【摘要】：近年来,义务教育阶段的教学强调帮助学生“建立数感和符号感”,此处的“符号意识”就是字母表示数。学生对字母表示数的理解水平的高低决定了学生从算术学习过渡到代数学习的快慢,也为将来的代数学习奠定了基础,所以要让学生建立起代数思维就是要让学生理解掌握字母表示数所包含的内容。本文着重于研究5—7年级的学生在字母表示数的学习过程中出现的问题以及外界因素对其的影响。在整个调查过程中,笔者对5—7年级的410名学生在字母表示数方面进行了调查问卷,对6名教师和12名学生进行了访谈,根据SOLO理解水平划分,最终得出结论：现如今大多学生的抽象代数思维存在很大问题,在字母表示数方面,5年级学生多处于单一结构水平,6年级学生多处于多元结构水平,而七年级只有少部分能够达到关联结构水平。造成这种局面的因素有很多,笔者通过调查问卷和访谈总结出,学生的数学阅读能力较弱,并且在两个学段的衔接方面存在问题。最后笔者就以上两个方面提出建议。
[Abstract]:In recent years, the teaching of compulsory education emphasizes helping students to "establish sense of number and sense of symbol". The level of students' understanding of alphabetical representation numbers determines the speed of students' transition from arithmetic learning to algebraic learning, and lays the foundation for future algebraic learning. Therefore, to set up algebraic thinking is to make students understand the contents of alphabetical representation. This paper focuses on the problems in the learning process of alphabet representation and the influence of external factors on the students in grades 5-7. In the whole investigation process, the author investigated 410 students in grades 5-7 in terms of alphabetical representation, interviewed 6 teachers and 12 students, and divided them according to the level of SOLO understanding. Finally, it is concluded that there are great problems in abstract algebraic thinking of most students nowadays, and most of the fifth graders are at a single structural level in the alphabetical representation of numbers, and most of the sixth graders are at the multi-structural level. Only a small part of the seventh grade can reach the level of correlation structure. There are many factors that cause this kind of situation. The author concludes by questionnaire and interview that the students' reading ability is weak and there are some problems in the connection of the two learning paragraphs. Finally, the author puts forward some suggestions on the above two aspects.
