SAASTE Technology/Key Concepts/Grade 9

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
