Language has always been an indispensable "excellent example of human wisdom" in human society. Language has the potential to enhance the ability to remember and explain concepts. Mathematical language is a scientific language, which refers to the expression of mathematical concepts, formulas, formulas, arithmetic rules, rules, problem-solving ideas and derivation processes. Mathematical language has the characteristics of accuracy, abstraction, conciseness and symbolism. Its accuracy can cultivate students' honesty and integrity, its abstraction is conducive to cultivating students' ability to reveal the essence of things, and its conciseness and symbolism can help students better summarize the laws of things and help them think.
The overall goal of the new curriculum standard requires: learn to cooperate with people, and be able to communicate with people about the process and results of thinking, clearly explain their own views and make sense, and use mathematical language to discuss and ask questions logically in the process of communicating with people. The standard has different requirements for mathematical languages in different fields. In class, we find that some students want to speak but can't, some students dare not speak, and some don't speak at all. The use and expression of students' mathematical language is still far from the requirements of the Standard.
Based on the above situation, the author analyzes the reasons, and holds that: ① Mathematics classroom teaching is limited by the traditional educational tendency of "focusing only on results, ignoring process" and "only knowing how to do without dictation", and is infringed by exam-oriented education, which makes students lack opportunities for language practice, thus restricting the display of students' thinking. (2) Teachers don't know enough about the function of mathematical language and neglect the cultivation of students' mathematical language, which leads to the inaccuracy, nonstandard and imprecision of students' mathematical language and hinders the development of students' thinking. (3) Limited by the number of classes, there are too many students, some introverted students want to talk but can't speak clearly, and some good students often have no patience to listen. Over time, these students can't express mathematical language accurately and standard. ④ Students' own reasons are mainly influenced by non-intelligence factors.
To sum up, in today's primary school mathematics classroom teaching, it is imperative to strengthen the cultivation of students' mathematical language ability.
First, teachers' accurate and standardized mathematical language has a subtle influence on students.
Teachers' words and deeds have a subtle influence on students, so we should cultivate students' mathematical language expression ability, standardize teachers' language and set an example for students. Mathematics teachers should accurately describe concepts, laws and terms, and don't let students have doubts and misunderstandings. To this end, teachers should do the following two things: First, they should have a thorough understanding of the essence of concepts and the meaning of terms. For example, if we confuse "divide" with "divide", "number" with "number", and "number" with "number", we violate the law of identity. Some teachers instruct students to draw pictures, saying that "these two straight lines are not parallel enough" and "this right angle is not drawn at 90", which violates the law of contradiction. However, languages such as "the figure composed of three sides is a triangle" and "leap year is a multiple of 4 in the Gregorian calendar year" lack accuracy. Second, it must be explained in scientific terms. For example, we can't say "vertical line" as "vertical downward line" or "simplest fraction" as "simplest fraction". In addition to accuracy, rigidity should also have normative requirements. For example, speak clearly, read sentences clearly, and insist on using Mandarin. Conciseness means that the teaching language should be clean, important words should not be lengthy, focus on the key points, be simple and targeted; According to the age characteristics of primary school students, say what they are easy to accept and understand; Be accurate, don't beat around the bush, and deliver more information in a shorter time.
Second, let students train their mathematical language expression ability in oral expression.
In order to train all students' mathematical language, teachers can flexibly use the training mode of "deskmate communication, group discussion, classroom evaluation and student summary", and implement the teaching idea of "language training as the main line and thinking training as the main body" in classroom teaching, so that students at different levels can have something to say, stimulate students' enthusiasm for speaking and improve their speaking ability in positive evaluation.
