Self-evaluation and peer-evaluation of English writing were conducted online,and the results were recorded as multilevel digital portfolios on a newly constructed WebDAV system.MAHARA was also introduced as a system to search and view the portfolios effectively. In the descriptions of the portfolios, time-series changes and relationships in strategies, collaborative metacognition, self-efficacy were analyzed by employing text mining and case study as a qualitative research method. The study also quantitatively examined the improvement of strategy use and self-efficacy, based on questionnaires and the development of writing performance with the Coh-Metrix program.It finally elucidated the effectiveness of the multilevel portfolios in the support of autonomous collaborative learning of writing at university in conjunction with qualitative research.

在线进行英语写作的自评和互评，并将结果记录为多层次的数字档案，并引入MAHARA系统进行有效的检索和浏览。在档案袋的描述中，采用文本挖掘和个案研究的定性研究方法，分析了策略、协作元认知和自我效能感的时间序列变化及其关系。本研究还通过问卷调查和Coh-Meidler写作成绩测试，定量分析了策略使用和自我效能的提高，并结合质性研究，阐明了多层次档案袋在大学英语写作自主合作学习中的有效性。
