数学学习是一种经验性的活动,学生需要通过实际操作演算,动手做或是头脑中的操作——思想实验,才能形成对数学的全面认识.因此,作为新课程的一个具体目标,学生的数学综合与实践活动始终是课程、教学及其评价所应当特别关注的对象.所以多年来,河北省数学中考中始终考查一道“探究与实践活动”的大题,位于23或24题的位置,分值为10分.由于此题考察学生的探究活动和实践活动,所以阅读量大、背景新,成为师 Mathematical learning is an empirical activity, in which students need to make a comprehensive understanding of mathematics through practical calculations, hands-on exercises or mental operations - ideological experiments.Therefore, as a specific goal of the new curriculum, students’ Mathematics synthesis and practice activities is always the subject of curriculum, teaching and evaluation should be of particular concern.So over the years, Hebei Province math test always examines a “exploration and practice activities,” the big problem is located in 23 or 24 Position, the score is 10. Because this issue examines the student’s inquiry activities and practice activities, so read a large amount of background, new, become a teacher
