Using Video Timeline as an Analytical Tool
In this study, I suggested an innovative methodology to Trace the Paths of Interactions (TPI) on video data, which is designed to investigate and analyse the development of learning in video data. In particular, I have adapted Arzarello’s (2014) modes of touchscreen-based interactions and Nemirovsky et al.’s perceptuomotor integration approach (2013), augmented by a focus on the role of the bodily interactions —especially the fingers and hands— to explain mathematical learning with a touchscreen device. In this methodology, video timeline is used as an analytical tool and StudioCode software is utilized to track the designated modes of interactions over the given stretch of time.
Overall, the study demonstrates that the multimodal touch and sight feedback via a touchscreen device can serve to assist in the learning of mathematical concepts. The results are submitted for publication [1,2]
