This ethnographic case-study examines the impact of asynchronous written feedback comments on the peer feedback process within one doctorate writing group. The doctorate students were interviewed retrospectively about their perceptions of effective feedback comments. Affective components (e.g. hedging devices) and effective components (e.g. revision comments) within the reviewers’ feedback comments, and external components (e.g. reviewer competency) that influence the peer feedback process were induced from the interview transcripts using a grounded theory approach. Further evidence that these identified components impact the feedback process appreciably was triangulated from the analysis of two other datasets; the participants’ asynchronous written feedback comments and revision plans. The results show that the participants used much affect in their written feedback exchanges, and this affect had a strong impact on the effect of their feedback process. Thus, written affective language can play a significant role in how an author interprets and implements feedback comments. This suggests that affect can play a prominent role in helping to develop more effective feedback practices within writing groups. Helping writing communities develop a better understanding of affect within asynchronous written feedback comments can only help them to develop more useful feedback practices.

Writing an argumentation about a controversial issue from contradictory sources is a challenging task. It involves understanding, managing, and generating arguments and counterarguments from different sources to support a final position, conveyed in a formal structure. Despite its difficulty, argumentative writing is not often taught in higher education in Spain. Furthermore, online interventions regarding this type of task are scarce. For this reason, we designed and evaluated virtual training aimed at writing integrative and well-structured arguments in a distance learning university. Sixty-eight undergraduates participated in this pre-post with a control group design. The training included explicit instruction through video lectures and practice exercises with immediate feedback using open online resources (e.g., Moodle). The results show that after the instruction the participants' written products improved both in their structure, the number of arguments for the against-position, and the degree of integration of the two perspectives. However, those products that presented medium or maximum integration were still limited. These results illustrate how online instruction of argumentative writing can be implemented in higher education with positive results. However, students still need more support to expand their skills for generating integrative synthesis. Considering these results, we propose further improvements in the designed training.
