1, facing the pressure of teaching evaluation: the teaching evaluation results of university teachers have a great influence on their career development. Too many students fail in a class, and the teacher's teaching evaluation score is low, which affects his career promotion and salary. This will make teachers face greater pressure of teaching evaluation and affect their teaching quality and enthusiasm.
2. Need extra tutoring for students who fail: If there are too many students who fail in a class, teachers need to spend more time and energy tutoring these students to help them pass the exam. This will increase the workload of teachers and have a certain impact on their work and life.
