Ellwood Patterson Cubberley, The History of Education
“ The problem of education has had, with time, no such simple and easy solution. Instead, with the development of state school systems, the extension of education in many new directions to meet new needs, and the application to the study of education of the same scientific methods which have produced such results in other fields of human knowledge, we have come to-day to have hundreds of problems, many of which are complex and difficult and which influence deeply the welfare of society and the State. ”
