生医工专业嵌入式系统项目式教学改革与实践

嵌入式系统原理及实验是生物医学工程学科的核心专业课程。该课程的目标是以单片机为对象,通过基本理论学习、程序开发和硬件设计,使学生掌握嵌入式系统在测量与控制等相关领域的应用技能,为将来从事生物医学工程相关测控系统的开发打下基础。然而,传统的实验课程大纲主要面向泛工科体系下模块式实验教学案例而设计,存在如下局限性,一方面,无法深度锻炼学生的整体化项目开发思维和合作精神;另一方面,缺乏针对生物医学工程专业的特异性培养,使得学生的专业性体验不强。为此,该文以中山大学生物医学工程学院嵌入式系统原理及实验为例,对该课程进行项目式教学改革与实践。我们针对原本的模块化分立式实验,结合生医工专业应用需求,融合成综合实践课题项目,并通过分组对比的形式发现新型教学模式在提高学生主观接受程度、增强实验课掌握程度及促进理论课学习方面都具有明显提升。该课程的教学改革实践不仅增强学生对基础知识及应用实践关联性的理解,而且提高学生对嵌入式系统的综合应用创新能力,同时也加深学生的学科认同感和对学科前沿需求的了解,从而促进本科生高质量内涵式发展。

Embedded System Principle and Experiment is the core professional course of biomedical engineering.The goal of this course is to master the application skills of embedded systems in measurement and control and other related fields through basic theory learning,program development and hardware design,so as to lay a foundation for the development of measurement and control systems related to biomedical engineering in the future.However,the traditional experimental course outline is mainly designed for the modular experimental teaching cases under the pan-engineering system.There are the following limitations:on the one hand,it can not deeply train students'thinking and cooperative spirit of integrated project development;On the other hand,the lack of specific training for biomedical engineering makes the professional experience of students not strong.Therefore,this paper takes Embedded System Principle and Experiment of School of Biomedical Engineering of Sun Yat-sen University as an example to carry out the project teaching reform and practice of the course.Based on the original modular and discrete experiments,combined with the application needs of health and medical engineering,we integrated them into comprehensive practical projects.Through the form of grouping and comparison,we found that the new teaching mode had significant improvements in improving students'subjective acceptance,enhancing the mastery of experimental courses and promoting the learning of theoretical courses.The teaching reform practice of this course not only enhances students'understanding of the correlation between basic knowledge and applied practice,improves students'comprehensive application and innovation ability of embedded systems,but also deepens students'disciplinary identity and understanding of frontier demands of disciplines,thus promoting the high-quality and connotative development of undergraduates.
