Abstract: An interactive scholastic teaching device may use first and second portions of a touchscreen for presenting problems and receiving answers to the problems from a user. The first portion of a touchscreen display is used for presenting one or more scholastic problems for a user during a problem session, and the second portion of the touchscreen display is used for recording one or more traces manually input by the user on the second portion of the touchscreen display during the problem session. A memory stores the one or more traces. The touchscreen display may also include a third portion having one or more touch buttons structured to accept input from the user during the problem session, which may also be stored in the memory, and associated with the stored traces. The traces may be stored in image form, moving image form, or in data that may be re-created to form a moving image.
