I have had an inquiry (on EH.Net's ASK THE PROF service) from an educational  
researcher asking two questions:  
 
1) Does anyone know when economics was first introduced into the school  
curriculum (K-12, not university) in the United States? NOTE: My  
conversation with the researcher suggested that this question was not  
limited to mid- to late- twentieth century (successful) efforts to  
incorporate a course in economics to the high school curriculum in many  
states.  
 
2) What textbooks or readings might have been used in K-12 courses? NOTE:  
Again, conversation with the researcher indicates that this question could  
be extended to include economics readings assigned in a civics course, etc.,  
not just what economics texts were assigned in the newly created economics  
courses.  
 
Help identifying resources which would assist with the answers to these  
questions would be appreciated.
