The book "Grammar in English Teaching at the Primary Level" offers a thorough examination of the role of grammar in English instruction for children aged eight to ten. It demonstrates that the widespread assumption that children cannot process grammatical structures is unfounded. Instead, it argues that the integration of grammar into teaching is crucial for the linguistic development and productivity of learners. Based on current research findings from language acquisition studies, learning and developmental psychology, and subject didactics, practical teaching suggestions are presented. These suggestions aim to create an action-oriented and child-friendly classroom that enhances students' grammatical skills and leads to better learning outcomes. The book is a valuable resource for teachers who recognize and wish to implement the importance of grammar in English instruction.
