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 use physical computing to explore the concept of selection. Pupils will use conditions to control the flow of a program. They will make use of their knowledge of repetition when introduced to the concept of selection and write programs that utilise this concept.
Lesson Summary
You will learn to create a physical project that includes selection.
Key Notes
- An algorithm can describe what a physical model will do.
- Selection can be used to produce an intended outcome.
- Programs are improved through debugging.
Vocabulary To Learn
- algorithm: a precise set of ordered steps which can be followed by a human or a computer to do a task
- repetition: part of a program where one or more commands are run multiple times in a loop
- debug: finding and fixing errors in a program
Common Mistakes To Avoid
- You should write all the code before testing.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
An algorithm can describe what a physical model will do. Selection can be used to produce an intended outcome.
2. Define this computing term and give one practical example. 'algorithm'
a precise set of ordered steps which can be followed by a human or a computer to do a task. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: You should write all the code before testing. Correction: Test small parts frequently to catch errors early. It is easier to fix a few errors at a time than all of them at once.
