PRESCRIBED LEARNING OUTCOMES

It is expected that students will:

interpret design representations (drawings, plans, schematics) to assist in developing a product or system
use computer programs (including CADD, CAM, CNC) to assist in production and manufacturing processes
apply appropriate production processes (combining, forming, separating, finishing) to create products and systems that conform to:
- specified design criteria (form, function, aesthetics, ergonomics, end-user needs)
- recognized standards, conventions, and tolerances
apply the principles of WCB and WHMIS regulations in their work environment

SUGGESTED INSTRUCTIONAL STRATEGIES

As students modify existing products and develop their own, they learn to safely apply the processes required to develop and improve products or systems to meet community guidelines and standards.

Divide the class into teams. Ask each to design and construct a component for a barrier-free kitchen or bathroom. As they develop their products, encourage them to incorporate a range of natural and composite materials based on their design proposals and feedback from end-users.
Have students develop products that enhance the quality of life for someone with physical limitations (e.g., transportation or walking aid). Before they begin production, ask them to develop plans outlining production processes and safety principles they will apply as they work.
Instruct students about various computer programs that aid production and manufacturing processes (e.g., CADD, CAM, CNC). Guide them in the use of these computer programs to develop products of their choice (e.g., jewellery box, licence plate frame). Have them create design portfolios to track the products´ development from conception to final result. Ask them to ensure that they include the following in their portfolios:
- rationale for their choice of materials
- descriptions of the production processes involved
- discussion of the benefits and limitations of using CADD, CAM, and CNC
- descriptions of the safety strategies they applied

SUGGESTED ASSESSMENT STRATEGIES

As students create products and systems, they can demonstrate their abilities to interpret design representations, use computer programs in production and manufacturing processes, and maintain a safe work environment.

As students produce computer-generated models using appropriate software, note the extent to which they are able to:
- select appropriate techniques
- produce professional-quality models
- effectively represent different materials
- use the models to explain their design ideas
Work with students to establish criteria for assessing their grasping or lifting devices. The criteria could include:
- selection of materials that reflect the requirements of the design proposal
- reduction of material waste in the production process
- quality of the finished product in relation to design criteria
Have students develop design portfolios for a jewellery box that incorporates CADD/CAM/CNC in the production process. Collect their design portfolios and look for evidence that they are able to:
- support their reasons for selecting materials
- produce designs that maximize the potential uses of CADD/CAM/CNC in production versus traditional methods
- identify the limitations of using CADD/CAM/CNC in production
- select the appropriate cutting tools to perform the various machining tasks
After students have watched a video or listened to a presentation by the WCB, ask them to reflect on what they have learned by completing sentence stems such as the following:
- One thing I learned that surprised me was ____________.
- One thing I can do to improve my safety is ____________.
- Two things that can be done to reduce accidents are ____________.
- One thing I am still wondering about is ____________.
