Abstract
Background: The lab report is a commonly assigned genre in engineering lab courses; however, students often have difficulties meeting the expectations of writing in engineering labs. At the same time, it is challenging for engineering faculty to instruct lab report writing because they are often under-supported in writing pedagogies and usually unfamiliar with the extent of students' prior writing knowledge. Literature review: Literature on technical communication in engineering addresses the importance of a rhetorical approach to writing instruction, as well as an emphasis on genre. Extending this literature, research into writing transfer provides valuable insight for better understanding how undergraduates negotiate the engineering lab report as a new genre within this distinct rhetorical context. Research questions: 1. How effective is a transfer-focused writing pedagogy in supporting students' understanding of the genre conventions of engineering lab reports? 2. How does the transfer-focused writing pedagogy impact students' writing quality in five categories (rhetorical knowledge, organization, evidence, critical thinking, and disciplinary conventions)? 3. What are the rhetorical features that engineering students improve or struggle with the most with lab report writing? Research methodology: Four engineering instructors and two English instructors participated in this study to design and develop the lab report writing instructional module, and implemented the module materials into their engineering lab courses. The module, consisting of lab report writing instruction and assessment resources, shares a rhetorical approach and foundational writing terms with first-year composition courses to emphasize a writing-transfer pedagogy. We collected and analyzed undergraduates' lab report samples to evaluate the impact of the module on students' writing performance. Two sets of lab reports were collected for analysis: the sample sets before (control), during the 2015-2016 academic year; and after (experimental) implementation of the module, during the 2016-2017 academic year. Results and conclusions: Data collected via pre- and post-implementation writing artifacts show that a rhetorical approach to teaching lab reports helped students better understand the expectations of the lab report as a discipline-specific genre, and it developed students' understanding of the rhetorical features of engineering writing. The pilot module positively impacted the quality of students' lab reports, a finding that suggests that using a transfer-focused writing pedagogy can successfully support the transfer and adaptation of writing knowledge into gateway or entry-level engineering laboratory courses.
