交际思维是交际主体在交际过程中 ,为解决交际问题而进行的一种高级神经活动。从认识角度看 ,交际思维就是一种对交际信息进行加工处理的活动。外语教学的实质是交际。这表现在两个方面 :第一 ,外语课堂教学是一个交际思维过程 ;第二 ,外语课堂教学过程同时也是一个培养学生交际思维能力的过程。外语教学的最终目的是培养学生的交际能力 ,交际能力的获得离不开交际思维。根据外语课堂教学交际活动的特点 ,应该采取“引入—启动—输入—加工—输出”这五个步骤来培养和提高学生的交际思维能力 Communicative thinking is a high-level neural activity conducted by communicators in the communication process to solve communicative problems.
