First, the problems in the teaching of mathematical concepts in primary schools

1. The introduction is improper and lacks scientificity.

Due to the lack of teachers' discipline accomplishment and the influence of daily concepts, some teachers introduce concepts inappropriately and lack scientificity, which leads to inaccurate understanding of concepts.

The following is a teacher's process of introducing the concept of reciprocal: today we are going to play a game called saying backwards. For example, if I say "1, 2", you say "2, 1", I say "1, 2,3" and you say "3,2,65438+". This phenomenon also exists in mathematics, such as "three-eighths is eight-thirds." "

The introduction method of this concept is unscientific, which will cause students to understand the concept unclear.

2. Attach importance to the conclusion and despise the process.

At present, some teachers teach concepts as reading concepts, instruct students to read concepts, make students recite definitions, ignore the understanding of the formation process of concepts, lack the explanation and analysis of concepts, and lack the understanding of the essential attributes and extension of concepts. After learning the concept in this teaching mode, students can not apply the concept content to specific topics well, and they will forget the concept over time.

Second, measures to solve the problem of mathematical concepts

Mathematics comes from life, and the construction of students' mathematical concepts is based on their existing knowledge and experience. Starting from the understanding of existing concepts in life, practical introduction can make students accept them better.

For example, when learning the concept of parallelogram instability, teachers can cite some objects made of this nature in life, such as school gates and telescopic walls hanging at home, and introduce the concept from specific examples in life, which can make students remember deeply and understand more easily.

The study of concepts is not limited to words, but to understand the real meaning behind words. Only with a deep understanding can we apply them better. The deeper and more accurate we are, the easier it is to apply what we have. Teachers should pay attention to the explanation of the meaning of the concept itself in concept teaching, so that students can deeply understand the essence of the concept.
