写作教学中的同伴互评模式一直备受推崇,国内外研究者对其作用褒贬不一。基于同伴互评的弊端,研究者们提出应对参与互评的学生进行系统的培训。然而,培训所有参与互评的学生既费时费力,又效果不佳。本文借鉴了美国大学培养同伴导师的方法,提出在国内培养及应用同伴导师以协助提高大学生英语写作水平。 Writing peer teaching peer assessment model has been highly respected, domestic and foreign researchers praised its role. Based on the shortcomings of mutual peer review, researchers proposed that systematic training should be conducted for students participating in peer reviews. However, training all students involved in peer reviews is time consuming and ineffective. This paper draws on the method of training peer mentors in American universities and proposes to train and use peer mentors in China to help improve college students’ English writing skills.
