【摘要】：函数是近现代数学的基石,是数学学科的纽带,也是中学数学中最核心的内容之一,二次函数不仅是初中阶段至关重要内容,而且也是高中学习的重要基础。众所周知,对于初中阶段二次函数的内容,无论是学生的学还是教师的教都存在诸多的困难,这是一个值得研究的课题。本文在查阅有关二次函数图象与性质的文献的基础上,通过问卷调查法、访谈法并结合自身教学经验,具体分析总结学生在二次函数学习中遇到的困难、学习困难的具体原因所在;教师对待图象与性质教材内容的看法,在教学中遇到的困难及应对措施。在此基础上结合自己的教学经验,根据教学的实际情况提出具有针对性的改进提高的方案措施。调查及访谈结果显示造成二次函数图象与性质教学效果不佳的难点主要表现在:一是本身具有一定的难度,二是二次函数的性质具有一定的抽象性,学生理解困难,三是学生思维水平的限制,思想方法,思维习惯的养成,本文主要从函数图象与性质的三个主要方面出发提出相应的教学策略,并以两节具有代表性的课时做出课堂教学设计。最后以实际教学情况为基础,通过不断的反思、总结、改进,以期望达到良好的教学效果。
[Abstract]:Function is the cornerstone of modern mathematics, the link of mathematical disciplines, and one of the core contents of middle school mathematics. Quadratic function is not only the most important content of junior middle school stage, but also the important basis of high school learning. On the basis of consulting the literature about the image and nature of quadratic function, this paper analyzes and summarizes the difficulties that students encounter in learning quadratic function, and the specific reasons why teachers treat images and properties of quadratic function. On the basis of this, combining with my own teaching experience, this paper puts forward some suggestions to improve the teaching quality according to the actual situation of teaching. The second is that the nature of the quadratic function is abstract. The third is that the students have difficulty in understanding. The third is the restriction of the students'thinking level, the cultivation of their thinking methods and habits. Make a classroom teaching design. Finally, based on the actual teaching situation, through continuous reflection, summary, improvement, in order to achieve good teaching results.
