近几年,初中数学竞赛试题的难度降低,考察重点多放在数学思想的具体应用上.在代数方面,尤其是二次函数与二次三项式、二次方程、二次不等式的密切类系,使竞赛与新课标密切联系起来,竞赛是课本知识的延伸与综合的运用,真正体现了数学学习的有效性.现对2007年全国初中数学联合竞赛试题分析如下: In recent years, the difficulty of the junior high school mathematics contest questions has been reduced, and the focus of investigations has been mostly on the specific application of mathematical ideas. In terms of algebra, especially the close relationship between quadratic functions and quadratic terms, quadratic equations and quadratic inequalities. Department, the competition is closely linked with the new curriculum standard. The competition is an extension and comprehensive application of textbook knowledge and truly embodies the effectiveness of mathematics learning. Now the analysis of the national junior high school mathematics competition in 2007 is as follows:
