Network-based programming language education environment based on a modular program diagram

We focus on program diagrams as one method for program modularizations. By using program diagrams, programmers can understand program structures, data structures and control flow faster, and divide a program into modules better. The paper proposes a network based programming language education environment that provides integrated support of programming languages, programming techniques, programming style, program documentation, modularization, and program abstraction using program diagrams as a foundation. The environment aims to transform the conventional CAI system into a multimedia one, unify the education environment with the actual programming environment, incorporate instructor guidance capabilities, and achieve integrated control and administration via a computer network
