Assessment

Learning outcome 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.

Assessment standard

We know this when the learner:

1.1 finds out, with assistance, about the background context (e.g. people, environment) when given a problem, need or opportunity;

1.2 finds out about existing products relevant to a problem, need or opportunity, and identifies the main design aspect (e.g. who it is for, what is it for, what it looks like) that make them suitable as a solution;

1.4 writes or communicates, with assistance, a short and clear statement (design brief) for the development of a product for a given purpose;

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

1.6 chooses one of these solutions, giving reasons for the choice.

Learning outcome 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.

Assessment standard

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 1 more than 3 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 113?
mariel Reply
Mark = x,. Don = 3x + 1 x + 3x + 1 = 113 4x = 112, x = 28 Mark = 28, Don = 85, 28 + 85 = 113
