Based on his long practice and research, Mr. Ding Haochuan, the modern Chinese educator, attained remarkable achievement in education theory. His main ideas are as follows:1. Teaching is a noble profession. 2. The teachers should pay much attention to remoulding the souls of the students while play a leading role in teaching. 3. The teachers should do their utmost to integrate the teachers′ guiding function and the students' incentive. 4. Much attention must be paid to the school administration and the administrators in schools must be“experts” in administration. Although not perfect, his theory can be taken for our reference in the present day reform of teacher education.
