Even the most experienced programmers use simple visual models and techniques to plan an effective algorithmic solution. In this video, students are introduced to the IPO model and flowcharts as two such methods to abstract unnecessary information in a problem, decompose it into smaller tasks, a recognise patterns and repetition, and program a series of simple steps for a computer to follow.

Using the analogy problem of washing dirty dishes, this video explores the IPO model and pseudocode as tools to guide computational thinking. Students of lower secondary digital technologies will understand how using pseudocode can be an accessible preliminary step in the design process before attempting to write a program in their chosen syntax.

Introducing the concepts of abstraction, decomposition, algorithm design and pattern recognition, this video gets inside the ‘mind’ of a computer to understand why computational thinking this is a crucial first step to designing a successful program. Students and teachers of lower secondary digital technologies will find this an approachable foundation to computational thinking. Show Less
