Introduction

VOOPA (Visualising Object-Oriented Progamming using Analogies) is a game-like application designed to help learners visualise fundamental OOP concepts.

The set of activities are designed to target known difficulties and misconceptions identified in computing education literature.

Controls

Here’s an instructional video about it. The demo in the video shows the C++ version, but it works exactly the same for the Java version:

The following instructions will also help you understand how to move around in the game:

The Analogy

The analogy used in the visual activities revolves around houses. The mappings of the OOP concept to the house analogy are summarised as follows:
