思维导图作为一种可视化图形思维工具，可以有效表征知识体系、层次关系。本文针对《微机原理及接口技术》课程教学现状，介绍了思维导图的特点，分析了思维导图应用于该课程教学中的作用和意义，给出了用 MindManager软件绘制的8086CPU内部结构和输入输出接口的思维导图案例。教学实践证明，思维导图在《微机原理及接口技术》课程教学中可以激发学生学习兴趣，帮助学生建立“整体-局部”思想，促进学生对知识的理解和记忆，提升教学效果。

As a visual graphical thinking tool, mind mapping can effectively represent the knowledge system and hierarchical relationship. In view of the current teaching situation of Microcomputer Principles and Interface Technology, this paper introduces the characteristics of mind map, analyzes the role and significance of mind map in the teaching of this course, and presents the inner structure of 8086 CPU and the mind map of input-output interface drawn by MindManager software. Teaching practice has proved that mind mapping can stimulate students' interest in learning in the course of Microcomputer Principles and Interface Technology, help students to establish "whole-part" thinking, promote students' understanding and memory of knowledge, and improve teaching effect.
