Charts and Algorithms

Learning Intention

• Apply computational thinking and algorithmic design by defining the key features of standard algorithms, including sequence, selection, iteration and identifying data that should be stored

• Develop structured algorithms using pseudocode and flowcharts, including the use of subprograms

• Use modelling tools including structure charts, abstraction and refinement diagrams to support top-down and bottom-up design

• Analyse the logic and structure of written algorithms

Success Criteria

• I can define, interpret and utilise key features of standard algorithms including sequence, selection and iteration.

• I can interpret and create detailed documentation during the design phase of software development to visually and clearly represent the system, including key components such as diagrams, specifications, and technical descriptions:

  • IPO Charts (Input-Process-Output): These charts outline the flow of data through the system, specifying inputs, processes, and outputs.

  • Flowcharts: Visualise processes and decision points within the system to ensure logical flow.

  • Pseudocode: Provides a high-level representation of the code logic to be implemented.

  • Structure Charts: Used to depict the hierarchical organisation of modules within a program.

  • Data Dictionaries: Essential for defining the data elements and structures used throughout the program.

  • Data Flow Diagrams: A Data Flow Diagram (DFD) visually represents how data moves through a system, showing inputs, processes, storage, and outputs.

  • Class Diagrams: A class diagram in software design visually represents the structure of a system by showing its classes, attributes, methods, and relationships between objects.

  • Storyboards: a visual representation that outlines the sequence of user interactions with a system, typically used to map out user experiences and interface flows.

Each of these documentation types helps to ensure clarity and consistency throughout the development process.
