The book "Quality in Primary School Teaching" by Doris Drexl offers a comprehensive analysis of the collaboration between teachers and educators within the framework of the model project 'Bildungshaus 3 - 10'. It highlights how this cooperation influences lesson design and improves the quality of early education. Through the evaluation of interviews with teachers and an extensive observational study in nearly 60 primary schools, changes in attitudes towards lesson design and the consideration of children's individuality are addressed. The results show that significant improvements in various quality characteristics of teaching were observed in the model schools. This book is a valuable resource for anyone engaged with the quality of educational processes in primary education.
