数学概念的教学是一切数学知识从初步认识、深刻理解到熟练应用的基础,它是学生学好数学的前提和保障.恰当合理的教学方法可使学生头脑中形成正确的数学概念,从而使学生在后来的学习中形成完整的、清晰的、系统的数学知识体系.否则会使学生在学习过程中形成模糊的甚至是错误的 The teaching of mathematics concept is the foundation of all mathematics knowledge from preliminary understanding, profound understanding to skilled application. It is the prerequisite and guarantee for students to learn mathematics. Appropriate and reasonable teaching methods can make students form the correct mathematical concepts in the mind, so that students can A complete, clear and systematic knowledge system of mathematics will be formed in later learning. Otherwise, students will become vague or even wrong in the learning process.
