Computational Thinking and Programming (WJEC)

Problem-Solving

Involves understanding problems, breaking them into manageable parts, and developing computational thinking skills.

Computational Thinking

Representing problems as algorithms, decomposing large problems, and focusing on abstraction.

Variables

Store data that can change, with different types like local, global, static, and dynamic variables.

Constants

Store data that does not change, using self-documenting identifiers.

Algorithms and Sorting

Set of clear, ordered instructions to solve problems, including different sorting algorithms like Merge Sort and Bubble Sort.

Searching

Involves Linear Search (sequential comparison) and Binary Search (divide and compare middle item).

Program Testing

Importance of testing for ensuring program functionality, with types like Unit Testing, Integration Testing, System Testing, Acceptance Testing, and Regression Testing.

Program Maintenance

Includes Corrective, Adaptive, Perfective, and Preventive maintenance to ensure program reliability and performance.

Documentation

User Documentation for end-users and Technical Documentation for developers, including code comments and design documents.

Version Control

Tracks changes in the program, manages multiple versions, and enables collaboration using tools like Git and SVN.

Code Review

Regularly reviewing code with peers to catch bugs early and improve code quality.
