创设问题情境是数学教师组织课堂教学的重要手段,问题情境创设得好,可极大提高学生的学习积极性与主动性,进而更好地实现教学目标。优化初中数学课堂的问题情境可考虑从以下三方面入手:一、优化问题的展现方式;二、优化问题的难度、梯度和角度;三、优化对学生回答的及时评价。 The establishment of the problem situation is an important means for teachers to organize classroom teaching in mathematics. The problem situation is well established, which can greatly improve the enthusiasm and initiative of the students in learning so as to achieve the teaching goal better. Optimization of junior high school mathematics classroom problem situations can be considered from the following three aspects: First, the optimization of the presentation of the problem; Second, to optimize the difficulty of the gradient and angle; Third, optimize the timely evaluation of student responses.
