中文摘要：

教学模式改革是教学改革的基础环节。新模式由3部分组成，包括：建设开放式网络教学平台，支持基于E—Learning的主动式、交互式教学；设置多样化教学环节，推动问题启发式、任务驱动式和合作式教学；采用全英语授课，促进浸入式、集中式教学。运用数学模型讨论了3种教学方法之间的约束关系。实践表明，在信息安全专业外语教学改革中，新型学习模式的应用能够有效增强学员的学习主动性，显著提升听、说、读、写、译5个方面能力。

英文摘要：

The reform of teaching mode is the basic link of the education reform. Many kinds of teaching methods are applied to construct the mode. The new mode consists of three parts. The first work is implementing an open online E-learning system that can improve initiative learning and interactive teaching. Then set up diversified teaching programs to pro- mote the cooperative, heuristic and task-based learning. Thirdly, in-class English immersion is adopted to enhance learning environment. The mathematical formula describes the con- straint relationship among these parts. The experimental group pays more attention to affec- tire factors, such as motivation, interest and anxiety. Reading, listening, speaking, transla- ting and writing skills are reinforced significantly.
