对农村八年级学生理解二次根式的分析研究
发布时间：2019-02-25 13:41
【摘要】：二次根式是初中数学的重点内容之一,也是难点之一。学习二次根式时已经学习了平方根、算术平方根以及立方根等内容。从形态表象看二次根式的定义实质就是一个非负数的算术平方根,二次根式是“实数”的一部分,它是对“代数式”及“实数”等知识的补充和延伸,学习二次根式是为了更好的学习函数及代数式的相关内容。本文通过对四川崇州153名农村中学学生的问卷调查和部分访谈,考察了八年级学生对二次根式定义的理解,性质的理解和应用。本文共五章,第一章主要说明问题的产生,以及研究本文的意义;第二章是根据现有的研究,从四个方面进行概括,为本文后面的研究打下基础;第三章主要是通过对调查报告的分析得到学生对二次根式的掌握水平,并与学生交流得到相应结论;第四章主要是结合前面的研究得到一些结论和教学建议;第五章是结合实际情况说明研究存在的不足和以后的努力方向。
