How Interactivity Works: priming of mental rotation
World Conference on Educational Multimedia, Hypermedia and Telecommunications (EDMEDIA) 2004:1 , 2004

Glenn Smith, Stony Brook University, USA; Sinan Olkun, Abant Izzet Baysal University, Turkey

This study has important implications for design of microworlds such as Hypergami, and Logo which use interactivity to help students learn spatial mental models involving math and science. This study tested the hypothesis that interactively rotating ...
