【摘要】：为了全面贯彻党的教育方针,推进素质教育,全国各地都进行了课程改革。在新课程改革中,数学作为一门基础学科,各校课改中都较重视。数学最突出的特点是高度的抽象性,因此,如何让课本上的知识“形象”起来,如何激发学生学习数学的兴趣,提高课堂效率,是当前数学老师考虑较多的问题。近几年来,多种数学教学软件走进课堂,在众多的数学教学软件中几何画板具有动态性,准确性,直观性,易用性,开放性的特点,对提高数学课堂效率有很大的帮助。利用几何画板使得学生“听数学”变成了“操作数学”,把抽象的数学转化成直观形象的数学。但是几何画板的普及使用后,一线教师对该软件的系统学习压力很大,课堂的重难点也不一定因为使用几何画板而变得容易理解,教师对几何画板认识不到位等,如何处理是本研究要解决的问题。本论文分为七部分,第一部分主要介绍本研究的背景及意义,提出研究的目的,研究成果给一线老师授课一些帮助,提高老师的备课效率,本论文的研究方法是文献法,访谈调查法和行动研究法。第二部分是现状研究及问题分析,通过相关文献分析研究,已有研究这些文章不能系统帮助老师提高几何画板的操作技能。第三部分主要调查本校初中数学教师使用几何画板教学存在的问题,调查发现,教师对几何画板的认识存在一些误区,实际操作水平还不能满足教学需求,还存在教学效果不佳的问题。第四部分主要介绍利用几何画板提高课堂效率的一些建议。第五部分针对数学教学中的三大模块:代数、几何、代数与几何综合,设计三个对应典型案例,在典型案例中呈现了如何使用几何画板的思考。第六部分描述了三个典型案例实施后,从学生的角度反映出几何画板适当应用后的教学效果。第七部分,是本论文的小结,总结本研究的优势和不足。采用本文建议的方法,能够减轻教师的负担,并且提升学生的学习兴趣,在一定程度上提高数学课堂效率。
[Abstract]:In order to fully implement the Party's educational policy and promote quality education, curriculum reform has been carried out all over the country. In the new curriculum reform, mathematics, as a basic subject, is paid more attention to in the curriculum reform of each school. The most prominent feature of mathematics is a high degree of abstractness. Therefore, how to make the knowledge "image" in the textbook, how to stimulate students' interest in learning mathematics and improve classroom efficiency is a more serious problem for mathematics teachers at present. In recent years, a variety of mathematics teaching software has entered the classroom. Among many mathematics teaching software, geometric drawing board has the characteristics of dynamic, accurate, intuitive, easy to use and open, which is of great help to improve the efficiency of mathematics classroom. Using geometric drawing board, students' listening mathematics becomes operational mathematics, and abstract mathematics is transformed into intuitionistic mathematics. However, after the popularization and use of geometric drawing board, the front-line teachers have a lot of pressure on the systematic study of the software, and the heavy and difficult points in the classroom are not necessarily easy to understand because of the use of geometric drawing board, and teachers do not have a good understanding of geometric drawing board, and so on. How to deal with it is the problem to be solved in this study. This paper is divided into seven parts. The first part mainly introduces the background and significance of this study, puts forward the purpose of the study, and the research results give some help to the front-line teachers to improve the efficiency of lesson preparation. The research method of this paper is the literature method. Interview survey method and action research method. The second part is the present situation research and the problem analysis, through the related literature analysis research, has studied these articles can not systematically help the teacher to improve the geometry drawing board operation skill. The third part mainly investigates the problems existing in the use of geometric drawing board by junior middle school mathematics teachers in our school. It is found that there are some misunderstandings in teachers' understanding of geometric drawing board, and the actual operation level can not meet the teaching needs. There is also the problem of poor teaching effect. The fourth part mainly introduces some suggestions to improve classroom efficiency by using geometric drawing board. In the fifth part, three corresponding typical cases are designed for the three modules of mathematics teaching: algebra, geometry, algebra and geometry synthesis, and the thinking on how to use geometric drawing board is presented in the typical case. The sixth part describes the teaching effect of the proper application of geometric drawing board from the point of view of students after the implementation of three typical cases. The seventh part is the summary of this paper, which summarizes the advantages and disadvantages of this study. The method suggested in this paper can lighten the burden of teachers, enhance students' interest in learning, and improve the efficiency of mathematics classroom to a certain extent.
