The present article describes how scaffolding is implemented in an intelligent tutorial system call NTUs (number transcoding tutorial system), and what are the results of the system tested empirically on a group of grade students in fostering their number concepts. To use NTUs the system first analyzes a user's errors on a number transcoding task, and the results of analysis are used to infer the user's zone of proximal development (ZPD). A scaffolding process which vas designed with inspiration from how people learn Chinese calligraphy is provided next in the user's ZPD. An empirical test indicates that NTUs can not only foster students' number concepts, but can also attract them to use it.
