KEY CONCEPTS, KEY FOCUS and IMPLICATIONS for TEACHING & LEARNING of Technology through the RNCS

Grade 7

Investigates:


  • background

context

  • Existing

products - examine- (relevant to problem and based on key design aspects)

  • Practical

tests / testing

  • Data

handling (plan, collect, extract, copyright laws, summarise & present)

Systems & Control:


  • Changing

direction of movement and/or the value of force (using the components of mechanical systems, hydraulic and pneumatic included)

  • Input

- Process - Output

  • Drawing

system diagrams.


  • Series

and parallel electrical circuits ( with more than one output device)

  • Input

- Process - Output

  • Drawing

system diagrams

Impacts:


technological products

(Express reasons for positive and/or negative effects on quality of life)


Designs :


Design brief

Lists specifications and constraints based on specified design aspects.

  • possible

solutions- alternative- (linked to design brief & specifications and/or constraints.)

  • choice

of solution with reasons

  • chosen

solution developed further -(graphics or modeling)

Processing:


Conditioning a material to change or improve specific properties (strength, fire resistance, waterproofing, taste, volume, texture, etc.)


Biases :


technological products

(Express opinion on advantage or disadvantage on certain sectors of society)

Makes :


Planning

Materials list

Tools list

Construction techniques

Safety, material and tool use


Structures:


Use of materials in structures based on their properties.

Stability in terms of size, shape & form

  • Strengthening

parts of and/or complete structures

Indigenous Technology:


  • indigenous

cultures in South Africa (Explain the use of specific materials with reasons for the differences)

Evaluates:


  • identifying

Strengths and weaknesses of: Product , System and of plan of action

  • Use

criteria for evaluation

  • suggestions

for improvement / modification




Communicates:


  • 2D

(1st / 3rd angle) or 3D (isometric, perspective, oblique)

  • enhanced

sketches / drawings (colour/ shading/ rendering)

circuit diagrams (circuit symbols)

systems diagrams (input, process, output)

  • notes,

labels, dimensions, list of quantities.

SA drawing conventions (for above)

Appropriate use of Technology to present information.
