TEE TEACBING OF ELEMENTARY PHYSICS 

 In Science for October 29, 1909, p. 578, 

 nine propositions were printed as the 

 basis for expected discussion at the next 

 meeting of the American Association for 

 the Advancement of Science. This discus- 

 sion occurred on Friday, December 31, 

 1909, and, though coming very late in the 

 week's program of the association, was 

 well attended. Section B, Physics, and 

 Section L, Education, met together for 

 this occasion. Vice-president Bauer, of 

 Section B, presiding. The previously an- 

 nounced speakers came forward in the fol- 

 lowing order: Professor Edwin H. Hall, 

 Harvard University; Professor John F. 

 Woodhull, Teachers College, Columbia 

 University; Mr. N. H. Black, Eoxbury 

 Latin School, Boston; Professor C. R. 

 Mann, Chicago University; Professor A. 

 G. Webster, Clark University. Several 

 others took part in the general debate 

 which followed. 



The substance of what I gave in opening 

 the discussion was placed before the meet- 

 ing in printed form and is reproduced be- 

 low under the heading "Comments on 

 Propositions 1-9." The only other formal 

 paper was the one read by Professor Wood- 

 hull, which was published in full in Sci- 

 ence, May 13, 1910. The only definite 

 proposition looking toward action by the 

 meeting in regard to the matter before 

 it was made by myself, to the effect that, 

 after debate, the meeting should vote 

 on the nine propositions which had been 

 printed in Science, in their original 

 form or as they might be amended, 

 and should transmit to the National
