“虚实结合”交互平台在“信号与系统”案例教学中的应用

Application of Interactive "Virtuality and Reality Combination" Platform in the "Signals and Systems" Case Teaching

高校《信号与系统》课程教学的实践环节目前采用的实践模式往往以强化理论知识为目的,该模式难以满足培养学生工程实践应用能力和创新意识的更高要求。针对该问题,提出了将"虚实结合"交互平台应用于"信号与系统"实践教学中的案例教学模式,并以"心率测量交互系统"为例介绍其设计、实现和应用的过程和方法。实践证明,通过融合"虚实结合"互动体验的案例教学模式,可以拓展学生思维,增加趣味性,促进研讨性学习,教学效果和学生的应用能力得到明显提升。

The practice mode of ＂ signal and system＂ course teaching currently tends to strengthen the knowledge. It is difficult to meet the higher requirements of training students’ application ability of engineering practice and innovative ability. Aiming at this problem,an interactive ＂ virtual and reality combination＂ platform is proposed and then applied to the case teaching of ＂ signals and systems＂. A teaching case of the ＂ heart rate measurement interactive system ＂ is introduced in detail. It is proved that the integration of interactive experience can stimulate students’ thinking,enhance their interest and promote research learning. The teaching effect and students’ ability of innovation and application are significantly enhanced.
