The book "Further Training on Dealing with Mathematical Difficulties in Schools" by Svenja Lesemann offers a comprehensive analysis of a one-year training program designed to support teachers in addressing mathematical difficulties. The author combines theoretical foundations with practical applications to identify effective support options for educators. Through interviews, questionnaires, and classroom observations, the effectiveness of the training is examined at both the teacher and student levels. Changes in teachers' knowledge about mathematical difficulties and the impact on students' performance in learning mathematics are considered. This book is a valuable resource for anyone involved in supporting students with mathematical difficulties.
