Abstract: Aiming at the problems existing in the current chemistry experiment teaching, based on the cultivation of students' application ability and innovative spirit, the experimental teaching system of "one body, two wings, three integration, four combination and five platforms" (12345) was constructed. Guided by the concept of OBE (Outcome based education), with the integration of science and education and the integration of production and education as the starting point, the experiment content was optimized, the experimental teaching model was innovated, the teaching methods and modes were reformed, the assessment and evaluation systems were explored. After 3 years of reform, a four-level, progressive experimental project system has been built, and a task-driven teaching model has been formed, which combines "virtual" and "real", design and innovative experiments, laboratory opening and scientific research, and online and offline teaching. Fruitful results have been achieved in the reform of experimental teaching, the construction of course materials and the training of high quality applied chemical talents.

Key words: Technological empowerment, Integration of production and education, 12345 Experimental teaching system, Applied chemistry talents, Three-dimensional evaluation system
