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


Grade 8

Investigates:


  • background

context

  • Existing

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

  • Practical

tests / testing

  • Data

handling (collect, extract, summarise, presents and

uses the information to justify and support decisions)

Systems & Control:


    Mechanical advantage -in terms of how movement and force is influenced-(mechanical systems, hydraulic & pneumatic included)

    • Drawing

    system diagrams

    • Input

    - Process - Output


      “AND” & “OR” logic. (more than one input / control device)

      • Input

      - Process – Output

      • Drawing

      circuit diagrams

      • Representations

      using Truth tables

      • Drawing

      system diagrams

      Impacts:


        technological products

        (Express detailed opinion for positive and/or negative effects on quality of people’s life & on the environment)



        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 and/or modeling)

            Processing :


            • Forming,

            Shaping or Conditioning a material by adapting them for particular purposes (increased strength, withstand forces, etc.)

            Biases :


              Human rights

              (Opinions backed by factual evidence on effect of technology solutions)

              Makes :


              Planning

              Materials list

              Tools list

              Construction techniques

              Design adaption

              Safety, material and tool use

              Structures:


              Frame Structures :

              • Structural

              components.

                Reinforcing techniques

                  Stability (as in grade 7)

                  all within the context of FRAME structures

                  Indigenous Technology:


                  • Cultures

                  (Comparison of ways of solving similar problems in terms of their belief/value system)

                  Evaluates:


                  • identifying

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

                  • Use

                  (given) 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 for particular target audience
