Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will discover the computational thinking techniques; decomposition, abstraction and algorithmic thinking. They will reflect on differences between algorithms and computer programs and explore how algorithms can be represented. Pupils will explore the impact of algorithmic bias.
Lesson Summary
You will learn to describe the differences between algorithms and computer programs.
Key Notes
- An algorithm is a series of defined logical steps that can be followed to solve a problem.
- A computer program is a way of implementing an algorithm, by writing it in a language that a computer can understand.
- A single algorithm can be implemented in many different computer programs.
Vocabulary To Learn
- algorithm: a set of step-by-step instructions to solve a problem
- computer program: a way of implementing an algorithm by writing it in a language that a computer can use
- logic: a system of rules that determine the flow of instructions
Common Mistakes To Avoid
- Algorithms and computer programs are actually the same thing.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
An algorithm is a series of defined logical steps that can be followed to solve a problem. A computer program is a way of implementing an algorithm, by writing it in a language that a computer can understand.
2. Define this computing term and give one practical example. 'algorithm'
a set of step-by-step instructions to solve a problem. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Algorithms and computer programs are actually the same thing. Correction: A computer program is a specific implementation of an algorithm's logic. A clearly written algorithm provides instructions that can be implemented in various ways including, but not limited to, computer programs.
