Material analysis problem

1. Professor Luo found that students can solve problems in different ways when correcting their homework. Most of them used the total score method and decimal method to solve the problem, but due to carelessness, several of them made mistakes. Teacher Luo wrote in her exercise book: "Decimal system is good! I wish I could be more careful. A few people used the methods of drawing and estimating, all of which were correct, and so was Macey, but the picture was not standardized. Teacher Luo wrote in her exercise book: the handwriting is delicate and the pages are neat. If only the pictures of cakes were standardized. I also found a "special case", Xiao Tao, whose math score is not ideal. When comparing the scores of 45 and 2 13, I used the isomorphic method, so I wrote in my exercise book: The solution is unique, and I hope to keep flashing the spark of wisdom. The next day, in class, Mr. Luo commented and explained. After getting the exercise book, Xiao Tao was very happy to see the comments and took the initiative to find the teacher. Teacher Luo once again affirmed his willingness to think. Xiao Tao gradually became interested in mathematics, listened carefully in class, finished his homework on time and became a representative of mathematics class. Question: Please evaluate the educational behavior of Teacher Luo Lao L from the students' point of view. (14)

2. Letter from students who have graduated for many years to the teacher: In the first to third grades of primary school, the teacher was full of poor students and the seats were arranged in the corner. Teachers don't ask questions. Good students don't play with me, only naughty students play with me. In the fourth grade, you became my head teacher and stared at me from time to time. Although it was only a moment, it made me feel a kind of warmth that I had never felt before. One day, I was called to the office and sat in a chair. I was shocked by my pet and told me that you need four flag bearers to raise the flag. You are tall and fit, so take it seriously. A warm current suddenly surged in my heart. On the day of flag-raising, teachers and students attracted much attention, and a sense of happiness came into being. I swear I won't fool around again, and I will repay you well, so I listened carefully, and you kept encouraging me to contact my parents, so my study was on the right track. Thank you very much. The experience of the flag bearer gave me warmth and confidence, which benefited me for life. Question: Please evaluate the teachers' educational behavior in the materials from the perspective of teachers' professional ethics. (14)
