Abstract
Background: Swales's Create a Research Space (CaRS) is a popular model for writing research article (RA) introductions. CaRS prescribes three broad moves-establishing a territory, establishing a niche, and presenting the present work. This study assesses the applicability of a problem-solution patterns (PSP) approach to facilitate Move 1 in CaRS by analyzing RAs in materials science and engineering. Research questions: 1. Is structuring an RA introduction using problem-solution patterns a common approach in published RAs in materials science and engineering? 2. How does PSP facilitate the setting of boundaries between territory and niche in these RAs? Literature review: Variants of CaRS have been widely applied to study RA introductions. Even though the 2004 version of CaRS has been deemed effective in describing the structure of RA introductions in a number of disciplines, its prescription of Move 1 may not be easily operationalized in teaching engineering research writing. For problem- or application-based RAs, the territory can be established with PSP while preserving other CaRS moves. Methodology: This exploratory study employs a text analysis approach to assess 30 RA introductions from three materials science and engineering journals. Results and discussion: PSP is found in most RA introductions. By integrating PSP into CaRS, the proposed model can capture problem-solution cyclicity as a build-up move for territory and niche establishment. Conclusion: Because problem-solving is central to engineering research, RA introductions can be structured using naturally-occurring problem-solution patterns. PSP-CaRS may serve as an effective writing model for RA introductions in engineering-related fields.
