This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit brings together all the four programming constructs: sequence, repetition, selection and variables whilst also utilising a physical device - the micro:bit. Pupils begin with a simple program to build and test and then take on three new projects, with each adding more depth and complexity.
Lesson Summary
You will learn to update a variable based on the state of an input.
Key Notes
- A variable's value can be changed according to a condition.
- Physical inputs can be tested as part of conditions in if...then...else statements.
- Checking the value of a variable doesn't change the variable's value.
Vocabulary To Learn
- input: data that is sent to a program to be processed
- sensor: an input device that allows a computer to collect data from the physical environment
- variable: a named piece of data stored in a computer's memory which can be accessed and changed by a computer program
Common Mistakes To Avoid
- Checking a variable changes its value.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
A variable's value can be changed according to a condition. Physical inputs can be tested as part of conditions in if...then...else statements.
2. Define this computing term and give one practical example. 'input'
data that is sent to a program to be processed. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Checking a variable changes its value. Correction: Reading a variable's value doesn't change it, only assigning it does.
