【摘要】：现代信息技术改变了数学教学和数学学习的方式。如何使用现代信息技术提高高三数学复习的效率,如何利用现代信息技术提高学生数学学习的兴趣,是一个急需解决的问题。几何画板由于具有“动、准、直、易”等特点成为开展高三文科班数学实验的最佳的软件平台。本研究的主要目的是探讨应用几何画板开展高三文科班数学实验的教学策略及应用这些策略开展数学实验的有效性。基于理论的指导和现实的诉求,本研究以非示范性普通高中高三年级两个文科班的学生为研究对象,通过经验总结和理论思辨、实验研究与课例研究相结合的方法,研究了应用几何画板开展高三文科班数学实验的教学策略。具体而言,本研究主要做了如下几个工作：首先在理论方面,查阅相关资料,在大量阅读的基础上总结提炼几何画板的特点,高三文科数学教学的基本特点,几何画板在高三文科数学教学的基本作用并提出了应用几何画板开展高三数学实验的教学策略：优化数学概念教学的策略、优化数学命题教学的策略和优化数学解题教学的策略。其次,在实践研究方面,以教学实践为主,调查分析、课例研究为辅,探讨所提出的策略对改善高三文科班学生数学成绩和学生对数学的兴趣态度是否有效。研究表明：(1)应用几何画板开展高三文科班数学实验,能显著提高高三文科班的数学成绩,且在学优生、学中生和学困生三个层面都有显著地的提高。(2)应用几何画板开展高三文科班数学实验,能提高学生的数学学习兴趣,促进对数学的理解,提高自主学习的水平。
[Abstract]:Modern information technology has changed the way of mathematics teaching and learning. How to use modern information technology to improve the efficiency of senior three mathematics review and how to use modern information technology to improve students' interest in mathematics learning is an urgent problem to be solved. Geometric drawing board is the best software platform to carry out mathematics experiment in senior three liberal arts class because of its characteristics of "moving, accurate, straight and easy". The main purpose of this study is to explore the teaching strategies and the effectiveness of using geometric drawing board to carry out mathematical experiments in senior three liberal arts classes. Based on the guidance of theory and the demand of reality, this study takes the students of two liberal arts classes in the third grade of non-exemplary high school as the research object, and combines the experimental research with the case study through the experience summary and theoretical speculation. This paper studies the teaching strategy of using geometric drawing board to carry out mathematics experiment in the third liberal arts class of senior high school. Specifically, this study mainly does the following work: first, in theory, referring to relevant materials, on the basis of a large number of reading summarized the characteristics of geometric drawing board, the basic characteristics of mathematics teaching in senior three liberal arts, The basic function of geometric Sketchpad in Mathematics Teaching of Senior three Liberal Arts and the teaching strategy of applying Geometry Sketchpad to carry out mathematics experiment in Senior three: the strategy of optimizing the teaching of mathematical concept, Optimize the strategy of mathematics proposition teaching and optimize the strategy of mathematics problem solving teaching. Secondly, in the aspect of practical research, this paper focuses on teaching practice, investigation and analysis, and case study, and discusses whether the proposed strategies are effective in improving students' mathematics scores and students' interest in mathematics in senior three liberal arts classes. The results are as follows: (1) using geometric drawing board to carry out mathematics experiment of the third liberal arts class in senior high school can significantly improve the mathematics achievement of the third liberal arts class, and it can also be used to study the excellent students in senior high school. The three levels of secondary students and students with learning difficulties have significant improvement. (2) the application of geometric drawing board to carry out mathematics experiments in senior three liberal arts classes can improve students' interest in mathematics learning, promote their understanding of mathematics and improve the level of autonomous learning.
