I am happy to greet you again and introduce a new journal issue which is mostly devoted to a popular and widely used Russian concept of school holistic systems. The foundations of this concept were created by famous Russian educators Alexander Kurakin, Ludmilla Nowikova and Vladimir Karakovsky and are well developed by the Center of Theory of Education, Institute of Theory and History of Education, Russian Academy of Education (RAE), headed by an Associate member of the RAE, Dr. Natalia Selivanova. Due to the Center's tremendous work and activities, numerous publications, conferences and seminars, the idea of school holistic systems became widely known and largely accepted by the educational community all over the country.
