Analysis of a Programming Process Sharing the Card-Type Programming Tool "Pro-Tan".

We have been developing a tangible programming tool called “Pro-tan” which has a card-type interface. This paper reports the system configuration of Pro-tan and analysis of the usefulness when two users share Pro-tan. We conducted an experiment comparing Pro-tan with the programming software “Studuino”, which has an interface suitable for operation by children. We evaluated the usefulness of Pro-tan in a collaborative learning process in which two users share the same system.
