Stronger literature review skills linked to better academic writing

Writing an effective literature review is a core component of academic research. Beyond  summarizing prior studies, it helps identify research gaps, justify new inquiries, and position research within a broader scholarly context. Despite its importance, however, literature review writing is often treated as an implicit skill, particularly in non-English academic settings.  

A study by Xinhua Zhu, Yuan Yao, Jun Lei, and Qi Lu, published on February 12, 2026, in ECNU Review of Education, finds that literature review skills are a key driver of academic writing quality among Chinese postgraduate students. The results highlight how engaging with existing research shapes more effective academic writing.

The study involved 286 postgraduate students enrolled in an academic writing course at a research-intensive university in China. Participants completed two assessed tasks: a literature review and a research proposal, which were evaluated using detailed analytic rubrics. The researchers assessed performance across multiple dimensions, including source use, synthesis, referencing, identification of research gaps, language use, organization, and contextual awareness.

Using exploratory factor analysis (EFA), the researchers identified four interrelated dimensions of literature review writing. These include Citation and Synthesis, Research Question Elicitation, Language Expression and Organization, and Contextual Awareness. Together, these dimensions capture both technical and higher-order aspects of academic writing.

Further latent profile analysis (LPA) revealed clear differences in student performance. Two distinct groups emerged: those with relatively weaker literature review writing skills and those with moderate to strong skills. Students in the latter group consistently outperformed their peers across all dimensions.

The study also finds a strong link between literature review writing skills and broader academic writing performance. Students with stronger literature review writing skills achieved significantly higher scores on the research proposal task, which assessed topic knowledge, research design, and overall writing quality. This suggests that literature review writing is not a standalone exercise, but a core component of successful academic writing. 

At the same time, the research highlights a shared challenge. The ability to identify research gaps and formulate research questions, referred to as research question elicitation, was the weakest area across both groups. This points to an important gap in postgraduate academic writing instruction.

The findings underscore the need for more targeted support in academic writing education. Rather than focusing primarily on grammar or vocabulary, instruction should place greater emphasis on higher-order skills such as synthesis, argument development, and critical evaluation. Providing clear models, structured guidance, and iterative feedback may help students strengthen these skills.

Overall, the study positions literature review writing as a central, teachable component of academic literacy. By offering a validated skill framework and empirical evidence of its impact, the study provides a foundation for more effective and systematic approaches to postgraduate writing instruction.
