【摘要】 根据实践教学的要求,针对信号与系统课程数学依赖性强、概念抽象等教学特点,利用Matlab可视化工具对该课程的教学内容进行了分类可视化研究,提出了虚拟实验环境下的分类可视化教学方法,分析了一些可视化教学案例。该方法在虚拟实验环境下以问题、任务驱动为切入点,强化理论、突出实践,提供了一个具有直观性和自主性的学习环境,有助于学生利用可视化结果加强课程理论特性分析、总结应用规律,有利于培养学生实践能力,符合学生综合素质培养要求。更多还原

【Abstract】 Considering that this course has the strong dependence on mathematics and abstract concept,the authors introduce in this article a teaching mode which achieves classification and visualization of the teaching contents by using visual tool(MATLAB) at the request of teaching practice.In this paper,the classification schemes of visual simulations in virtual experiment environment designed for the teaching contents are described,and some visual simulations are illustrated.Driven by questions and tasks,this mode provides students with an intuitive and independent learning environment and helps them to stress the theoretical level and practical skills.It is shown that this mode will cultivate the practical ability of the students to apply visual results to understand the contents of course and summarize the law of application in practice,and raise their comprehensive quality.更多还原
