l'ère numérique-Analyse de l'orchestration multimodale de TED Talks  \nJingxin Jiang, Chongqing Open University, China; National Institute of Education, Nanyang Technological University, Singapore  \nFei Victor Lim, National Institute of Education, Nanyang Technological University, Singapore  \nAbstract  \nOnline 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.  \nKeywords: Online learning ; TED Talks ; Multimodal discourse analysis ; Speech ; Image; Gesture  \nCJLT/RCAT Vol. 48 (4)  \nRésumé  \nL'apprentissage en ligne a fait l'objet d'une attention croissante pendant la pandémie de COVID-19. Les enseignants sont confrontés à des exigences sociales pour concevoir des moyens de diffusion des connaissances dans l'enseignement en ligne. Nous postulons que la compréhension de la façon dont les connaissances peuvent être représentées dans des genres académiques en ligne réussis peut informer les enseignants sur la façon dont ils peuvent concevoir les expériences d'apprentissage en ligne des étudiants. Notre étude a examiné la manière dont les connaissances scientifiques sont diffusées dans l'un des genres académiques les plus répandus, les TED Talks, qui partagent des similitudes discursives avec d'autres genres académiques tels que les cours magistraux en ligne. Cette étude a adopté une approche systémique d'analyse fonctionnelle du discours multimodal pour explorer la manière dont un présentateur utilise la parole, les images et les gestes pour diffuser des connaissances. L'analyse montre qu'un présentateur orchestre la parole, les images et les gestes de manière stratégique afin de clarifier les idées scientifiques et d'impliquer le groupe. Sur la base de la compréhension de la façon dont les trois modes sémiotiques sont utilisés pour diffuser des connaissances scientifiques de manière accessible et engageante, cet article discute de la façon dont les idées sur l'orchestration multimodale peuvent fonctionner comme un outil heuristique pour informer la conception de l'apprentissage en ligne.  \nMots-clés : apprentissage en ligne ; TED Talks ; analyse multimodale du discours ; discours ; image ; geste  \nIntroduction  \nAdvancement in digital technology and the prevalence of new media have led to a fundamental change in the education sector, with online learning and teaching now considered at the forefront of 21st century pedagogy (Ali, 2020; Miller et al., 2020). The outbreak ofCOVID-19 has propelled a massive transition from face-to-face classrooms to online learning systems around the world and has made online learning a new normal (Martin, 2021; Teo et al., 2021) . However, the effectiveness of online learning in the pandemic is debatable (Adedoyin & Soykan, 2020; Hamid et al., ","cbCaikGbuDOEG5AG","https://ap.wps.com/l/cbCaikGbuDOEG5AG","pdf",377627,25,"English","# Introduction\n# Designing Knowledge Dissemination in a Digital Era - Analyzing TED Talks’ Multimodal Orchestration","[{\"question\":\"What problem does the study address about online learning during COVID-19?\",\"answer\":\"It addresses the need for teachers to design ways to disseminate knowledge effectively in online instruction, amid debates about online learning effectiveness.\"},{\"question\":\"Which academic genre is analyzed to study scientific knowledge dissemination?\",\"answer\":\"The study examines TED Talks as an academic genre that shares discoursal similarities with other online academic genres such as online lectures.\"},{\"question\":\"How are TED Talks analyzed in terms of multimodal communication?\",\"answer\":\"The study uses systemic functional multimodal discourse analysis to explore how a presenter uses speech, images, and gestures to disseminate knowledge.\"}]","Designing Knowledge Dissemination in a Digital Era - Analyzing TED Talks’ Multimodal Orchestration | PDF",1792086755,63]
