函数是对事物动态关系的数学呈现.初中生的逻辑思维能力培养主要在函数学习部分.本文主要分析苏教版“二次函数”教学实践.在函数教学中,既要为不同知识建立逻辑联系,又要从学生认知经验出发,灵活教学.要把生活中的实际问题作为典例,打消学生的神秘感和敬畏感.当前,随着对教育与学生终身发展之间关系的深入阐释,对课堂作用重新定位的呼声越来越高,课堂的关注点已经发生转移.既强调在价值层面唤醒学生自主意识,又强调在素质层
Function is a mathematical representation of the dynamic relationship of things.The cultivation of logic thinking ability of junior high school students is mainly in the part of function learning.This paper mainly analyzes the teaching practice of Sujiao version “secondary function ”.In the function teaching, it is necessary to set up different knowledge Logical connection, but also from the cognitive experience of students, flexible teaching should take the practical problems in life as a model to dispel the mystery and a sense of awe.At present, as the relationship between education and the lifelong development of students in-depth Interpretation, the role of the classroom to re-positioning the voice of higher and higher, the classroom has shifted the focus of attention not only emphasize the level of self-awareness of students wake up, but also stressed that the quality of the layer
