To solve the problems in teaching of electrontechnics and electronics experiments，the course teaching research group integrates“student-centered”teaching method into project-based teaching，the reform is implemented by systematic design of experimental contents，project-based teaching of experimental tasks，and evolutionary design of functional circuits．It takes the application circuit of integrated operational amplifier as an example，combine the project-based teaching method with electrontechnics ＆ electronics experiments teaching method，to discuss the whole process of effectively guiding students to design the unit circuit and system circuit independently，simulate design verification，assembly and test the circuits．In this way，we hope to cultivate students’experimental and engineering design ability，promote students’innovative thinking and problem solving ability．Finally，it effectively improves the quality of electrontechnics ＆ electronics experiments course

teaching，and it will also provide an innovative example for the teaching reform under the background of emerging engineering education．
