Collaboration, communication, creativity, critical thinking and problem-solving are among the skills that are needed to study and work in this 21st century. As important as they are, evaluating, assessing and teaching them in a practical, scalable and efficient way is still a challenge not fully met by current pedagogical-technological practices. Multimodal Learning Analytics (MmLA), the processing and analysis of multiple sources of data to better understand and improve learning processes, has been posed as a possible solution to augment the natural capabilities of both instructors and students to provide and receive feedback to support the development of those skills. During this session, we will explore the affordances that low-cost sensors and current advances in artificial intelligence provide to automatically record and analyze face-to-face, complex learning processes as those involved for the development of 21st-Century Skills. Finally, we will discuss and ideate practical MmLA tools that could be built to augment your current teaching and learning practices.
