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 and Output


  • Components of electronic circuits.
  • Reading, Drawing & Building electronic circuits.
  • Input - Process and 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
