This article introduces an evaluation mechanism based on the BP neural network. It can help us better evaluate teaching effectiveness and potentially significantly influence teaching outcomes. We aim to enhance teaching efficacy and assist learners in improving their learning outcomes. Using MATLAB to assess the teaching efficiency of English classes, we found this approach eliminates the subjective influence of professionals and yields satisfactory conclusions applicable in various circumstances.
