Objective　To explore the effect of E-learning platform on nursing undergraduates' self-learning competencies of fundamental nursing course. Method　176 nursing undergraduates in their second year were included in the study

and investigation about self-learning competencies was carried out before and after the E-learning platform applying in the fundamental nursing course and the use condition was investigated after its usage. Paired t-test was used to compare the scores of self-rating scale for self-directedness in learning (SRSSDL)

Wilcoxon rank sum test was used to compare the examination scores level

and the use condition was analyzed by descriptive statistics. Results　Ex-cept learning strategies

after the application of E-learning

SRSSDL score of each dimension and the total score were significantly higher than that before application(P<0.05)

and the total score was improved (5.6±23.0)

(P=0.002). The examination scores was significantly increased than that of the before (P<0.01)

the rate of excellent and good was improved 24.54%. more than 90% of the students thought that E-learning could meet their learning needs and improve the learning ability. Conclusion The nursing undergraduates' self-learning competencies of fundamental nursing course and the scores can be significantly improved by applying E-learning course platform. But more efforts are needed to make its effect maximized.
