《全日制义务教育数学课程标准(实验稿)》把统计与概率作为课程教学内容的四个学习领域之一,并把培养统计观念作为数学课程的重要目标。教师若忠实执行专家编制的统计课程教材必然扼杀了教师的主体性,那么摒弃了忠实取向,教师作为课程的开发者,创新课程又能否保证教师创设的具体的统计教学活动是有效的呢?笔者就第一学段“数据统计活动初步”的具体目标结合课堂教学实例,探讨如何提高低年级统计教学的有效性。 Full-time compulsory education mathematics curriculum standard (experimental draft) “the statistics and probability as one of the four learning areas of teaching content, and to develop statistical concepts as an important goal of mathematics courses. If teachers faithfully implement the statistical curriculum compiled by experts must stifle the subjectivity of teachers, then discard the loyalty orientation. Teachers as curriculum developers, innovative courses can guarantee that teachers create specific statistical teaching activities is effective? The author of the first session of ”preliminary" statistical activities combined with the classroom teaching examples, to explore how to improve the effectiveness of lower grade statistical teaching.
