基于OBE-CDIO模式的《数字电子技术》课程改革研究

Research on the Reform of Digital Electronic Technology Course Based on OBE-CDIO

传统的课程教学存在种种弊端,效果欠佳,《数字电子技术》课程改革势在必行。基于学习成果为导向的OBE教育理念,按照CDIO工程教育的方式指导课程改革:在教学方法上,采用项目化教学,教师将对应项目布置给学生,要求学生在学习过程中,思考用哪些知识可以来完成该项目,知识学习结束后,引导学生梳理知识体系,讨论项目可能的解决方案,请学生完成具体的实现过程;在教学方式上,将课程中需要理解和记忆的每个基本知识点在备课时录制为3-8min的短视频,借助于超星学习通将其作为课前预习的任务点,将学习过程扩展到课堂之外,课上完成知识点的总结、测验,重、难点的讨论,实现深层学习,课后学生完成课堂总结、作业;在实验课教学中,将操作、实践能力作为导向,每堂课的前15分钟内对上次实验任务完成情况的考察;最后,构建课程新的评价体系,将课前-课中-课后学习的全过程量化管理,作为课程评价的重要部分,引导学生,学习要在过程中进行,而非考前去死记硬背。

There are many disadvantages in the traditional curriculum teaching and the effect is not good,so the reform of curriculum of Digital Elec⁃tronic Technology is imperative.Based on the OBE education concept,the curriculum reform is guided by the way of CDIO engineering ed⁃ucation.In terms of teaching methods,using project-based teaching,teachers will assign corresponding projects to students,requiring stu⁃dents to think about what knowledge can be used to complete the project in the learning process.After the completion of knowledge learn⁃ing,guide students to sort out the knowledge system,discuss possible solutions to the project.Students were asked to complete the specific implementation process.In terms of teaching methods,each basic knowledge point that needs to be understood and memorized in the course is recorded in a short video for 3-8 minutes during the preparation period.With the help of the platform of Chaoxing software,it is regarded as the task point of pre-class preparation,and the learning process is extended to the outside of the classroom.Deep learning is re⁃alized in class,in the way of completing the summary and test of knowledge points and discussing the important and difficult points.After class,the students finish the class summary and homework.In the experiment teaching,the ability of operation and practice is taken as the guidance,and the last experiment task is inspected in the first 15 minutes of each class.Finally,a new curriculum evaluation system is con⁃structed to quantify the whole process of pre-class,in-class and after-class learning as an important part of curriculum evaluation.It guides students to learn in the process,rather than memorizing before the exam.
