摘要
从数学基本活动过程出发,数学基本活动经验可从维度划分和竖直层次水平两方面进行刻画。维度划分体现数学基本活动的过程,包括观察联想、归纳猜想、表达、验证或证明;竖直层次水平反映学生在数学基本活动各个方面达到的层次。测试结果表明:学生数学基本活动经验的总体状况一般;四个维度表现不均衡;通过聚类分析,得到学生数学基本活动经验的三级层次水平。
on the process of fundamental mathematic activity, this essay studies the experience ot fundamental mathematic activity from longitudinal aspect and horizontal aspect. Horizontal aspect shows the process of mathematic activities, which include observation, induction, expression and proving. Longitudinal aspect reflects students＇ level in each area. The researching result shows that students＇ experience of fundamental mathematic activity is rather mediocre and unbalanced. By using cluster analysis, this study presents three levels of students＇ experience of fundamental mathematic activity.
