【摘要】：在21世纪,以知识经济为主导的信息技术正在快速发展,国内外越来越重视教育信息化。尤其对以培养逻辑思维著称的数学学科而言,其教学不仅要求教师具有深厚的数学专业知识,还需要掌握一定现代信息技术,传统的黑板式教学己经难以满足信息时代发展的需要。新课程改革提倡将现代教育技术融入数学课堂,但如何在数学课堂上高效运用信息化教学软件,一直是数学教师亟待解决的问题。在常用的教学软件中,几何画板具有动态演示、作图精准、度量、计算、数学实验等功能,能更好的优化初中数学课堂教学。本研究采用文献研究法、问卷调查法和综合分析法,分析并研究初中数学教学现状。首先,概述了课题研究的背景及国内外几何画板辅助数学教学现状。其次,阐述了课题研究的基础,包括几何画板的功能与价值、相关文献综述和研究的理论依据。此外,基于初中数学三大知识板块,对几何画板在函数、几何以及概率统计中的应用案例进行了分析探讨,并以二次函数和勾股定理为教学案例,对其应用几何画板进行了设计。本研究旨在为初中数学教学改革注入新的活力,为几何画板应用于初中数学课堂教学提供理论和实践的参考,以便真正让几何画板成为辅助初中数学教学的有力工具。
[Abstract]:In the 21st century, the information technology, which is dominated by knowledge economy, is developing rapidly, and more attention has been paid to the education informatization at home and abroad. Especially for the mathematics subject, which is famous for cultivating logical thinking, its teaching not only requires teachers to have profound knowledge of mathematics, but also needs to master certain modern information technology. Traditional blackboard teaching has been difficult to meet the needs of the development of the information age. The new curriculum reform advocates the integration of modern educational technology into mathematics classroom, but how to efficiently use information teaching software in mathematics classroom has always been a problem to be solved by mathematics teachers. In the common teaching software, the geometric drawing board has the functions of dynamic demonstration, accurate drawing, measurement, calculation, mathematical experiment and so on, which can better optimize the mathematics classroom teaching in junior high school. The present situation of mathematics teaching in junior high school is analyzed and studied by literature research, questionnaire survey and comprehensive analysis. Firstly, the background of the research and the present situation of Geometry Sketchpad aided mathematics teaching at home and abroad are summarized. Secondly, the basis of the research, including the function and value of the geometric Sketchpad, the related literature review and the theoretical basis of the research are expounded. In addition, based on the three knowledge blocks of mathematics in junior high school, the application cases of geometric drawing board in function, geometry and probability statistics are analyzed and discussed, and the quadratic function and Pythagorean theorem are taken as teaching cases. The geometric drawing board is designed. The purpose of this study is to inject new vitality into the reform of mathematics teaching in junior high school, and to provide theoretical and practical reference for the application of geometric drawing board in mathematics classroom teaching in junior high school, so that geometric drawing board can become a powerful tool to assist mathematics teaching in junior high school.
