随着新课程的实施,“问题解决”和“数学建模”引起了广泛关注,应用问题的教学也受到重视,训练力度明显加强.由于种种原因,部分问题在设计和解答上存在不少值得推敲的地方.为应用而应用,这既与我们以往对应用不够重视、应用题积累不多有关系,也与我们对数学应用理解的不到位有关系.因 With the implementation of the new curriculum, “problem solving” and “mathematical modeling” have attracted widespread attention, teaching of applied problems has also received attention, and training has been significantly strengthened. Due to various reasons, some problems are involved in design and solution. There are many places worthy of scrutiny. Applying for applications is not only related to our lack of attention to applications, but also to the fact that our understanding of mathematics applications is not in place.
