      Abstract:Listed as one of the five top-quality courses launched by Ministry of Education of China, virtual simulation experiment is an important measure to integrate the information technology into experimental teaching to improve the quality and level of experimental teaching, and plays an important role in cultivating the talents. Students-oriented teaching and learning with emphasis on interaction and engagement has been adopted to design the virtual experimental system with combination of real resources to aid mutually with advantages. The scientific research is introduced to demand-oriented and problem-based virtual experimental teaching. The modular, hierarchical and fragmented virtual simulation experimental teaching system of air conditioning system for deep underground space is developed based on cutting-edge research in the field of deep underground space air conditioning. The students will be able to implement the online virtual experiment anytime and anywhere with engaging experience, professional learning, interactive operation, and whole process assessment. It can make up for the shortage of traditional experiment apparatus, enrich the experimental teaching means and resources, enhance the students' innovative capability of solving the complex problem and improve the teaching quality.

      Abstract:Cementitious materials and concrete science is the core course of inorganic non-metallic materials engineering, which has strong comprehensiveness and professionalism. The course contains some in-depth theoretical knowledge, such as cement hydration, ion transport in nanopore, etc. Traditional teaching methods lack picture and video media resources, unable to vividly display the reaction process, which makes the teaching boring. This paper explores the introduction of molecular dynamics simulation into the course teaching, enriching the teaching content through the visualization results of simulation, giving students a perspective to observe the micro world, and materializing the abstract knowledge. The introduction of molecular dynamics has also brought about a change in teaching methods, which has stimulated students' interest in learning and achieved good teaching results.
