所谓问题情境,是指在新奇未知事物的刺激下学生在形成认识过程中突然提出问题或者接受提问,产生解决问题的强烈愿望,并作为自己学习过程目的的那一种情境。从学生已有的生活经验出发,让学生经历将实际问题抽象成数学模型并进行解释与应用的过程。在课堂教学中老师应为学生营造合适的问题情境,让学生在他们所喜欢的情境中进行教学活动,有利于激发学生学习的积极性,培养学生的思维能力,使课堂收到良好的效益。
The so-called problem context refers to that under the stimulation of novelty and unknown things, students suddenly ask questions or receive questions in the process of forming cognition, resulting in a strong desire to solve the problem and as a situation of their own learning process. Starting from the student’s existing life experience, students are subjected to the process of abstracting the actual problem into a mathematical model and explaining and applying it. In classroom teaching, teachers should create appropriate problem situations for students to teach students in the situations they like. It is conducive to motivating students ’enthusiasm for learning and cultivating students’ thinking ability so that the classroom can receive good benefits.
