几何画板在小学数学第二学段图形与几何教学中的应用研究
发布时间：2019-06-07 08:13
【摘要】：图形与几何教学在小学数学教学中有着一定的比重,但教学效果不是很理想。对于一些几何概念或是平面图形面积的推导,学生有时难以理解,而几何画板的出现则给小学数学图形与几何的教学带来了极大的便利。在信息技术与课程整合的背景下,如何利用其提高小学数学图形与几何的教学效果是教育者迫切关注的问题。几何画板具有一定的动态展示、计算等功能,符合教学的实际需要。首先,本研究总结了国内外几何画板与小学数学图形与几何教学的研究情况,并在此基础上提出借助其来辅助小学数学图形与几何的教学。其次,了解小学数学第二学段教师进行图形与几何教学的现状,然后在此基础上阐述了适时利用几何画板辅助图形与几何教学的必要性;接下来,总结其在小学数学图形与几何教学中的应用类型;接着最重要的是在教师行动研究的基础上,探讨如何合理地运用几何画板辅助小学数学第二学段图形与几何的教学,并通过问卷调查了解运用其进行教学的教学效果;最后提出几点关于运用几何画板辅助小学数学图形与几何教学的建议。
[Abstract]:Graphics and geometry teaching has a certain proportion in primary school mathematics teaching, but the teaching effect is not very ideal. For the derivation of some geometric concepts or plane graphic area, it is sometimes difficult for students to understand, and the appearance of geometric drawing board brings great convenience to the teaching of mathematical graphics and geometry in primary schools. Under the background of the integration of information technology and curriculum, how to use it to improve the teaching effect of mathematical graphics and geometry in primary schools is an urgent concern for educators. Geometric drawing board has certain dynamic display, calculation and other functions, in line with the actual needs of teaching. First of all, this study summarizes the research situation of geometry drawing board and primary school mathematics graphics and geometry teaching at home and abroad, and on this basis, puts forward that it can assist the teaching of primary school mathematics graphics and geometry with the help of it. Secondly, it understands the present situation of graphics and geometry teaching in the second stage of mathematics in primary school, and then expounds the necessity of using geometry drawing board to assist graphics and geometry teaching in good time. Next, it summarizes its application types in primary school mathematics graphics and geometry teaching. Then, on the basis of teachers' action research, the most important thing is to explore how to use geometric drawing board reasonably to assist the teaching of graphics and geometry in the second learning section of mathematics in primary school, and to understand the teaching effect of using it through questionnaire survey. Finally, some suggestions on using geometric drawing board to assist primary school mathematics graphics and geometry teaching are put forward.
