With the development of internet technology, a large number of intelligent network teaching platforms have been introduced into foreign language teaching process, which has a significant impact on teachers' teaching conceptions and methods and students' learning styles. Through questionnaires and data analyses of 80 non-English majors, we attempt to understand the development of a multidimensional dynamic evaluation system based on Fif teaching evaluation system, as well as the intervention effect and improvement measures on the affective factors of non-English majors in their language acquisition. The results show that the implementation of the teaching evaluation model has a positive role in promoting students' attitude, confidence, learning style and cooperative ability in language learning, whereas the setting of evaluation criteria and evaluation indicators needs to be improved.
