在数学课堂教学中,创设问题情境是教师经常采用的一种教学手段,是教师基本功的集中反映。好的问题情境能激发学生思维的火花,凝聚学生的注意力,唤起学生的好奇心、求知欲和创造力。问题情境已成为沟通现实生活与数学学习、具体问题与抽象概念之间的一座桥梁,它在数学的学习中发挥着重要的作用,得到了广大教师的重视与响应。然而创设问题情境 In mathematics classroom teaching, creating problem situations is often used as a teaching method by teachers and is a concentrated reflection of teachers’ basic skills. Good problem situations can stimulate students’ thinking sparks, gather students’ attention, arouse students’ curiosity, curiosity and creativity. The problem situation has become a bridge between real life communication and mathematical learning, and between specific problems and abstract concepts. It plays an important role in the study of mathematics and has won the attention and response of the majority of teachers. However, create a problem situation
