“…At present, research in MMLA has focused on studying and modelling learning strategies (Mangaroska, Sharma, Giannakos, Traeteberg, & Dillenbourg, 2018;Worsley & Blikstein, 2015), predicting high-level constructs such as learners' attention and engagement (Chan, Ochoa, & Clarke, 2020), building more accurate learner models (Giannakos, Sharma, Pappas, Kostakos, & Velloso, 2019), designing multimodal learning interfaces (Echeverria et al, 2019), or generating new insights into teaching and learning at a more fine-grained level (Martinez-Maldonado et al, 2020;Prieto, Sharma, Kidzinski, Rodríguez-Triana, & Dillenbourg, 2018). In fact, MMLA promises to bridge theory and complex learning behaviour (Worsley, 2014), support educators' role in addressing students' individual needs, expectations, and skills in physical (Ogan, 2019) and digital (Ochoa et al, 2018) learning settings, as well as tackle the complexities of orchestrating (e.g., designing, managing, adapting) learning activities at multiple social levels beyond the challenges (e.g., time, mental effort) instructors face in their everyday practice (Prieto et al, 2018).…”
