Multimodal Learning Analytics (MMLA) systems integrate diverse data to provide real-time insights into student learning, yet their design faces the challenge of limited established guidelines. This study investigates essential design considerations for MMLA systems during the research and development phase, aiming to enhance their effectiveness in educational settings. A qualitative approach employing semi-structured interviews was conducted with a diverse group of researchers in the MMLA field. Deductive and thematic analysis were used to identify key design considerations, including technology integration, constraints and learning scenarios. The analysis further revealed intersections between various design considerations, both confirming existing themes and highlighting new emergent ones. Based on the findings, the MMLA Design Framework (MDF) was developed to provide a structured approach to guide the design and development of MMLA systems. This framework, along with the identified design considerations, addresses the lack of conventional practices in MMLA design and offers practical insights for practitioners and researchers. The results of this study have the potential to significantly impact both research and educational applications of MMLA systems, paving the way for more effective and informed designs.

Designing MMLA systems is a complex task requiring a wide range of considerations. In this paper, we identify key considerations that are essential for designing MMLA systems. These considerations include data management, human factors, sensors and modalities, learning scenarios, privacy and ethics, interpretation and feedback, and data collection. The implications of these considerations are twofold: 1) The need for flexibility in MMLA systems to adapt to different learning contexts and scales, and 2) The need for a researcher-centered approach to designing MMLA systems. Unfortunately, the sheer number of considerations can lead to a state of "analysis paralysis," where deciding where to begin and how to proceed becomes overwhelming. This synthesis paper asks researchers to rethink the design of MMLA systems and aims to provide guidance for developers and practitioners in the field of MMLA.
