PRESCRIBED LEARNING OUTCOMES

It is expected that students will:

use computer systems to control machines or devices
select and use a variety of input and output devices to achieve specific purposes
construct control systems or robotics devices that connect components, including:
- controller
- manipulator
- end effector
design and construct electronic systems to recognized community standards that incorporate electronic components and development processes

SUGGESTED INSTRUCTIONAL STRATEGIES

As they observe, disassemble, and assemble simple machines and other technological devices, students develop an understanding of the workings of more complex machines.

After students connect and test various circuits (e.g., motion sensor for a light switch), have them demonstrate their understanding of how to integrate controllers, manipulators, and actuators. Ask them to use either a trainer, paper-and-pencil drawings, or a prototype to illustrate integration. As an extension, have students design and construct the devices.
Demonstrate the use of CNC equipment in manufacturing a product. Have students develop a simple product using integrated CAD, CAM, and CNC software.
Present students with tools or simple machines (e.g., electric hand drill, air drill). Ask them to work in teams of three (technologist, end-user, engineer) to critique strengths and limitations of each machine or tool (e.g., size, weight, length of cord) and to describe the safety standards for each (e.g., applicable safety and WCB codes).
Have each student design, construct, and program a robot that will:
- follow a path
- trace a maze
- go in circles
- go up and down
- make two movements
Emphasize that the devices should include controllers, manipulators, and effectors.

SUGGESTED ASSESSMENT STRATEGIES

As students develop machines or devices, they can demonstrate their abilities to select and use a variety of input and output devices to achieve specific purposes.

Have students demonstrate their understanding of how to use software to control a machine or device by making presentations to a group of younger students. Watch for evidence of:
- selection of appropriate commands
- use of correct terminology
- clarity of explanation
Have teams of students role-play consumer groups and analyse a system or device for safety and function. Observe the extent to which students are able to:
- identify industry standards for the system or device
- identify the working features of the system or device
- identify any potentially unsafe features
- suggest realistic ways the unsafe features could be corrected
Collect student-constructed robots that include the use of controllers, manipulators, and effectors. Note the extent to which the robots:
- meet the initial criteria
- function effectively
- perform the predetermined commands
Have students reflect on the safety of one of the electronic systems they have constructed by answering questions such as:
- What codes or standards did you comply with or should have been complied with in the construction or operation of the system or device?
- What modifications could you make to ensure that the system or device is safer for the user?
