This study delves into the strategies of teaching narrative text reading in higher grades of primary school under the Unified Edition Chinese Textbook, guided by the concept of Learning Task Groups. The concept, a novel educational approach, emphasizes designing a series of interconnected, progressively deepening learning tasks to stimulate students' interest in learning and foster their comprehensive thinking and learning abilities. Through methods such as questionnaires, interviews, and classroom observations, the study comprehensively analyzes the current state of narrative text reading instruction in higher grades. It highlights the challenges faced by teachers in designing and implementing learning tasks and proposes targeted improvement strategies. The implementation of the Learning Task Groups concept, as evidenced by specific case studies and practices, has been shown to effectively enhance students' reading comprehension, language expression, and innovative and critical thinking abilities. Despite challenges like limited resources and individual differences among students, the study suggests that enhancing teachers' professional capabilities and optimizing educational resources can further promote the effectiveness of teaching strategies. Finally, the paper provides comprehensive suggestions for education policymakers, educators, and frontline teachers, emphasizing the need to focus on the holistic development of students, advocating innovative teaching methods, and improve the quality of education to nurture well-rounded individuals equipped with critical thinking, innovative capabilities, and a sense of social responsibility.
