Engineer pedagogics Building and Practice of BCD Teaching Mode Based on Scaffolding Instruction in Environmental Microbiology Experiment

The course of environmental microbiology experiment is featured as more knowledge points, difficult to remember, and has requirements for the students’ ability of experiment operating basic knowledge skills. Traditional infusion experimental teaching methods isolate the teaching content, and make students lack learning interest and the sense of responsibility, which are difficult to obtain satisfactory teaching effect. Therefore, stimulating learning enthusiasm and motivation, and enhancing the students’ autonomous learning ability and innovation consciousness is an important developing direction of the current teaching reform in colleges and universities. This study has focused on the environmental microbiology experiment teaching according to the theory of scaffolding instruction, the teaching reform was carried out, and a BCD mode has been designed and built, which has guided the students to actively participate in teaching, and promoted innovative consciousness and scientific research ability. In this study, teaching objectives have been realized.
