ABSTRACT
The efficiency of any profession depends in large measure upon the degree to which it becomes scientific. The profession of teaching will improve (I) in proportion as its members direct their daily work by the scientific spirit and methods, that is by honest, open-minded consideration of facts, by freedom from superstitions, fancies or unverified ‘guesses, 1 and (2) in proportion as the leaders in education direct their choices of methods by the resujts of scientific investigation rather than by general opinion.
