The purpose of this paper is to solve the current translation teaching problems, and to provide a new kind of computer-aided translation teaching mode. Constructivism is the theoretical foundation of the thesis and computer-aided translation teaching mode. Constructivism holds that students are not passive recipients but subjects of the cognitive process and active constructors of knowledge. The final result of new mode is that the dominant role of teachers decreases and self-control learning capacity of students increases. The new mode also advocates collaborative learning, which can be reflected respectively in the changes of translation teaching materials, teaching environment and the way of teacher-student interaction.
