The educational and teaching activities of the Sisters of the Resurrection in the interwar period were rich and diverse. The sisters organized work at various educational levels, from preschool children, through primary and secondary schools, to students. They ran private kindergartens in seven towns: Warsaw, Częstochowa, Poznań, Kęty, Grudziądz and Rumia-Zagórze. They ran seven-grade primary schools (level III) in five towns, i.e.: Warsaw, Częstochowa, Wejherowo, Poznań, Mocarzewo. Primary schools in Warsaw, Częstochowa and Wejherowo were merged with secondary schools. In addition, the sisters ran a teachers' college in Warsaw. In addition to the schools mentioned above, the sisters organized schools and technical courses. In Częstochowa, they ran secondary technical schools: first a seven-grade production and trade school, then a four-year mercantile middle school and a two-year commercial high school. They ran housewives' schools (first level) in Poznań, Brusy and Stryszawa. In addition, they organized technical courses for girls and women, especially in villages: cutting and tailoring, handicraft, knitting, housekeeping, cooking, etc. The sisters paid particular attention to their work in boarding schools, which they opened in towns where their Order ran daily schools. They also ran boarding schools for girls attending other public or private schools, for female students and for young professional women. When organizing after-school activities, the sisters gave priority to rural communities. They ran community centers for children and provided work for poor village girls in sowing. They attached particular importance to catechesis in the parish. An important form of activity was also the teaching and educational work of the sisters for the homeless and unemployed. They organized cultural and educational activities of this social group in two centers: in Warsaw and Grudziądz. Forms of teaching and educational work also include holiday camps for children and teenagers. Summer camps were held mainly in towns where the sisters' houses were located. In addition to the above-mentioned forms of work, the sisters were also involved in writing. Their work was addressed to parents and teachers on the one hand, and to children and young people on the other. The written output of the first generation of the Sisters of the Resurrection included treatises, articles and reflections on the goals, tasks and methods of education, especially national and religious education. The authors of the educational works were: T. Kalkstein, A. Kossowska and B. Żulińska. The richest contribution to pedagogical writing was made by B. Żulińska. The forms of work presented above may lead to the conclusion that the sisters of the Order of the Resurrection made a huge contribution to the development of the cultural and religious life of Polish society in the period between the two World Wars.
