In the context of the 4.0 industrial revolution, STEM education is not only a trend but also an urgent requirement to train high-quality human resources to meet the country's development needs. To equip students with the necessary knowledge and skills in an interdisciplinary manner (Science, Engineering, Technology, Math), the STEM education model has been widely applied in schools. This article studies the application of the STEM education model in teaching the topic "Introduction to electronics" in the 11th-grade Physics program, specifically through model design orientation: Automatic rain cover helps Develop students' practical problem-solving capacity.In the context of the 4.0 industrial revolution, STEM education is not only a trend but also an urgent requirement to train high-quality human resources to meet the country's development needs.
