Peer review is useful for providing students with formative feedback, yet it is used less frequently in STEM classrooms and for supporting writing-to-learn (WTL). While research indicates the benefits of incorporating peer review into classrooms, less research is focused on students’ perceptions thereof. Such research is important as it speaks to the mechanisms whereby peer review can support learning. This study examines students’ self-reported approaches to and perceptions of peer review and revision associated with WTL assignments implemented in an organic chemistry course. Students responded to a survey covering how they approached peer review and revision and the benefits they perceived from participating in each. Findings indicate that the assignment materials guided students’ approaches during both peer review and revision. Furthermore, students described various ways both receiving feedback from their peers and reading their peers’ drafts were beneficial, but primarily connected their revisions to receiving feedback.

This tenth-anniversary volume is an occasion to read A Journal of Critical Thinking and Writing reflexively, by turning its focus on critical thinking and writing back on itself as an academic genre that organizes knowledge according to time.A journal assumes time to be a linear, unidirectional movement segmented into a past, which has already happened; a present, which is happening; and a future, which has yet to happen.This sequence is inscribed in a journal's paratextuality, such as a chronological division into annual volumes, which conforms reading to knowledge configured temporally: a reference to a text locates that text in the past; an argument against locates a text in the present; and questions for further research locate a text in the future.This commonplace notion of time informs a process of inquiry understandable across the disciplines, but it is also at odds with disciplinary theories of temporality.Consider, for a moment, how the visual arts can realign perception with uncommon patterns of time.When this volume's cover image is viewed according to its title, Counter-Curve (see Figure 1), it creates a curvilinear motion that either quickens along contracting concentric circles or slows along expanding concentric circles.Each motion, as a counter-curve, implies the other, inverse motion, but the either/or structure of perception limits our awareness of time's bidirectionality, described by the image's artist, Dana Karwas (n.d.), as "a single moment curving infinitely around on itself" (para.10).As a moment, time is undivided into past, present, and future.It is instead composed of recurrences that simultaneously spiral inwardly toward an infinitesimal center of nonrecurrence, a point of origin, and outwardly toward an infinite circumference that is the end of time.Because our perception can align with time's contraction or expansion, but not both at once, Counter-Curve can perhaps explain an otherwise paradoxical experience of the moment as ephemeral and durable.If the last ten years of Double Helix is telescoped to this swirl of time, then the practice of reading the journal changes.It locates one in the moment, a condition of "mindfulness" that Ellen Carillo (2016) has advocated for reading, in which one sustains attention to the text, undistracted by the past or the future, because, in this case, neither the past nor the future exists.A sequence of texts is thereby converted into an intertext, and a reference to, an argument against, and questions for further research become recurring features of intertextuality that advance an area of knowledge toward pure originality and the completion of knowledge as ideal and inverse limits of inquiry (see Figure 2).

While many STEM faculty believe Writing-to-Learn to be an effective instructional tool, instructional barriers such as the time and effort required to provide substantive feedback to their students limit the use of writing in STEM classrooms. Incorporating peer review and revision into the writing process can help mitigate these barriers while additionally supporting the learning process. This study presents an analysis of a Writing-to-Learn assignment that incorporates peer review and revision into a large introductory statistics course, where this study specifically focused on whether engaging with these processes results in changes in how students write about the content targeted by the assignment. Our results demonstrate that students made content-focused revisions between drafts that increased the amount of content they explained correctly. Additionally, our study provides evidence that students benefit from reading peers’ work in a content-focused peer review and revision process. Overall, this study shows that incorporating peer review and revision into writing assignments focused on developing content knowledge provides students with substantive feedback and enhances students’ conceptual learning.
