A self-learning system on the computer network is appropriate for supplementary learning since it is free from restrictions of time and space. Therefore, we have developed a self-learning system complementing regular lectures in order to help the student who wants to catch up with others by self-learning in science. For such a learning system it would be more effective to set up monitoring functions for the student's learning situations. Recently we devised such monitoring tools based on a database management system, "PostgreSQL", and implanted them in our learning system. The monitoring tools are classified into the following categories:
A: analysis of access-log to each teaching material,
B: individual records of learning progress and frequency of access etc.,
C: analysis of homepage examination and of questionnaire.
These tools are assembled into a homepage for managing purposes. So a teacher is able to know easily the latest information about the student's learning situations by watching the homepage which is visualized graphically as much as possible.
