To improve text quality in higher education, training writing strategies (i.e., text structure application, summarization, or language use) and provision of feedback for revising (i.e., informative tutoring feedback or try-again feedback) were tested in combination. The aim was to establish whether first, strategy training affects academic writing skills that promote coherence, second, whether undergraduates and postgraduates benefit differently from feedback for revising, and third, whether training text structure application strategy in combination with informative tutoring feedback was most effective for undergraduates' text quality. Undergraduate and postgraduate students (N = 212) participated in the 2-h experimental intervention study in a computer-based learning environment. Participants were divided into three groups and supported by a writing strategy training intervention (i.e., text structure knowledge application, summarization, or language use), which was modeled by a peer student in a learning journal. Afterward participants wrote an abstract of an empirical article. Half of each group received in a computer-based learning environment twice either try-again feedback or informative tutoring feedback while revising their drafts. Writing skills and text quality were assessed by items and ratings. Analyses of covariance revealed that, first, text structure knowledge application strategy affected academic writing skills positively; second, feedback related to writing experience resulted in higher text quality: undergraduates benefited from informative tutoring feedback, postgraduates from try-again feedback; and third, the combination of writing strategy and feedback was not significantly related to improved text quality.Keywords: coherence, feedback, higher education, text quality, writing strategies inTrODUcTiOn The writing performance of freshmen and even graduate students reveals a gap between writing skills learned at school and writing skills required at the college or university level (Kellogg and Whiteford, 2009): writers at school are able to transform their knowledge into a text that they can understand and use for their own benefit. Academic writing requires in addition to that presuming the readers' understanding of the text written so far to establish a highly coherent text (Kellogg, 2008).Several studies have shown that to improve writing, it is beneficial to train writing strategies and to support the writing process through feedback (Graham, 2006;Nelson and Schunn, 2009;Donker et al., 2014). This is also true for higher education (Nicol and Macfarlane-Dick, 2006;MacArthur , 2015;Wischgoll, 2016). Writing strategies can help learners to control and modify their efforts to master the writing task (Bereiter and Scardamalia, 1987). Feedback for improving writing provides information about the adequacy of the writing product (Graham and Perin, 2007). On the other hand, feedback that interrupts the writing process might be inhibitive (Corno and Snow, 1986). Feedback that is administered adapti...
