Herbart first proposed that pedagogy should become a science, and Comenius' great teaching theory marked that pedagogy became an independent discipline. The Great Teaching Theory written by Comenius in 1632 should mark the emergence of independent pedagogy. "An independent discipline begins to form" emphasizes that it is still in the "beginning" stage, so "grand teaching theory" should not be regarded as an independent discipline, it is just the beginning. "Becoming an independent discipline" emphasizes "becoming", so it refers to "General Pedagogy" written by Bert in 1806. In addition, it can be understood from the time that Herbart's "General Pedagogy" was later than Comenius's "Great Pedagogy" 174 years, which was relatively more mature and had a greater influence on the later.
