| 英文摘要: |
| Molecular biology experiment training is essential for establishing the research ability. However, current teaching
methods mainly focus on the practical ability and neglect thinking ability. In this study, we discussed the application of PBL teaching
model in the biology experiment teaching by confirming that the idea "mutated beta-catenin promotes colorectal cancer cell proliferation".
Compared with the traditional method, in which DNA isolation, PCR, plasmid construction and purification, DNA electrophoresis, gel
extraction, protein isolation, western blot and transfection are taught separately, PBL teaching model combines these different techniques
to solve a scientific problem. The PBL teaching method delivered as much information as traditional method. In addition, the PBL
method stressed the connection among these different techniques and their putative implication in research. With the PBL teaching
method, the learning passion was greatly motivated. In summary, PBL teaching method significantly improves efficacy of teaching, which
would provide some clues for biology experiment teaching reform. |
