基于模拟仿真的单相全波整流实验教学探究

Exploration in One-Way Full-Wave Rectification Experiment Teaching Based on Analog Simulation

医学影像设备学、传统的实验箱教学普遍存在着很多问题,文章尝试采用较为常见的虚拟仿真软件进行改革与探索。参与者为已具备相关理论基础的大学四年级上学期(五年制)的医学影像学专业48名学生。让学生选择单相全波整流电路实验,构建模拟仿真电路,并与传统的实验箱教学进行对比。通过问卷星,从电路搭建、操作安全、参与程度、能力培养、学习兴趣、知识拓展等方面,对两种实验方法的教学效果进行了比较和分析。

There are many problems generally in the traditional experimental box teaching and Medical Imaging Equipment Science,and this paper uses the more common virtual simulation software for reform and exploration.The participants are 48 students majoring in medical imaging in the first semester of the fourth year(five-year program)of the university who has a relevant theoretical basis.Let the students choose one-way full-wave rectification circuit experiment,build the analog simulation circuit,and compare with the traditional experimental box teaching.Through the questionnaire star,the teaching effects of the two experimental methods are compared and analyzed from the aspects of circuit building,operation safety,participation degree,ability training,learning interest and knowledge expansion and so on.
