SHS1 Manufacturing Engineering · Semester 1 Week 13: Design and Drawing for Manufacture

Lesson notes

Learning Objectives

Indicator: 1.2.1.LI.3 - Demonstrate understanding of the design process.

By the end of the lesson, learners can:

State the eight stages of the design process in their correct order.
Apply the design process to define a community problem and generate at least three alternative conceptual solutions.
Use simple evaluation criteria to select the most suitable solution from a set of options and justify their choice.
Work collaboratively in mixed-ability groups to produce a design process proposal for a typical Ghanaian community problem.
Present their group solution to the class and respond respectfully to constructive critique from peers.

Curriculum details

Strand: Design and Prototyping (Strand 2)
Sub-strand: Design and Drawing for Manufacture (2.1)
Content standard: 1.2.1.CS.1 - Demonstrate knowledge and skill in the development of surfaces. 1.2.1.LO.1 Use drawing instruments properly to draw the borderline and title block for a drawing. 1.2.1.LO.2 Apply the principle of development of surfaces to develop products. 1.2.1.LO.3 Explain the use of the design process in solving problems. 1.2.1.LO.4 Use freehand sketches and visualisation of objects to express a design idea.
Indicator: 1.2.1.LI.3 - Demonstrate understanding of the design process.
Suggested placement: Semester 1, Week 13 (Week 13 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Talk for Learning: Using a typical problem in the community, lead learners to discuss the design process, focusing on;
- Defining the problem
- Research/asking questions to understand the problem
- Brainstorming potential solutions (conceptual designs)
- Deciding on a solution using evaluation criteria essential to the solution
- Developing the solution
- Making a prototype of the solution
- Testing the prototype
- Improving the design based on results from the test
Experiential Learning: Learners in mixed-ability groups use the design process to propose solutions to a typical problem in their community and present their solutions to the class. Groups critique what others have done in a respectful and tolerant manner.
