under the guidance of the new curriculum standards, all the secondary entrance examinations underwent a corresponding reform. The contents of the examination questions covered “Number and Algebra”, “Pattern and Geometry ”,“ Statistics and Probability ”, “ Comprehensive and Practice ”Due to the difficulty is not difficult, many teachers often pay insufficient attention to the teaching process, before the senior high school entrance examination often let students through the practice of the corresponding But this method is not conducive to students ’subsequent learning, which is unfavorable to students’ mathematical ability training.Therefore, in this paper, the deep mastery of probability: model normalization, combined with the author’s thinking process in the process of learning and readers communicate with.
