Development of a Web system for making Problem Analysis Diagram (PAD)

摘要

This PAD(Problem Analysis Diagram) making system is targeted at students and teachers who perform computer programming in a university etc. The system on the Web for use from the outside through the Internet aiming at “offer of the simple algorithm building method”, “learning support of structured programming”, and “learning support of programming language” was developed. This system has many useful capabilities and also has easiness of operations. In this paper, first, we outline a structured program and PAD. Next, we describe the internal configuration of this system, describe the login into this system, and describe capabilities and their usage. Finally, we describe the present evaluation of this system and some future plans.
