一直以来,概念教学是高中数学教学的重点内容,因为高中生只有在学好数学概念的基础上才能更好地对其他数学知识进行学习。在“呈现概念——讲解概念——运用概念”的单一的、静态的教学模式,高中生接受与理解数学概念是被动的。在“学为中心”的高中数学课堂教学中,教师要善于从以下五方面进行数学概念教学的优化,以此促进高中生对数学概念的感知与理解。一、联系生活实际,引入数学概念任何一个数学概念或是生活中一些数
Conceptual teaching has long been a focus of high school mathematics teaching, because high school students can learn other mathematics knowledge only if they learn the concepts of mathematics well. In the single, static teaching model of “presentation concept—presentation concept—using concept”, high school students are passive in accepting and understanding mathematical concepts. In the “study-centered” high school mathematics classroom teaching, teachers should be good at optimizing the mathematics concept teaching from the following five aspects, so as to promote the perception and understanding of mathematics concepts of high school students. First, link life to reality, introduce mathematical concepts to any mathematical concept or number of life
