SOCIETIES AND ACADEMIES. 



THE MISSOURI SOCIETY OF TEACHERS OF 

 MATHEMATICS. 



The past few years has been a very wide- 

 spread movement among teachers of mathe- 

 matics towards the organization of local, state 

 and sectional associations of teachers of 

 mathematics. This movement is both a re- 



sult and a cause of a very general dissatisfac- 

 tion with methods of teaching mathematics 

 in the recent past, and of various kinds of at- 

 tempts to improve them. Among the many 

 ideas that are prominently discussed are those 

 suggested by the terms correlation, laboratory 

 methods, individual instruction, self-activity, 

 graphical methods, etc. The facts of modern 

 life are furnishing material which is replacing 

 obsolete problems. An effort is being made 

 to bring mathematics into vital relations with 

 the whole of life. Even the long undisturbed 

 supremacy of the methods of Euclid in sec- 

 ondary education is being questioned. What 

 will it lead to ? Even the elementary teacher 

 can not fail to see what the investigator has 

 never lost sight of, that he is dealing not 

 with a completed, a dead, a petrified subject, 

 but with one of the most vigorous, living, 

 growing subjects taught in our schools. Per- 

 haps one of the strongest evidences that this 

 is the case is seen in the large number of 

 state and sectional organizations of teachers 

 of mathematics throughout the country. 



The first annual meeting of the Missouri 

 Society of Teachers of Mathematics met at 

 Columbia, Missouri, May 6, 1905. A prelim- 

 inary meeting had been held at St. Louis in 

 connection with the National Educational 

 Association. The temporary organization pf 

 the society was effected at the meeting of the 

 State Teachers' Association at Columbia, De- 

 cember 28, 1904. At a meeting of the mathe- 

 matics section of that body a committee of 

 organization was appointed, consisting of E. 

 E. Hedrick, University of Missouri, Colum- 

 bia; H. C. Harvey, State Normal School, 

 Kirksville, and B. T. Chace, Manual Training 

 High School, Kansas City. 



The permanent organization was completed 

 at the meeting on May 6. The constitution 

 provides that there shall be at least two meet- 

 ings each year, one in connection with the 

 annual meeting of the State Teachers' Asso- 

 ciation, the next meeting of which will be 

 held at Jefferson City, December 1905, and 

 one during the month of April or May, which 

 shall be the annual meeting for the election 

 of officers and the transaction of general busi-
