A study was conducted on the teaching reform of microcontroller technology courses in the context of vocational skills competitions,exploring how to improve students'skill level and professional literacy through curriculum reform.Firstly,the problems of the existing microcontroller technology curriculum were analyzed,including the excessively abstract teaching content,the disconnection between theoretical knowledge and practical ability,etc.Then,the reform ideas and methods were proposed.Specifically,by optimizing teaching content,improving teaching methods,and implementing competition training,students can better grasp the basic principles and application skills of microcontroller technology,enhance practical ability and innovative awareness,and cultivate professional literacy and teamwork spirit.Finally,through practical teaching,the effectiveness and feasibility of the curriculum reform were verified,and certain results and effects were achieved.The research results can provide reference and inspiration for teaching reform in other related fields.
