Demonstration schools for rural communities have been organized with a view to showing the people in a definite and concrete way what a school can do for a community. These demonstration schools are usually placed in a central location and put under the charge of the teachers of greatest experience and ability. All of the children in the different grades included in the rural school course have a course of study to complete in the schoolroom, and another equally emphasized course of study to complete in the home and on the farm. Experiments and studies are being carried on which involve the use of every day throughout the year. To accomplish this end, the father and mother have become the assistant supervisors of the home work and the farm work, and they receive the advice, the suggestion, and the instruction of the rural supervisors of schools. While working to get the best possible results from the efforts made, and to establish the facts by samples, by photographs, and by financial relations of cost and return, these undertakings are accompanied by neighborhood meetings of many kinds which have had the effect of enlarging community interest, community support, and community improvement. Out of these efforts have come better social conditions, more harmonious relations, a development of better ideals, and a higher conception of life. These demonstration schools, in addition to being a force among the people in the community where they are located, also serve as educational centers which are to be visited by the other rural teachers of the community in order that the inexperienced and untrained teacher may receive the benefit of the teacher of more experience. In addition, these schools also serve the purpose of experimental schools where many ideas are worked out and put into effect, and new methods of teaching as well as untried methods of farming are given a trial. The rural school situation is being studied more to-day than ever before, for it is being realized that our country schools are not functioning to the best advantage. The social side of the task, extension work among the patrons of the district, consolidated and more efficient schools, and better trained teachers are only a few of the phases of this movement toward making the rural school a real force throughout the country. The movement is gaining ground each year, and though there are many problems to be solved and many difficult situations to be met, yet there is every reason to believe that out of this mass of experiments there will evolve the rural school of the future, which will be a more vital factor in the community than has been the case up to the present day.
