Shell Noun Usage in Science Undergraduate Academic Writing: Insights from Mukuba University, Zambia

This study examined the use of shell nouns in the academic writing of science undergraduate students at Mukuba University, Zambia, focusing on their frequency, patterns, and functions across multiple disciplines. The topic was chosen due to the critical role of shell nouns in enhancing coherence, formality, and objectivity in academic writing, which are essential skills for scientific communication. Grounded in Halliday and Hasan’s theory of cohesion, the research aimed to (1) investigate the frequency of shell noun use across disciplines, (2) identify patterns in their usage across academic years, and (3) evaluate their functional contributions to coherence, formalization, and objectivity in student writing. A qualitative approach was employed, involving the analysis of written samples from disciplines including Biology, Chemistry, Public Health, Nutrition Science, Agricultural Science, Computer Science, Environmental and Climate Change, and Biomedical Science. The data set consisted of lab reports, research papers, and essays collected from first-year to final-year students. The data analysis involved frequency counts and thematic coding to identify trends and patterns in shell noun usage. The findings revealed notable disciplinary variations, with Chemistry and Biomedical Science demonstrating higher frequencies of shell noun use. Shell nouns played a vital role in maintaining textual coherence, formalizing tone, and enhancing objectivity in the students' writing. More advanced usage was evident among final-year students, suggesting a developmental progression in academic writing skills. However, challenges such as inconsistent use and difficulty applying shell nouns effectively in complex writing tasks were also identified. The study highlighted the importance of targeted pedagogical interventions, recommending the inclusion of explicit instruction on shell noun usage in writing curricula. Suggestions for future research included expanding the sample size, incorporating a broader range of genres, and adopting a longitudinal approach. By examining linguistic features in academic writing within a sub-Saharan African context, this research provided valuable insights for educators seeking to enhance writing instruction and support student success.
