Abstract In the teaching of “iron and its compounds”, the unit teaching of “iron salt and ferrous salt” was designed, with “exploring the chemical properties of ferrous sulfate” and “research on circuit board corrosion liquid” as the core tasks, combining iron salt with core knowledge such as the properties of ferrous salts and the mutual transformation of Fe2+ and Fe3+ runs through it, and establishes methods of thinking about the properties and transformation of materials from the perspective of material categories and element valences, and promotes the integration and development of multi-dimensional core literacy. After many rounds of teaching improvement, combined with the teaching practice process and its teaching effect, “focus on the application of inorganic matter understanding model, focus on the perspective and thinking of research materials”, “grasp typical activities, develop students' key competencies”, “design openness tasks, diagnosis through effective teacher-student dialogue, explicit problem-solving thinking” and other teaching strategies.
