Abstract： Clinical educational reflection is one reflecting in clinical education settings. Once clinical educational reflection ability enhanced, deeper inspection and exploration through certain educational experience can be expected, furthermore, clinical education quality will be more likely to be improved. A clinical educational reflection training experiment was implemented among the head nursing preceptors of the Third Affiliated Hospital of Southern Medical University, of which the process of training design and steps were elaborated. Educational reflectional diaries, questionnaires and group-focused semi-structure interviews were applied to analyze the training effect. It was shown that not only the training was approved by the head nursing preceptors, but also the ability of their clinical educational reflection was indeed improved after training.
