"A century-long plan, education-oriented." Education is the foundation of the development of human society, and teaching is the only way to implement education. The central work of the school is teaching, and the quality of teaching is the basic index to measure the work of the school, which is related to the future and destiny of the school. To strengthen college education, the most fundamental thing is to do a good job in teaching and improve the quality of classroom teaching. The quality of classroom teaching is a sign to measure a teacher's level. In order to achieve the best possible teaching effect in the limited classroom time, teachers need to fully adopt reasonable and effective teaching methods to mobilize students' enthusiasm and initiative in learning and stimulate their enthusiasm for learning. In addition, teachers' own quality and teaching attitude are also indispensable factors to stimulate students' interest in learning and improve teaching quality. After years of teaching practice, the author believes that to improve the teaching quality, we need to pay attention to the following aspects: clear classroom teaching objectives, careful preparation of lessons, self-improvement, and flexible use of teaching methods. Here are four ways to improve the quality of college classroom teaching. First, clear classroom teaching objectives. Teaching objectives have the function of guiding, encouraging and evaluating the whole teaching process. The success or failure of teaching depends largely on whether the teaching objectives are accurate, specific and comprehensive, and whether the requirements are appropriate. Therefore, teachers should set clear teaching objectives for each class and chapter, and specify what knowledge students are required to master.
