Assessment

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:

1.1 finds out about the background context (e.g. people, environment, nature of the need) when given a problem, need or opportunity and lists the advantages and disadvantages that a technological solution might bring to people;

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;
  • 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;

1.7 outlines a plan that shows the steps for making, including drawing or sketches of main parts;

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

1.9 works neatly and safely, ensuring minimum waste of material;

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

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

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:

2.3 demonstrates knowledge and understanding of how to use energy sources to power mechanical systems in order to make a product move in some way.

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:

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

3.2 identifies possible positive and negative effects of scientific developments or technological products on the quality of people’s lives and/or the health environment.

diameter should be 100 mm distance on compasses therefore 50 mm

2.

distance on compasses 30 mm

Assignment 11

Result is determined according to sketch

Assignment 12

Evaluate how accurately learner has done this with reference to the following questions:

  • Was the size of the drawing determined?
  • Were the parts drawn as a group?
  • Were the correct measuring instruments used?
  • Were the circles and curves drawn in proportion?
  • Were the details completed?
  • Were unnecessary lines erased?

Assignment 13

The teacher can determine the mark by appraising the learner in terms of his/her own impressions of his/her work.
