Computer-enhanced Multimodal Modeling for Supporting a Learner Generated Topic

This study describes the emergence of a multimodality modeling workshop involving a 3D computer model, aiming to facilitate the workshop participants’ learning of their self-generated astronomy topic – lunar libration. This qualitative study took place in designing learning environments in informal learning contexts that leveraged five university students’ interests and prior knowledge in astronomy, observation experiences and emerging questions. The findings show that the modified visual representation in a computer model improved the quality of their observation experiences and assisted them to consolidate their understanding of lunar libration. Further, computer-enhanced multimodality mediated by modeling software (i.e. Astronomicon) promoted not only learners’ selfdirected exploration but also collaborative discussion toward understanding of the lunar libration. We consider implications for promoting learner-generated topics supported by computer-enhanced multimodal modeling.
