谈谈数学建模能力培养的阶段性与题目的层次性

Stages and Topic Levels for Training Mathematical Modeling Ability

中学数学建模活动的开展对中学生数学素养的提高起到了积极作用．但在中学开展数学建模活动一定要结合中学生的年龄特点、知识结构和智力水平，结合正常教学的教材内容，分层次逐步推进．因此，学生的数学建模能力应分阶段培养，建模题目也应划分不同层次，从而达到面向全体学生，提高创造能力的目的．

The dcvelopment of activities of mathematical modeling (MM) in middle schools had played an active rolc in heightening the students' mathematical accomplishments. However, it was necessary that activities of MM be combined with their age characteristics, knowledge structures and intelligence levels and with normal teaching materials by advancing step by step and at levcls. Thus, their MMability should be trained by stages, and topics of MM differentiated at leveIs so as to facc all of them toraise their creativity ability.
