School subjects are no longer valued on their own, but in close connection with each other: more and more attention is being paid to interdisciplinary connections. New demands are also being made on teachers: it is no longer enough for them to know only their subject; they must be aware of everything that is happening in related disciplines and be able to cooperate with colleagues to participate in joint projects. Many people liked working this way so much that they are ready to share their experience with teachers from other schools. Thus, on November 22, school No. 2065 held a Training Day at the IT training ground as part of the city IT marathon.
