| Lesson Topic: Quality assurance (QA) checks to be used in the production of a product. (Quality assurance checks are made at every stage of the production process to meet the quality standards set.) |
Learning Objective/s:
- Describe the purpose and benefits of QA checks in product manufacturing.
- Identify appropriate QA checks for each stage of the production process.
- Apply a checklist to record and evaluate QA results during a simulated production run.
- Analyse simple SPC data to determine process capability.
- Explain how corrective actions are documented and implemented.
|
Materials Needed:
- Projector and screen
- Whiteboard and markers
- Printed QA checklist handouts
- Sample product/prototype
- Measuring tools (calipers, micrometers)
- Laptop with SPC software demo
- Worksheet for data analysis
|
Introduction:
Begin with a short video showing a product defect caused by missed QA checks, then ask students to recall any personal experiences with product failures. Review briefly how QA fits into the design‑technology cycle. Explain that today they will learn to plan, execute and record QA checks, and will be assessed through a checklist activity and a reflective exit ticket.
|
Lesson Structure:
- Do‑now (5'): Students list examples of product failures they have seen and share briefly. (5')
- Mini‑lecture (15'): Overview of QA purpose, production stages, and typical checks; show slide with the stage‑wise QA table. (15')
- Guided practice (20'): In groups, students use a sample prototype and measuring tools to perform dimensional inspection and complete a QA checklist for the prototype stage. (20')
- Data analysis (10'): Introduce SPC chart; groups plot sample data, calculate Cp/Cpk and discuss acceptability. (10')
- Role‑play (10'): Simulate a non‑conformance; groups decide corrective action and fill a simple report. (10')
- Plenary (5'): Recap key points; students complete an exit ticket stating one QA check they will apply in future projects. (5')
|
Conclusion:
Summarise how systematic QA checks protect product quality and reduce costs. Collect exit tickets to gauge understanding and assign a brief homework task: each student creates a QA checklist for a product of their choice to be discussed in the next lesson.
