inary report from the International Commis- 

 sion on the Teaching of Mathematics; and 

 Section B plans to devote one session to a dis- 

 cussion of the teaching of physics. The 

 Social Education Club, of Boston, plans to 

 hold one evening meeting with a program 

 that should be of particular interest. The 

 Eastern Association of Physics Teachers, the

 New England and the Association of Physics 

 Teachers of Washington expect to hold meet- 

 ings and render programs that will be val- 

 uable to those interested in educational 

 matters. 



The American Federation of Teachers of 

 the Mathematical and Natural Sciences will 

 hold its annual business meeting on Monday 

 afternoon. The American Nature Study So- 

 ciety will meet on Saturday morning to dis- 

 cuss the problem of physical nature study. 

 All of these meetings are open to the public.
