Teachers, educators, or individuals working in the educational field face numerous challenges in their daily work life. In this book, the author focuses particularly on strengthening children's self-concept. Based on interviews with participants of a mentorship project (children and mentors), important insights into enhancing the various facets of children's self-concept are transferred from the 1:1 situation in the mentorship project to the 1:29 situation in a classroom. In conjunction with significant theoretical insights (self-concept research, educational style research, attachment theory, self-discrepancies), concrete, immediately applicable action alternatives in the school work routine with children are developed. These implications have been practically tested and enriched with case reports.
