浅谈“三相异步电动机正反转控制线路”项目化实践教学

Project-based Practice Teaching of the Positive and Negative Control Circuit of Three-phase Asynchronous Motor

笔者结合近几年对"电气设备安装与维修"专业课的教学实践,探讨如何实施"三相异步电动机正反转控制线路"的实践教学,提出应在教学任务分析中注重知识的系统化,在方案设计中注重培养小组成员合作意识,在方案实施中注重培养学生解决问题的能力,在教学总结评价中注重提高学生学习效果,并通过项目完成评价表检验学生学习效果。指出实践教学的主旨是通过模拟企业真实的工作环境,让学生亲身参与到工作过程之中,学习和掌握与工作过程相关的知识和技能,学会从工作过程的全局出发分析、解决问题,从而获得与工作岗位更贴近的工作能力。

Based on the teaching practice of electrical equipment installation and maintenance in recent years,this paper discusses the practice teaching of positive and negative control circuit of three-phase asynchronous motor.It points out that some attention should be paid to the systematization of knowledge in the teaching task analysis,the training of team cooperation consciousness in the scheme design,the training of problem-solving skills in plan implementation,and the improvement of learning efficiency in teaching summary and evaluation,and the learning effect should be tested by evaluation form.The purpose of practice teaching is simulating the real working environment of enterprise to make students participate in the work process and master related knowledge and skills,so as to get the ability matching with the post.
