“…These include differences between summary and response essays based on the same source text (Ascenci on Delaney, 2008), summary and argumentative essays on the same topic (Gil, Braten, Vidal-Abarca, & Strømsø, 2010;Greene, 1993), summary and opinion essays (Shi, 2004), writing in a restricted manner (short answers to study questions) or an extended manner (in analytic essays) (Newell & Winograd, 1995), open-ended versus instructor-directed writing tasks (Petric & Harwood, 2013), argumentative writing based on one or two source texts (Mateos, Martin, Villaon, & Luna, 2008;Plakans, 2010), and science inquiry writing tasks from sources of variable reliability (Wiley & Voss, 1999). As observed above in respect to students' abilities in Claim 2, numerous studies have found differences in expectations and practices for writing from sources across academic disciplines and broadly between students' writing in the arts and in sciences (Mateos et al, 2007;Rinnert & Kobayashi, 2005;Shi, 2012aShi, , 2012bThompson et al, 2013). The genre of writing a thesis has been studied extensively and shown to involve unique, extensive, sophisticated, and varied demonstrations of scholarly citation conventions (Basturkmen, 2009;Harwood, 2010;Harwood & Petric, 2012;Petric, 2007Petric & Harwood, 2013).…”
