美国数学家哈尔莫斯认为,定理、证明、概念、定义、理论、公式、方法中任何一个都不是数学的心脏,只有问题是数学的心脏.教学活动是课程价值实现的重要因素,而课堂教学总是围绕问题进行的.[1]事实证明,课堂有效提问对于高效课堂生成起着至关重要的作用.有效教学的很重要的一点,就是要围绕课堂教学目标构建有效系统的“问题场”.教师该如何以问题为核心,发展学生的问题意识呢?结合多年的教学实践,本文略谈自己的一些体会.
Harmuth, the American mathematician, argues that the theorem, the proof, the concept, the definition, the theory, the formula and the method are not the heart of mathematics, but the problem is the heart of mathematics.Teaching activity is an important factor in the realization of the curriculum value, Teaching is always around issues.1 It has turned out that effective questioning in the classroom plays a crucial role in efficient classroom generation.It is very important for effective teaching that the question of building an effective system around classroom instructional goals Field ". How teachers to the problem as the core, the development of students’ problem awareness? With years of teaching practice, this article briefly talk about some of their own experience.
