This proposed research investigates the use of ThUMP by classroom educators to foster high order thinking through authentic and meaningful practice activities. Research suggests that practice is require to obtain expertise in complex subject areas such as STEM (Science, Technology, Engineering and Mathematics). ThUMP allows educators to author practice activities that students can access using mobile devices. This proposed research adopts a design based approach in order to provide feedback / feed forward to the Mathtoon’s developers. Findings from this study will be shared in recognized international conferences and publications.
