The subject of one-room schools has been increasing in popularity in recent years. These school are also known as country schools, rural schools, and, by the federal government, as one-teacher schools. If you are interested, you should know about the following sources.
The Country School Association of America hosts an annual conference each year where people present the latest research in country schools. Visit their website here: http://www.countryschoolassociation.org/
The official CSAA listserv is aimed at one-room school museums, researchers, and people who are interested in the history of one-room schools. People involved with active one-room schools or the small school movement also are welcome. You can preview and join their official electronic e-mail list at: http://groups.yahoo.com/group/oneroom/ Once you are a member you also get access to the many resources and links that are blocked when you just preview. You don't have to officially join the organization to join the listserv. I currently serve as listmistress.
As they have not corrected updated information as I forwarded it on, I have mirrored the information here with updates as I get them. The Iowa Historic Preservation Alliance list is broken into three parts and may be easier to load for those with slower connections.Click on Iowa's One-Rooms in the drop down menu above. If you would like to correct information or add your one-room school museum to the list, the survey form is on the Lunch Survey page. http://www.trundlebedtales.com/iowas-one-room-school-museums.html
