Typology
The “Domino Logic Gates” interactive learning environment is an Physics-Based Simulation which attempts to abstract the complexity of a system with the use of simple and ordinary objects.
This is a learning based simulation but should be integrated with additional resources previous to exploring it.
Description
Logic circuits are a central concept in understanding how computers and electronics work on the background. Despite computers perform really basic operations, it is really a challenge for humans to understand a system which computes millions of instructions per second. It is even more challenging to think that these operations are executed by electricity flowing around a maze of tiny little electronic components known as transistors. Against this background, it is extremely hard to explain the concept and abstraction behind logic gates without the aid of concrete systems. The “Domino Logic Gates” simulation is an interactive learning environment aimed at better understanding the complexity of how computers deal with logic gate operations and binary additions. In fact, each logic gate operation can be simulated using real domino blocks arranged in a specific pattern. Using the power of Unity built in physics, this simulation explores the behaviour of the AND, OR, and XOR logic gates and shows how a 2 bit binary addition can be represented with the combination of a small set of logic gates.
Terminal Learning Objectives
This interactive learning environment has the following TLO:
- Create an abstract mental model of computer logic gates
- Understand the 2 bit AND logic gate input and output
- Understand the 2 bit OR logic gate input and output
- Understand the 2 bit XOR logic gate input and output
- Understand the 2 bit binary addition by combining the AND and XOR logic gates
