Participants, 26 males and 23 females, are 6th grade level students. The research was conducted in vivo naturalistic case procedure, a type of formative research. Students’ interviews, observation and thinking aloud during application are as data source. Data were collected from students in three application periods. Iterative process was followed for study and the outputs of applications were the input of next prototype. After the third application, the participants’ satisfaction was ensured and developments were ended. In conclusion, the important issues to be considered in the design of instructional material developed for multitouch screens are listed under the three groups: instructional designers and developers, teachers while using in classroom and researchers taking their agenda. Defined criteria are expected to guide for these people for their study.
