This book deals with the cultural and emotional world of Jewish schoolchildren in the “Tarbut” school network in Poland between the two World Wars. It is based on a unique corpus of about 80 letters, written between 1934-1935 by 10-11-year-old fifth graders in the Tarbut school in the town of Nowi Dwόr in Poland to their beloved teacher who had immigrated to Eretz Israel – the place and destination they too dreamed about. In these letters – all composed in Hebrew – the children write about their class, their school, but also about themselves and their families. The pupils’ letters are analyzed in light of the educational practice of pen-pal culture which was developed in and encouraged by “Tarbut” schools, especially between pupils in the Diaspora and their cohorts in Palestine. The letters are also examined as ego-documents that reveal personal stories about the intimate and private world of children, their experiences, fears and hopes, their relationship with their teacher, their families and their friends. Studied as a corpus, they reflect the complexities of the educational experience in a Hebrew Zionist school in Poland. The uniqueness of this book is that it is attentive to children – not teenagers or adults – in their own voice and in real time, telling about their lives, and not from a place of retrospection or later memory. Sources that allow us to hear the authentic voice of a child in real time are very rare indeed. The letters, which were critically edited and published in full next to a clear photograph of the letter, are discussed from various perspectives including Jewish, Hebrew and Zionist education, the history and culture of the child, and the relationship between the Diaspora and Eretz Israel. The book also offers a short history of the influential, now almost forgotten, school network – Tarbut. Finally, the book presents a detailed history of one class in one town in Poland a few years before this world vanished.
