For this unit, students choose their own problem to solve. Students will be expected to analyse, design, develop, test, evaluate and document a program written in a suitable programming language. The underlying approach to the project is to apply the principles of computational thinking to a practical coding problem.
Learners are expected to apply appropriate principles from an agile development approach to the project development.
20% of the qualification. Internally assessed.
3.1 - Analysis of the problem (10 marks)
3.2 - Design of the solution (15 marks)
3.3 - Developing the solution (25 marks)
3.4 - Evaluation (20 marks)
