Lesson notes

Learning Objectives

Indicator: 2.1.2.LI.1 - Make use of component diagrams and system diagrams to design non-feedback systems for implementing controls in given scenarios.

By the end of the lesson, learners can:

Identify the standard symbols used in component diagrams and system diagrams for non-feedback control systems.
Explain the difference between a component diagram and a system diagram and state when each is appropriate.
Convert a narrated automated solution into a component diagram showing all inputs, controllers, actuators and outputs.
Convert a component diagram into a system diagram that shows the flow of control without feedback loops.
Design a complete non-feedback control system for a given scenario, justifying the choice of components.

Exemplars (from the NaCCA curriculum)

Initiating Talk for Learning: The teacher leads a discussion to walk learners through design methodologies using component diagrams and system diagrams for designing non-feedback-controlled systems.

Collaborative Learning: Learners work in small, well-balanced groups to design component and system diagrams for given use cases or a narrated automated solution to a problem guided by the following steps:
- Brainstorm to understand the solution
- Discuss candidate design ideas
- Sketch out candidate design ideas on paper
- Choose the best design
- Use standard component and system diagrams to represent the chosen design

Assessment (2.1.2.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 3 Strategic reasoning.
