几何画板在农村初中二次函数教学中的应用研究
发布时间：2018-12-15 12:01
【摘要】：数学是具有较强逻辑性的基础学科,知识抽象,学生需要较高的学习能力;教师需要有扎实的专业知识背景、较强的逻辑思维和合理的推导能力;学校需要必要的辅助教学设备和辅助教学工具。在新课程改革背景下,产生了许多辅助数学教学软件,几何画板就是其中一种,它简单易学,功能强大,在国内中学数学教学中被广泛普及。二次函数是历年中考的重点和难点,它具有抽象性、变化性和综合性,需要学生具有一定的抽象思维能力和分析能力。而对于教师教育理念相对落后、教学条件差、硬件设施起步晚而且设备落后、班级学生基数大、学生学习能力普遍偏低的农村初中而言,学生要学会用二次函数相关知识解决实际问题,难度颇大。由于几何画板简单易学,对数学教师的技能要求不高,不需要过硬的硬件设施,符合农村教学条件。本文对几何画板辅助农村初中二次函数教学进行实验,对实验效果和问卷调查进行统计分析、对教学效果进行总结,得到结论:使用几何画版能够普遍提高学生的学习兴趣、能够提高学生学习二次函数的效果,尤其对中等成绩和低分段成绩的学生的辅助效果尤为明显,而农村初中学生的数学学习水平在中等成绩和低分段成绩的居多,所以几何画板在农村初中数学教学中的应用对提高农村初中学生的学习兴趣和总体数学成绩能够起到较为关键的作用。
[Abstract]:Mathematics is a basic subject with strong logic, knowledge is abstract, students need higher learning ability, teachers need solid professional knowledge background, strong logical thinking and reasonable deduction ability. The school needs the necessary auxiliary teaching equipment and the auxiliary teaching tool. Under the background of the new curriculum reform, there are many auxiliary mathematics teaching software, one of which is geometric Sketchpad, which is simple and easy to learn and has powerful function, which has been widely used in mathematics teaching in middle schools in China. Quadric function is the key and difficult point of the middle school examination over the years. It is abstract, changeable and comprehensive, which requires students to have a certain ability of abstract thinking and analysis. But for the rural junior middle school, the teacher education concept is relatively backward, the teaching condition is poor, the hardware facilities start late and the equipment is backward, the class student base is large, the student learning ability is generally low, It is very difficult for students to learn to solve practical problems with knowledge of quadratic function. Because the geometry drawing board is simple and easy to learn, the skill requirement of mathematics teachers is not high, and the excellent hardware facilities are not needed, which accords with the condition of rural teaching. This article carries on the experiment to the geometry drawing board to assist the rural junior middle school quadratic function teaching, carries on the statistical analysis to the experiment effect and the questionnaire survey, carries on the summary to the teaching effect, obtains the conclusion: the use of the geometry drawing version can generally enhance the student's study interest, It can improve the effect of learning quadratic function, especially for the students with middle grade and low segmentation, but the rural junior middle school students' mathematics learning level is mostly in the middle grade and low segmentation. So the application of geometric drawing board in mathematics teaching in rural junior high school can play a more important role in improving the students' interest in learning and overall mathematics achievement.
