根据当前高中数学教学模式来看,数学课堂的组织形式主要有:问题情境→学生活动→意义构建→数学理论→回顾反思.问题情境作为整节课堂的开端,发挥着关键的作用.问题情境的创设是高中数学课堂成功的一半.运用合适的方式创设问题情境,有助于课堂内容的承上启下,建立丰富的知识结构网络,激发学生的学习兴趣,培养学生的创新意识和实践能力.那么,如何在高中数学教学中创设问题情境呢?一、以旧带新,创设问题情境
According to the current high school mathematics teaching model, the main forms of math classroom organization are: problem situation → student activity → meaning construction → mathematical theory → retrospective reflection problem context as the beginning of the entire section of the classroom, play a key role. Creating is half of the success of high school mathematics class.Using the appropriate way to create a problem situation is conducive to the up and down of the classroom content, to establish a rich network of knowledge structure, to stimulate students ’interest in learning, to develop students’ innovative awareness and practical ability. In high school mathematics teaching to create a problem situation? First, old with new, create a problem situation
