It was around that time that a new “child-centred” method of class teaching had come into being, namely, the oral question and answer. It was from Europe and was promoted by the famous Swiss educator, Johann H. Pestalozzi (1796 – 1827). Rev. Ryerson spread it through the province by way of his “Journal of Education”. Graduates demonstrated it at county conventions. Its success was made largely possible by the gradual adoption of uniform textbooks in the schools. The Pestalozzian method, no doubt, found its way to Oshawa, as was shown later in the public examinations.
