摘　　要：挑战性课程能够在发现问题、自主学习、交流表达和团队管理等诸多方面提高学生的主动性,是非常重要的教学方式。鉴于部分应用型课程涉及的知识点分散,若采取单个挑战任务的教学模式,课程将很难覆盖所有必要的知识点,因此提出多目标、多阶段的挑战式教学模式,以满足实际的课程教学要求。以数据安全与取证技术挑战课程的教学实践为例,阐述了在该模式下如何根据知识点确定挑战目标与设计挑战内容。在确定多个挑战目标后,为了在教学中协调多挑战任务的实施,各挑战任务将划分为若干阶段并以叠瓦式方式进行部署。教学过程中需要合理设计各步骤的起止时间,协助学生同时进行多个挑战任务。各阶段的课程难度控制和教学节奏安排等教学设计过程是该教学模式的重点。最后根据教学评价和效果总结了该挑战性课程的教学经验。Challenging-based courses can improve students′initiative in many aspects,such as problem finding,independent learning,com-munication,expression and team management,which is a very important teaching method.Some applied courses have scattered knowledge points,which is almost impossible to adopt by a single challenge task to cover all the necessary knowledge points.Therefore,the challenging teaching mode of multi-objective and multi-stage is proposed to meet the actual requirements of course teaching.Taking the teaching practice of the challenge course"data security and forensics technology"as an example,expound on how to determine the challenge target and design the challenged content according to the knowledge points.In order to coordinate the implementation of multi-challenge tasks in teaching,after determining multiple challenge objectives,each challenge task will be divided into several stages and deployed in an imbricated manner.In the teaching process,it is necessary to design the start and end times of each step reasonably to assist students to carry out multiple challeng-ing tasks at the same time.The teaching design process of controlling course difficulty and arranging the rhythm of instruction is the key point of this model.Finally,the teaching experience of this challenging course is summarized according to teaching evaluation and effect.
