Abstract: The practical basis of electrical engineering is a new course initiated by integrating electrical engineering practice and cognitive practice. Aiming at the problems in the existing courses, the experimental courses are reformed and explored. Through the integration of “team cooperation + open source MCU + electronic technology” to design teaching content, reform the teaching strategy, and improve the teaching evaluation means, so as to achieve the purpose of training students’ engineering design ability, engineering operation ability, team cooperation ability. The scale of engineering practice ability was designed and the student experience was investigated. The results showed that the engineering practice ability of students was greatly improved and the teaching quality was significantly improved through the reform of the basic electrical engineering practice course.
