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
