Research on the Application of PBL Mode in Inorganic Chemistry Teaching: Case Analysis of Practical Teaching of Nitrogen Elements Based on Mind Maps

Abstract

Project-based learning (PBL) is gradually gaining attention as an effective teaching method with the deepening of educational reform. The combination of thinking maps and PBL teaching mode is applied to the teaching process of nitrogen group elements, which effectively promotes the improvement of chemistry students' comprehensive skills such as creative thinking and problem solving. Students completed the PBL pre-study task list before class, and in class, teachers and students worked together to achieve the teaching objectives using the mind mapping tool. Through this new teaching model, students are able to gain a deeper understanding of the scientific principles of the nitrogen group of elements and apply what they have learned to practical problem solving. Teachers play the role of guide in this process, providing the necessary support and feedback to help students grow in their exploration. Compared with the traditional teaching mode of elementary compounds, this new teaching mode creates a more active classroom atmosphere, which fully embodies the effective teaching concept of "students as the main body, teacher as the guide".
