Asssessment

LO 1

Technological Processes and Skills

The learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies.

We know this when the learner:

investigates:

1.2 finds out about existing products relevant to a problem, need or opportunity, and identifies some design aspects (e.g. who it is for, what it looks like, what it is for, what it is made of).

1.3 performs, where appropriate, scientific investigations about concepts relevant to a problem, need or opportunity using science process skills:

planning investigations;

conducting investigations;

processing and interpreting data;

evaluating and communicating findings.

designs:

1.4 writes or communicates, with assistance, a short and clear statement (design brief) related to a given problem, need or opportunity that demonstrates some understanding of the technological purposes of the solution;

1.5 suggests and records at least two alternative solutions to the problem, need or opportunity that link to the design brief and to given specifications and constraints (e.g. people, purpose, environment);

1.6 chooses one of these solutions, giving reasons for the choice, and develops the idea further.

makes:

1.8 uses suitable tools and materials to make products by measuring out, cutting or separating, shaping or forming, joining or combining, and finishing the chosen material.

evaluates:

1.10 evaluates, with assistance, the product according to the design brief and given spesifications and constraints (e.g. people, purpose, environment), and suggests improvements and modifications id necessary;

1.11 evaluates the plan of action followed and suggests improvements and modifications if necessary.

communicates:

1.12 produces labelled two-dimensional drawings enhanced with colour where appropriate.

LO 2

Technological Knowlede and Understanding

The learner will be able to understand and apply relevant technological knowledge ethically and responsibly.

We know this when the learner:

structures:

demonstrates knowledge and understanding of how materials can be processed to change or improve properties (e.g. strength, fire resistance, waterproofing, taste, volume, texture).

LO 3

Technology, Society and the Environment

The learner will be able to demonstrate an understanding of the interrelationships between science, technology, society and the environment.

We know this when the learner:

Indigenous Technology and Culture:

3.1 recognises how products and technologies have been adapted from other times and cultures.

Impact of Technology:

3.2 suggests ways to improve technological products or processes to minimise negative effects on people and/or the health of the environment.
