Modern medicine is being transferring from traditional "empirical medicine" to more scientific "evidence-based medicine", which embodies the idea that clinical research is a primary motive that keeps medical practice continuously developing. Therefore, the contemporary aim of medical education should focus on attaching great importance to and strengthen the training of medical students' clinical scientific research ability. Based on clinical departments, we have built an open research project platform for volunteers for medical students before engaging in medical practice. Through a spirally-progressing teaching mode of "Training-Practice-Assessment-Retraining" for medical students before engaging in medical practice, the platform provides training on the knowledge and skills of evidence-based medicine and clinical scientific research. Through the volunteers' active and omnibearing practice, this project achieves some good outcomes in teaching and learning experience. This extracurricular teaching mode provides a platform for scientific research volunteers with the capacity for more knowledge before engaging in medical practice, which is recommended to empower the students with ability of scientific research.
