TL;DR

This paper presents the VJ-Lab, a web-based virtual simulation lab built with Java to enhance computer science education at the National University of La Plata. It enables students to interactively explore data network protocols and data structure algorithms through intuitive, pictorial applets developed in a software development course, fostering active learning through hands-on simulation experiences.

ABSTRACT

The VJ-Lab is a project oriented to improve the students learning process of Computer Science degree at the National University of La Plata. The VJ-Lab is a Web application with Java based simulations. Java can be used to provide simulation environments with simple pictorial interfaces that can help students to understand the subject. There are many fields in which it is difficult to give students a feel for the subject that they are learning. Computer based simulations offer a fun and effective way to enable students to learn by doing. Both, practicing skills and applying knowledge are both allowed in simulated worlds. We will focus on the VJ-Lab project overview, the work in progress and some Java based simulations running. They imitate the behavior of data network protocol and data structure algorithms. These applets are produced by the students of the 'Software Development Laboratory' course.

Motivation & Objective

• To improve the learning process of computer science students at the National University of La Plata through interactive, simulation-based education.
• To address the challenge of helping students develop an intuitive understanding of complex computer science concepts such as data network protocols and algorithm behavior.
• To provide a practical, student-developed platform where learners can practice skills and apply knowledge in simulated environments.
• To integrate simulation tools into the curriculum of the 'Software Development Laboratory' course as part of a project-oriented learning approach.
• To create accessible, web-based Java applets that visually represent abstract computational processes for better comprehension.

Proposed method

• The VJ-Lab is implemented as a web application using Java applets to deliver interactive simulations.
• Simulations are designed with simple pictorial interfaces to visualize dynamic behaviors of data structures and network protocols.
• Students in the 'Software Development Laboratory' course are responsible for developing the simulation applets as part of their coursework.
• The simulations model real-time behaviors of data structure algorithms and network protocol operations to reflect actual system dynamics.
• The platform is built to be accessible via standard web browsers, enabling remote and repeated access for learners.
• The system emphasizes user interaction, allowing students to manipulate inputs and observe outcomes in real time.
