The book "Discovering Learning in Mathematics Instruction for Students with Learning Disabilities" offers a comprehensive analysis of the ways in which children with learning disabilities can actively engage with learning content. It explores whether these children are merely capable of reproducing knowledge or if they can also learn through discovery-based learning. The author, Petra Scherer, draws on empirical studies and research findings from related disciplines to critically examine the current practices of mathematics instruction in schools for students with learning disabilities. The results are presented both quantitatively and qualitatively, providing valuable didactic implications. Additionally, a practical implementation of discovery-based learning is documented, which can help teachers develop a better understanding of their students' learning processes and leverage the potential of discovery-based learning.
