Abstract: With the increasing popularity of online teaching, online teaching has been vigorously promoted, and classroom teaching is no longer only conducted offline. There is a prominent contradiction between students’learning and work in open education, and the blended teaching model combining online and offline modes can break the constraints of time and space, making it easier for students and teachers to accept. In order to more accurately evaluate the teaching effectiveness of blended learning mode, the article introduces the Kirkpatrick four level model, which plays an important role in the field of evaluation. The experiment compares the Coriolis model with the Analytic Hierarchy Process (AHP) model commonly used in evaluation. The results show that the weights of various indicators in the Koch model and AHP model in the mixed teaching effectiveness evaluation system are quite close, and the Koch model has a high credibility of teaching effectiveness. Compared with the AHP model, the Koch model is clearer and simpler.
