2、越来越成为当前数学教 育改革的一个热点。我国不仅首次把数学建模写入数学新课程标准,而且明确指出数 学建模是贯穿于整个高中数学课程的重要内容,这些内容不单独设置,而是渗透在每 个模块或专题中。可见,数学建模在中学受到前所未有的重视,中学数学建模教学也 将是数学教育工作者积聚力量重点研究的课题。因此,培养中学生的数学建模能力作 为中学数学建模教学的主旨,值得进行一番细致的推敲。 本文通过利用文献分析法、专家访谈法、历史研究法等研究方法,在新课程标准 下开展中学数学建模活动要求的基础上,对中学生数学建模能力的培养进行了探讨, 旨在拟出一套具有较强操作性、行之有效的培养中学生数学建模能力的方法,切实提
3、 高中学生应用数学思想和数学知识去解决实际问题的能力,努力推进中学数学建模活 动的全面开展,进而推动数学教育改革。 论文共分四个部分,第一部分介绍国内外中学数学建模教学现状,并着重分析目 时国内中学数学建模教学存在的一些问题 f然后阐述中学生数学建模能力培养的理论 基础,其中结合高中数学课程的新理念,提出两种适合中学生学习数学建模的学习方 式;第二部分分析中学数学建模能力的要素及其影响因素,并结合案例分析说明各要 素的作用;第三部分探讨中学数学建模能力的培养策略和培养方法,并配有案例加以 说明,以期给当前的数学建模教学提供教学思路:第四部分论述中学数学建模教学设 计的原则和内容选择原则,并分别
4、设计了适合初中生、高中生的教学案例,而且对案 例作了有针封性的分析。 数学建模能力是一个综合应用能力,对数学建模能力的培养要经历一个长期的过 程。通过本文的研究希望能够提高学生的问题解决能力,培养学生的数学应用意识, 提高他们的数学素养,并应用到 4前的数学建模教学中,为中学数学建模活动的开展 而服务,进血促进新课程的实施。 关键词:数学建模,能力,培养 The research on training ability of mathematical modeling in high school according to the new course standard Abstract Ma
