在现代社会信息化、数字化、万物互联的大背景下,传统的教学方式很难达到理想的教学效果.针对"单片机原理与应用"课程信息量大、抽象难懂、学时少、实践能力要求高等问题,文章提出了一种基于PBL(Problem Based Logic)贯穿式项目的三级分类培养仿真教学法,将物料计数器作为贯穿式项目融入所有章节的学习,以问题为导向将其分为基础功能(一级)、扩展功能(二级)和创新功能(三级)并以教师仿真演示为辅、学生仿真实操为主进行项目练习.同时,对课堂教学设计、实施手段、考核方式等方面也进行了改革.实践结果表明,该方法激发了学生对前期理论知识的学习热情,对学生快速上手、入门单片机,增强动手实践能力具有重要的作用.
Research and reform on the teaching of"Microcontroller Principles and Applications"course:three level classification training simulation teaching method based on continuous projects
In the context of modern society's informatization,digitization,and the interconnection of all things,traditional teaching methods are difficult to achieve ideal teaching results.This article proposes a three-level classification training simulation teaching method based on Problem Based Logic(PBL)continuous project to address the problems of large amount of information,abstract and difficult to understand,few class hours,and high practical ability requirements in the course of"Microcontroller Principles and Applications".The material counter is integrated into all chapters of the learning as a continuous project,and is divided into basic functions(level 1),extended functions(level 2),and innovative functions(level 3)with a problem oriented approach.The project practice is supplemented by teacher simulation demonstrations and student simulation practical operations.At the same time,reforms have been made in classroom teaching design,implementation methods,assessment methods,and other aspects.The practical results show that this method has stimulated students'enthusiasm for learning theoretical knowledge in the early stage,played an important role in quickly getting started with microcontrollers,and enhancing their hands-on practical abilities.
