问答式教学方法设计——以密码学课程为例

Design of Question and Answer Teaching Method——Taking Cryptography Course as an Instance Example

现代高等教育专注于学生视野的开拓和知识面的延伸,对学生快速掌握学科知识有较大帮助,却很大程度上忽视了学生自主思维创新和自我能力塑造环节,导致学生在思维格局和创新能力上有较大欠缺。针对该问题,结合密码学教学内容和规律,尝试从传统问答式教学方法出发,结合理工科专业知识学习的思维模式,探索以问答互动和思维推导为核心步骤的教学方法设计,并以密码学理论教学为例,分别从理论支撑、备课步骤、实施方法和效能评估4个方面论述了问答式教学方法实施的可行性。

The modern high education focuses on the expansion of students’ vision and the extension of their knowledge,which is helpful for students to quickly grasp the subject knowledge. However,it largely ignores the link of innovative thought and self-ability shaping,which leads to the lack of students’ thinking pattern and ability innovation. In view of this problem,combining with the teaching content and rules of cryptography,this paper tries to start from the traditional question and answer teaching method and combine with the thinking mode of science and engineering professional knowledge learning to explore the design of teaching method with question and answer interaction and thinking inference as the core steps,and takes the teaching of cryptography theory as an example,discuss the feasibility of question and answer teaching method from four aspects:theoretical support,lesson preparation steps,implementation methods and effectiveness evaluation.
