Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit introduces pupils to the new data structures of records and dictionaries. They will develop a Caesar cipher encryption program using a dictionary as a cipher wheel. Pupils will explore how data can be read from and written to files and how this data can be used within a program.
Lesson Summary
You will learn to implement and evaluate a solution using success criteria.
Key Notes
- A code log is a document that you can use when developing a program to keep track of your progress.
- Success criteria are the benchmarks that your project will need to meet in order for it to be a success.
- Success criteria can also be used to complete the final testing of your program.
- Evaluation happens after the program has been made and tested.
- Evaluation is about judging how well the program meets the original success criteria or requirements.
Vocabulary To Learn
- code log: a document that you can use when developing a program to keep track of your progress throughout the project
- success criteria: specific, measurable and realistic benchmarks used to determine if a project, task or outcome has been accomplished successfully
- evaluation: reflecting on what has been done well and what could be improved
Common Mistakes To Avoid
- Once a program has been developed, it is finished and there is no need to evaluate or reflect on what you have done.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
A code log is a document that you can use when developing a program to keep track of your progress. Success criteria are the benchmarks that your project will need to meet in order for it to be a success.
2. Define this computing term and give one practical example. 'code log'
a document that you can use when developing a program to keep track of your progress throughout the project. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Once a program has been developed, it is finished and there is no need to evaluate or reflect on what you have done. Correction: Evaluation is about judging how well the program meets the original success criteria or requirements. It can help you to revisit and make improvements to a program, as well as reflect on lessons learnt for your next project.
