Exploration and Practice of the Mixed Experimental Teaching Mode of Online and Offline Based on OBE-CDIO Concept—A Case Study of Hydrogeochemistry Experiment Course
Hydrogeochemistry is a core discipline for hydrology and water resources engineering,groundwater science and engineering,environmental engineering and other related majors.Experimental classes are an important means of cultivating students'practical abilities,and their proportion has gradually increased after multiple curriculum reforms in recent years.In view of the shortcomings of traditional experimental teaching method,this paper proposes the mixed teaching mode of online and offline based on OBE-CDIO concept to explore and practice the experimental course of hydrogeochemistry.This teaching mode is aiming at improving teaching methods,diversifying experimental schemes and evaluating methods with students as the main body,so as to mobilize students'enthusiasm,cultivate students'creativity and ability to solve practical problems.The practical results show that the mixed teaching mode of online and offline based on the OBE-CDIO concept is very suitable for the development of students and can effectively improve the teaching effect of the experimental course of hydrogeochemistry.
