First, we should reflect on our professional ethics. Whether teachers are loyal to their duties, unite and cooperate determines whether they can teach and educate people dutifully, whether they are down-to-earth, keep forging ahead, whether they are diligent and eager to learn and teach scientifically, which all affect the development and improvement of teachers' educational ability and level. Therefore, teachers should have good political and ideological quality and noble professional ethics, have a high sense of responsibility and mission for the fate and future of the motherland, have a deep understanding of the nature, responsibilities and characteristics of teachers' work, have selfless dedication of "dedication", "responsibility", "enterprising" and "love for the cause" and "love for students", and have the dedication to work hard for the development of education. Second, we should reflect on our own educational and teaching ideas. Teachers should establish a correct concept of education and teaching in line with the development of the times. In education and teaching, we should focus on students' development, highlight students' subjectivity and cultivate students' autonomous learning ability; Attach importance to the cultivation of students' basic concepts, thinking skills and practical ability; Help students master knowledge, learn to apply knowledge and skills to solve practical problems, improve students' scientific and technological literacy, and effectively promote the all-round development of students' learning and personality. Third, we should reflect on our own teaching practice. It is always possible for people to reflect on themselves and their own practices. We keep a distance from our own practice in order to better understand and be familiar with it. In my opinion, teachers should constantly reflect on their teaching activities in order to realize the rationality of teaching practice. When thinking about their specific teaching activities, teachers try to find scientific teaching methods and form their own unique teaching style. Fourth, they should reflect on their own knowledge system. Although teachers have gained some professional knowledge and skills in college, a lot of necessary knowledge still comes from their own teaching practice and self-reflection. In order to ensure the rationality of knowledge and the effectiveness of practice, teachers must constantly reflect on their own knowledge system, eliminate their misunderstandings and prejudices in knowledge, and enhance their insight and understanding of educational practice and its complex situation. Fifth, we should reflect on our teaching and scientific research ability. Teachers should have outstanding experimental ability of teaching reform, dare to put forward their own solutions to new educational phenomena and problems in combination with their own work, and dare to improve their educational ideas through continuous practice. Therefore, teachers should constantly reflect on their teaching and scientific research ability and strive to be expert teachers. Sixth, we should reflect on our own teaching routines. Every teacher should always reflect deeply on his teaching habits, so as to overcome the blindness in teaching and promote the continuous improvement and perfection of his teaching skills. Therefore, it is a safe and effective way for teachers to reflect on the teaching routine, take its essence and innovate. Seven, we should reflect on the teaching content. Textbooks are compiled by educational experts and scholars and are the basic basis of teaching. However, the teaching materials will also have shortcomings. Therefore, teachers should take the teaching materials as the objects that need to be processed and reformed, scientifically adjust the contents and data of the teaching materials according to the local social life reality and students' existing life experience and cognitive level, creatively use the teaching materials, and make records in time to provide a basis for improving teaching. Eight, we should reflect on whether the function of moral education is realized. As far as the particularity of ideological education is concerned, the function of moral education cannot be missing. Ideological and political lessons should not only impart knowledge, but also guide and educate students' bad emotions, inner contradictions and vague thoughts. Teachers should seize the educational events in time to educate students and implement the moral education function of ideological and political courses, and should not miss the good opportunity. Nine, we should reflect on our physical and mental health, which is the material basis for teachers' development. Without a healthy body, it is difficult to ensure the completion of education, teaching and scientific research tasks. Healthy personality is a powerful means of education, which has a direct impact on students' ideals, beliefs, values, interests, hobbies and personality. Therefore, teachers should always reflect on their physical and mental health. To sum up, teaching reflection is a conscious activity and process for teachers to critically examine their own teaching behavior and the experience, ideas and background on which they are based, sum up success or failure, constantly optimize teaching problem solutions, and strive to improve the rationality of teaching practice with the help of action research, which will play a good role in guiding and promoting future education and teaching.
