针对微机原理与单片机技术课程理论教学课时紧张、内容多、难度高以及实践教学方式僵化的问题，提出将理论与实践教学融合贯通为一个整体进行课程设计的教学理念，阐述如何应用不同层次的实践教学作为不同难度教学目标的实现手段，构建基于工程素养和能力培养的渐进式教学模式，介绍师生共评的教学评价改革措施，说明教学成效。

Addressing the difficulties of “the principle of microcomputer and microcontroller” course,such as more and complicated content, less theoretical teaching hours, rigid practical teaching model.This article proposes a teaching philosophy that integrates theoretical and practical teaching into a unified whole for curriculum design, elaborates on how to apply different levels of practical teaching as a method to achieve teaching objectives of varying difficulty levels, constructs a progressive teaching model based on engineering literacy and ability cultivation, introduces teaching evaluation reform methods involving joint evaluation by teachers and students, and explains the effectiveness of the teaching approach.
