Lesson ideas The Student Book and Teacher resources have been designed to be used flexibly, either off-the-shelf in their printed format, or they can be easily adapted and customised by the teacher to better meet the needs of individual classes. In this unit, you will find an outline of lesson ideas and suggestions for learning activities for Unit 1.2.3. This unit introduces students to a range of evaluation techniques that can be used when required in their project. Encourage students to select the most appropriate evaluation technique when conducting an evaluation. One lesson can be devoted to this unit. However, encourage students to use these evaluation techniques throughout the design process, not just at the end.
Lesson starter suggestions Group discussion (SWOT analysis): Source a range of products previously made by students or products made commercially if no previous work is available. Give one product to each group of students and ask them to consider the following: ● Strengths: What advantages does the product have? What does it do better than anything else? What would make you buy it? ● Weaknesses: What could you improve? What could prevent the product from selling? ● Opportunities: Could new technology be used to improve the product? Could the product be made more cheaply? Could it be made more pleasing aesthetically? ● Threats: Are there better products available? Do any safety standards or legislation have to be met? Hand out blank sheets of A3 paper and ask students to draw a SWOT table as on page 30 of the Student Book. Groups record any findings under the relevant sections on their SWOT analysis.
Main lesson activities Skills activity (page 31): Students work in pairs for this activity. They could use a product in the classroom or in their bags. The activity should lead to a discussion about why evaluation should occur at all stages of the design process. Evaluation techniques: Ask students to read pages 30–31 of the Student Book to familiarise themselves with different evaluation techniques. Give them the opportunity to use as many evaluation techniques as possible on their own designs and also use them to get feedback on their designs
