| Learning Outcomes(LOs) |
| LO 1 |
| TECHNOLOGICAL PROCESSES AND SKILLSThe learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies. |
| Assessment Standards(ASs) |
| We know this when the learner: |
| investigates : |
| 1.1 investigates the background context, the nature of the need, the environmental situation, and the people concerned when given a problem, need or opportunity set in a local context; |
| 1.2 examines existing products relevant to a problem, situation or need. |
| 1.3 investigates by performing simple practical tests relating to aspects of the technological knowledge areas (Structures, Processing, and Systems and Control); |
| 1.4 during investigations, plans a strategy for collecting data and information. |
| evaluates : |
| 1.12 evaluates the product or system based on criteria linked directly to the design brief and some of the specifications and constraints, and suggests improvements or modifications; |
| LO 2 |
| TECHNOLOGICAL KNOWLEDGE AND UNDERSTANDING The learner will be able to understand and apply relevant technological knowledge ethically and responsibly. |
| Assessment Standards(ASs) |
| We know this when the learner: |
| processing :2.2 demonstrates knowledge and understanding of how materials can be processed to change or improve properties (e.g. strength, fire resistance, waterproofing, taste, volume, texture). |
