“…For instance, the vocabulary representation, lexical density, and speech rate of TED Talks are similar to those in lectures (Wingrove, 2017). They also resemble university lectures in the use of words and multimedia resources to express a speaker's stance and avoid misunderstanding (D'avanzo, 2015;Mattiello, 2019). With the common communicative purpose of knowledge dissemination in an online medium, we argue that a discourse analysis of TED Talks can inform the ways online learning can be designed.…”

Online learning has gained increasing attention during the COVID-19 pandemic. Teachers face social exigencies to design ways of knowledge dissemination in online instruction. We posit that understanding how knowledge can be represented in successful online academic genres can inform teachers on how they can design students’ online learning experiences. This study examined how scientific knowledge is disseminated in one of the most widespread academic genres, TED Talks, which share discoursal similarities with other academic genres such as online lectures. This study adopted a systemic functional multimodal discourse analysis approach to explore how a presenter used speech, images, and gestures to disseminate knowledge. The analysis shows that a presenter orchestrates speech, images, and gestures strategically to clarify the scientific ideas and engage the audience. Based on understanding how the three semiotic modes are used to disseminate scientific knowledge in accessible and engaging ways, this paper discusses how insights on multimodal orchestration can function as a heuristic tool to inform design in online learning.

“…the scholarly interest in the generic features of ted talks tends to focus on its rhetorical structure (chang and Huang, 2015; Jiang, 2017) and microlinguistic features which help to achieve accessibility, engagement, and authority (compagnone, 2015;Mattiello, 2017Mattiello, , 2019scotto di carlo, 2014a, 2014b. For instance, based on Hyland's (2010) work on the author-reader relationship in popular science articles, scotto di carlo (2014b) studied the use of engagement techniques (evaluative and emotive adjectives, inclusive pronouns) in ted talks, and found those strategies were able to balance the expert and laypeople asymmetry and achieve audience involvement.…”

In today’s neoliberal economy, digital platforms have led to a proliferation in science popularization where scientists package their messages for the wider public. Our study explores how science ideas are disseminated in one of the most widespread digitally mediated genres of science popularisation, the TED talks. We adopt a multimodal discourse analysis approach to explore how the presenter orchestrates her speech, visuals on slides, and hand gestures to achieve the communicative purposes of the TED talk. From the analysis, it is observed that the presenter uses many specific linguistic choices to clarify the ideas and build the speaker’s authority. These language choices are supported by visual choices and gestures. We unpack the presenter’s multimodal semiotic choices and examine how they work together to communicate scientific ideas to the layman and engage with the audience. Our study reveals a deeper understanding on the power of language, visuals, and gestures as communicative tools in presentations, and sheds light on how the three modes are orchestrated to present scientific ideas in an accessible and engaging manner as part of science popularization.

“…In non-literary contexts, Riihimäki (2019) conducts a corpus-assisted discourse study of Hansard which investigates how the UK’s identity is constructed in parliamentary debates about the EU. Mattiello (2019) undertakes a corpus-based analysis of TED talks, specifically focussed on how the lexicon is used to describe cancer-related topics to non-experts. Work in corpus studies in 2019 has also had much to say about issues connected to gender and identity.…”
