Abstract: Entering the era of artificial intelligence, the teaching model and evaluation methods of college English should also be innovated in line with The Times. Relying on advanced artificial intelligence technology, a college English classroom teaching evaluation system should be constructed. On the basis of selecting multi-dimensional teaching evaluation indicators and reasonably setting the weights of each indicator, intelligent perception technology should be utilized to monitor the entire teaching process. Collect students'facial expressions, eye movement data and behavioral postures in class, use intelligent algorithms to analyze students'learning behaviors and obtain the final evaluation results, providing assistance for the optimization of college English classroom teaching.
