Abstract: This paper introduces the design concept and basic structure of the modular teaching microplasma atomic emission spectrometer, using it as an example to demonstrate teaching reform strategies. The self-constructed device experimental teaching model enhances students’ understanding of fundamental principles while improving their hands-on skills and innovative abilities. By incorporating 3D printing and AI technologies, the approach aims to enhance teaching efficiency and equip students with the skills to apply advanced technologies. The modular teaching method allows students to choose study content based on their interests, supporting personalized learning experiences and fostering comprehensive analytical abilities and creative thinking.

Key words: Instrumental analysis experiment, Teaching microplasma atomic emission spectrometer, Self-constructed device, Innovation and creativity
