Education needs thinkers who work in the field of science and practice and strive for their synergy, and this is only possible when the platform for publishing the results of this scientific effort reaches the knowledge of experts and is exposed to criticism and discussion. Gird, the journal of research in multi-grade and integrated classes is a journal that tries to provide a platform for the concerns of education experts in relation to the topic of the journal and to facilitate the field of practice, its knowledge and content can be used as a program A scientific and complete book should be generously placed in the hands of the administrators and planners of education and through that channel, the issues and problems of education should be solved. On the eve of the publication of the third issue of this publication, I hope that thinkers and experts will pay attention to the articles and while studying and reviewing them, they will help this collection and help us in our mission.
