At that time, there were two opposing views: the substantive purpose and the formal purpose of teaching. The theory of substantive purpose holds that the main task of teaching is to impart knowledge and form skills. These two views hold their own opinions. The former shows enthusiasm for classical education and thinks that grammar, mathematics, logic and classical language play a great role in cultivating students' thinking ability. The latter shows the demand for modern education, and thinks that natural science, applied mathematics, geography and modern language are practical knowledge beneficial to students' lives.
