Ratih Ayu Apsari is a PhD student in the Learning Sciences and Human Development at the University of California, Berkeley. Her research centers on promoting epistemic diversity and cultural funds of knowledge among students by incorporating culturally situated embodied cognition into mathematics education. She is currently engaged in the Geometry Resources in Dance (GRiD) project, a design-based research intervention rooted in the tradition of Balinese dance. GRiD design consisted of a set of dancing geometry tasks and a learning environment as a gridded floor mat to objectify tacit attentional anchors for movement coordination into auxiliary lines for geometric practice. Students attend to and foreground particular lines on the mat in order to coordinate their dance movements. These tacit attentional anchors then become explicit auxiliary lines for geometric practice. For further information regarding her work, please visit bit.ly/GRiD
