Adhering to Hyland’s (2019) Interpersonal Model of Metadiscourse, this paper examines the distribution of interactive metadiscourse markers across various topics in popular science commentaries. The corpus comprises 300 popular science commentaries, including 150 magazine articles and 150 newspaper articles, spanning nine years from 2015 to 2024. This period saw increased public debates due to significant scientific discoveries, making the analysis of such engaging content particularly relevant. A corpus of 346,825 running words was analyzed using Antconc software, identifying 24,492 instances of interactive markers. The study shows that subcategories of interactive metadiscourse are frequently used in both popular science magazine and newspaper articles. However, interactive markers appear more frequently in magazine articles than in newspaper articles, indicating that the former has more structured content. Chi-square test results for subcategories of interactive metadiscourse reveal significant differences in the distribution of transition markers, endophoric markers, evidentials, and code glosses between the two corpora. This suggests that ESP and EAP material developers should create more explicit learning resources. Such resources could help language instructors and novice researchers, especially those whose first language is not English, understand how the rhetorical functions of interactive markers influence writing styles across different genres and facilitate successful reader interaction.

The increasing availability of scientific knowledge through digital platforms has transformed how scientific discourse reaches the general public. This study examined the use of interactional metadiscourse markers across four leading popular science subgenres: books, TV documentaries, magazine articles, and newspaper articles. The aim was to investigate the language features of these markers, focusing on how they engage readers and highlight writer presence in different subgenres. A corpus of 987,625 words was analyzed using AntConc software (Anthony, 2019) and 80,260 instances of interactional markers were identified according to Hyland’s (2019) Interpersonal Model of Metadiscourse. The study revealed how hedges, boosters, attitude markers, self-mentions, and engagement markers function to create persuasive and accessible content. Interestingly, interactional markers appeared most frequently in TV documentaries, suggesting a heightened effort to engage audiences through this medium. Chi-square tests revealed significant differences in marker usage across subgenres; however, the small effect sizes (Cramér’s V) indicated that these differences are of only modest practical significance. These results provided insight into how popular science writers adapt their rhetorical strategies to suit different communicative contexts and audience expectations. The findings also have pedagogical implications. Incorporating features of popular science into ESP/EAP materials, such as authentic texts and structured practice with interactional metadiscourse markers, can make scientific content more engaging and accessible for learners. Raising learners’ awareness of interactional metadiscourse markers can improve writing skills, especially for novice writers in non-English academic settings, helping them better engage readers and communicate more effectively.
