For context on why I’m interested in this, see the previous post.
I’ve done some searches into the question of oral and written peer feedback, and been surprised at the paucity of results. Or rather, the paucity of results outside the field of language teaching, or teaching courses in a language that is an “additional language” for students. I have yet to look into literature on online vs. face-to-face peer review as well. Outside of those areas, I’ve found only a few articles.
1. Van den Berg, I., Admiraal, W., & Pilot, A. (2006) Designing student peer assessment in higher education: analysis of written and oral peer feedback, Teaching in Higher Education, 11:2, 135-147. http://dx.doi.org/10.1080/13562510500527685
In this article Van den Berg et al report on a study in which they looked at peer feedback in seven different courses in the discipline of history (131 students). These courses had peer feedback designs that differed according to things such as: what kind of assignment was the subject of peer feedback, whether the peer feedback took place alongside teacher feedback or whether there was peer feedback only, whether students who commented on others got comments from those same others on their own work or not, how many students participated in feedback groups, and more. Most of the courses had both written and oral peer feedback, though one of the seven had just written peer feedback.
The authors coded both the written and oral feedback along two sets of criteria: feedback functions and feedback aspects. I quote from their paper to explain these two things, as they are fairly complicated:
Based on Flower et al . (1986) and Roossink (1990), we coded the feedback in relation to its product-oriented functions (referring directly to the product to be assessed): analysis, evaluation, explanation and revision. ‘Analysis’ includes comments aimed at understanding the text. ‘Evaluation’ refers to all explicit and implicit quality statements. Arguments supporting the evaluation refer to ‘Explanation’, and suggested measures for improvement to ‘Revision’. Next, we distinguished two process-oriented functions, ‘Orientation’ and ‘Method’. ‘Orientation’ includes communication which aims at structuring the discussion of the oral feedback. ‘Method’ means that students discuss the writing process. (141-142)
By the term ‘aspect’ we refer to the subject of feedback, distinguishing between content, structure, and style of the students’ writing (see Steehouder et al., 1992). ‘Content’ includes the relevance of information, the clarity of the problem, the argumentation, and the explanation of concepts. With ‘Structure’ we mean the inner consistency of a text, for example the relation between the main problem and the specified research questions, or between the argumentation and the conclusion. ‘Style’ refers to the ‘outer’ form of the text, which includes use of language, grammar, spelling and layout. (142)
They found that students tended to focus on different things in their oral and written feedback. Written feedback over all the courses tended to be more product-oriented than process-oriented, with a focus on evaluation of quality rather than explaining that evaluation or offering suggestions for revision. In terms of feedback aspect, written feedback focused more on content and style than structure (143).
