Construction of a Multi-Dimensional Evaluation System of English Online Learning Teaching Quality Based on Blended Learning

Blended online English learning has become a way to expand English outside the classroom. In the future, the blended learning approach allows students to learn English knowledge without the constraints of time, place and teacher subjects in traditional classroom teaching. However, there are still many problems in online English teaching in colleges and universities. The top three learning evaluation methods are: online exams, classroom assignments, and online answering tasks. Other learning evaluation methods are arranged in descending order. They are to evaluate their own English learning, to draw a conceptual map of learning knowledge, and to accept the teacher's opinion for advice. The performance of the three models has declined, and the performance of the online learning teaching model is still the highest among the three models. The accuracy of the online learning teaching model is 73.81%, indicating that the performance of online learning and teaching is the best.
