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


Grade 9

Investigates:


  • identify

& explain problem, need or opportunity in context

  • Existing

products - analyses - (relevant to problem and based on specified design aspects)

  • Practical

tests / testing

  • Data

handling (Locate, collect, compare, sort, verify, evaluate, store, presents and uses the information to justify and support decisions)

Systems & Control:


  • Analyse

systems and sub- systems

  • Drawing

systems diagrams

  • Combining

different sub- systems to create systems.

  • Input

- Process – Output


  • Components

of electronic circuits.

  • Reading,

Drawing & Building electronic circuits.

  • Input

- Process – Output

  • Drawing

system diagrams


Impacts :


technological developments

(Recognise & identify impacts on society/ environment and suggest strategies to reduce any negative impacts)



Designs:


Design brief

Lists specifications and constraints based on specified design aspects.

  • possible

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

  • choice

of solution with reasons

  • chosen

solution developed further -(graphics)


Processing:



  • Preservation

of materials (galvanised, frozen, dried, painted, varnished, electroplated)

Manufacture of products from recyclable materials.

Biases :


Human rights

(Opinions backed by factual evidence on technological decisions and suggest strategies for redress)


Makes :


Planning

Materials list

Tools list

Construction techniques

Design adaption

Safety, efficient material and tools use



Structures :


  • Effect

in performance of materials based on their properties

  • Analysis

of the effect of loads.

Indigenous Technology:


  • Cultures

(Compare and explain global (world) adaptation of technological solutions for optimal benefit)

Evaluates:


  • identifying

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

  • Generating

and using (own) objective criteria

  • 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 for particular target audience
