以提高学生兴趣为导向的单片机实验课改革

Experiment teaching reform aimed at improving the interest of students

针对"单片机原理及应用"课程实验教学中实验内容陈旧、形式呆板,学生积极性不高的问题,对实验内容及教学方式进行了改革。改革以激发学生学习兴趣为导向,通过流水灯多样式设计改革I/O输出实验、步进电机控制改革定时器实验、PC机超级终端显示改革RS232通信、A/D转换实验等形式的实验内容的改革,大大提高了实验的趣味性及学生的积极性。改革中还注重强化学生使用单片机C51语言进行程序设计的能力,通过教师提供演示例程,学生分析理解例程后,扩展例程功能实现课程要求的形式进行教学方式改革。整个改革以提高学生整体水平为目标,同时设定少量较高设计目标,兼顾能力较强的学生的拔高培养,经实际验证获得了较好的教学效果。

Some problems are discovered in the experiment part of class ＂ Microcontroller Theory and Applications＂ for bachelors teaching, such as the content is timeworn, the teaching style is dry and the interesting of students is little. In this paper, some reforms are proposed, which is aimed at improving the students＂ interest. That＇s about changing the I/O output experiment with multi-style running lamps design, changing the timer experiment with step-motor controlling, and changing the RS232 communi- cation and ADC conversion experiment with displaying information on the hypertrm of Windows. The training about C51 programming skills is important part in this reform, some examples are provided them for analogy, and the more complex questions are asked to complete by kids. The aid of this re- form is to enhance the overall level of all students, and a little advanced task is prepared for the power- ful top students.
