THE ORDINATION OF SCIENCES IN EDUCATION. 



BY R. I. RAYMOND, UNIVERSITY OF THE SOUTH. 



(A hstract.) 

 An outline of the relation of scientific information to education 

 in general, and a suggested optimum arrangement of the several 

 sciences in the educational plan. 



1. The relation of the sciences to education as a whole. Need of 

 factual information as distinguished from the process of mind-

2. The place of the sciences in educational evaluation with refer-

3. The order of the sciences in the scholastic scheme. 



4. The essentials of each science in an ideal presentation, as dis- 

 tinguished from the commonly taught "available data and experi- 

 mentation." 



5. What may be expected from a broad scientific education as a 

 full justification of its establishment in common schools.
