课堂教学中合理的、到位的、有趣的问题设计不但能激发学生的思维,促进师生互动,而且能提高课堂教学效率,从而达到最佳的教学效果。问题梯度是指教师根据自身教学经验和学生的学习需求,在对教学要求进行准确把握的基础上,设置一些比较系统的问题,使问题具有合理的高度和层次。在数学课堂教学中进行有效的问题梯度设置,有利于调动学生学习的积极性和主动性,从而提高他们探究问题和分析解决问题的能力。一、遵循认知规律,感知形成过程
The reasonable, the place, the interesting question design in the classroom teaching can not only stimulate students’ thinking, promote the interaction between teachers and students, but also improve the efficiency of classroom teaching so as to achieve the best teaching effect. The problem gradient refers to the teachers based on their own teaching experience and students’ learning needs, based on the accurate grasp of the teaching requirements, to set some more systematic questions, so that the problem has a reasonable height and level. The effective setting of gradient in mathematics classroom teaching is helpful to mobilize the enthusiasm and initiative of students to improve their ability of exploring and analyzing problems. First, follow the law of cognition, perception of the formation process
