Abstract Taking “design solid hydrogen storage materials” as the learning context, the disciplinary value and practical application of electronegativity are well combined. Through the achievement of real problems and tasks, students are driven to experience the necessity of electronegativity, understand the concept and simple application of electronegativity, and use electronegativity to design hydrogen storage materials. This advanced deep learning process emphasizes the fundamental understanding of electronegativity, focuses on the microscopic essence, condenses the cognitive perspective with transfer value, and forms a structured approach to qualitatively and quantitatively measure the strength of atomic electron attraction ability. It enhances the disciplinary understanding of electronegativity, realizes deep learning, unleashes the educational value of disciplinary knowledge, and implements the disciplinary literacy of scientific attitude and social responsibility.
