教学-实验-实训三位一体的单片机教学改革探讨

单片机及嵌入式课程在大部分高等学校理工科专业中处于重要地位,是大学生创新创业实践活动的重要工具。该类课程内容抽象难懂,和电路、数字电路、模拟电路、C语言等基础课关系较大,学生需要花费较长的时间进入状态,当动手实践课程较少时,知识点难以融会贯通。提出了一种集教学、实验及实训三位一体的教学实践方法,搭建多媒体教学平台,将教学与实践有机地统一起来,通过在线演示、分组讨论、小组实践、单独考核等环节有效地提高了学生学习的积极性和主动性,该方法先通过软件(Proteus+Keil)虚拟仿真,仿真正确后通过硬件验证,既有灵活快捷的优点,又节省了器件损耗。该教学方式灵活,考察方法多样,在实际教学活动中取得了较好的效果。

MCU and imbedded-chip education plays an important role in advanced education of most colleges and universities. MCU and imbedded-chip are the most important tools for students’ creative activities. These lessons are abstract and difficult to learn, and takes long time to enter the state of art for junior students. The knowledge has composed structure of several subjects such as digital electronic, analog electronic and electronic circuits. We proposed one method which combines teaching, experiments and practice of MCU. The method improves the effect of teaching and students’ learning enthusiasm. It is composed of the show-online, discussion in groups, practice and examination. Virtual simulation is proposed in software environment first and then verified on electronics hardware systems. It integrates the advantages of software and hardware of the virtual experiment training, flexible teaching methods, and achieves good result in practical teaching activities.
