Establishment of Caenorhabditis elegans-based Experimental Teaching System for Curriculum Chain of Ecological Environmental Health.

The field of ecological environment health is developing continuously in our country, and it has already formed a well-developed education system and curriculum chain. However, it still lacks an experimental teaching system in laboratories to match the theoretical education in classrooms. Such a lack brings challenges in educating professionals integrated with innovative spirits and practical abilities. Caenorhabditis elegans has solid biological background information and is a model organism in the fields of life science and ecological environmental health. An experimental teaching system is established with C. elegans in the present study. It includes preparation of culture medium, microscopic observation, individual development, reproduction, total protein contents, enzyme activities and also gene expression levels. The overall contents strongly match the theoretical contents in microbiology, biochemistry, environmental toxicology and ecological toxicology. The experimental teaching system can improve the students' capacities in practical operation and experimental design, which will pave ways for their innovative spirits and practical abilities to solve scientific problems in the future.
