Digital Technology focus
One of the key concepts within the Digital Technologies curriculum is Abstraction. Abstraction involves hiding details of an idea, problem or solution that are not relevant, to focus on a manageable number of aspects. Abstraction is a natural part of communication: people rarely communicate every detail, because many details are not relevant in a given context.
The idea of abstraction can be acquired from an early age. For example, when students are asked how to make toast for breakfast, they do not mention all of the steps explicitly if they assume that the listener is an intelligent implementer of the abstract instructions.
Central to managing the complexity of information systems is the ability to ‘temporarily ignore’ the internal details of the subcomponents of larger specifications, algorithms, systems or interactions. In digital systems, everything must be broken down into simple instructions.
A robot needs instructions or commands to know what to do. Ozobot robots have a visual sensor which it uses to gather information about its surroundings. It can follow visual commands which are made up of a series of colors.
Students can create or select visual commands to instruct the robot to complete a task.
