There are many Olympic Mathematics training institutions in Nanjing, including learning and thinking, booksellers, Laoling, Shangbotang and other large institutions, as well as individual studios. The level of teachers is uneven, children have their own feelings, and parents have their own evaluations. Relatively speaking, the level of good teachers in large universities is still very high.
In particular, the level of teachers who graduated from the Department of Mathematics of Nanda Dongda University is significantly higher than other teachers. If they have just entered primary school, they are advised to sign up for classes and stick to it. Learning to think and write books is not only the teaching of Olympiad Mathematics, but also the focus of learning, which is very helpful for children to establish mathematics consciousness at an early age. If they can enhance their interest through a period of study, that is the best. In the future, whether it is school mathematics or real Olympics, children will be able to do it with ease.
Mr. Da Du and Mr. Xiao Du of Nanjing:
Among the 47 students who won the first prize in the fifth grade of the World Youth Championship, 40 were students of Mr. Dadu, and 20 students who won the first prize in the fourth grade were students of Mr. Dadu. Basically, there is no one in Nanjing who teaches elementary school olympiad but knows Mr. Du's reputation. More than half of the top students in Nanjing are from Mr. Du's school.
Teacher Du has a younger brother who also teaches Olympiad Mathematics. A set of teaching materials for two people is generally called big belly and small belly. The pot-bellied teacher is very kind to students and not good at communicating with parents. Teacher Xiao Du is not as strict as Teacher Da Du in selecting students, and parents are allowed to participate.
