设计活动 (ProjectApproach)是近年来备受教育界关注的一种学习模式 .设计数学活动能让学生更自然 ,更直接地获得“数学过程”的体验 ;更深入、更广泛地去探求一些数学问题 .并且在学习的过程中 ,学生的兴趣差异及能力差异都将得到个别的照顾 ,从而激发出更大的学习潜能 .笔者 Project Approach is a learning model that has attracted much attention in education in recent years. Designing mathematics activities allows students to more naturally and directly acquire the experience of the “mathematical process”; to explore more mathematical problems in more depth and more extensively. And in the process of learning, students’ interest differences and differences in abilities will be individually taken care of, thereby stimulating greater learning potential.
