This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit takes pupils from designer to developer in order to create their own mobile app. Using App Lab from code.org, learners will familiarise themselves with the coding environment and have an opportunity to build on the programming concepts they used in previous units to undertake a project.
Lesson Summary
You will learn to make an app with multiple screens and test that it meets user requirements.
Key Notes
- Adding interactivity to an app requires instructions to be added to elements.
- Testing and debugging your code is a key part of any project.
- An app should match the project's goals and user needs.
Vocabulary To Learn
- testing: to check if something works correctly and as expected
- debugging: the process of finding and fixing errors in code to ensure it works correctly
- rubric: a guide that outlines criteria and levels of achievement to evaluate work fairly and consistently
Common Mistakes To Avoid
- Once the app runs it is finished.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
