BEC JCE Design & Tech study guide
BEC JCE Design & Tech · Work through your exam, one topic at a time.
The BEC JCE Design & Technology credential is a junior secondary school-leaving qualification awarded by the Botswana Examinations Council. It recognises that a learner can move through a full design cycle - identifying a need, generating and refining ideas, making a product, and judging how well it worked - while understanding the materials, tools and production methods that make a design buildable. The BEC JCE Design & Tech study guide has 7 sections and about 1,788 words.
01Design Process and Problem Solving
Candidates should be able to describe and apply the stages of a design process: identifying a need or problem, writing a design brief, producing a specification, generating and evaluating ideas, developing a chosen concept, planning and making, testing, and evaluating against the original brief. Understand that the process is iterative rather than linear - testing often sends you back to generate or refine ideas.
286 words, about 1 min02Materials and Their Properties
Candidates must classify materials as hardwoods (oak, ash, beech), softwoods (pine, spruce), manufactured boards (plywood, MDF, chipboard), ferrous metals (steel, cast iron), non-ferrous metals (aluminium, copper, brass), thermoplastics (acrylic, HDPE, polystyrene), thermosetting plastics (epoxy, melamine), composites (GRP, carbon fibre) and smart/modern materials (shape-memory alloys, photochromic pigments). Understand mechanical properties - strength, stiffness, toughness, hardness, ductility, malleability, elasticity - and physical properties such as density, thermal and electrical conductivity, and resistance to corrosion.
234 words, about 1 min03Tools, Equipment and Workshop Safety
Know the purpose and safe use of marking-out tools (try square, marking gauge, engineer's square), cutting tools (tenon saw, coping saw, hacksaw, chisels, files), shaping tools (planes, rasps, abrasive papers) and assembly tools (clamps, sash cramps, screwdrivers). For machines, understand the drill press, band saw, scroll saw, lathe and sander, and which guards and hold-down devices each requires.
289 words, about 1 min04Manufacturing Processes and Production Techniques
Understand one-off , batch , mass and continuous production and how scale affects tooling cost, unit cost, labour skill and flexibility. Learn the trade-off: high tooling costs suit large volumes because they spread over many units.
245 words, about 1 min05Technical Drawing, Communication and Modelling
Candidates must read and produce orthographic projections (front, plan, side views in first- or third-angle), isometric drawings, and exploded views. Know line conventions: continuous thick for outlines, continuous thin for dimension and projection lines, dashed for hidden detail, chain lines for centrelines and cutting planes.
233 words, about 1 min06Design in Context: Sustainability, Ergonomics and Society
Understand the six Rs - rethink, refuse, reduce, reuse, repair, recycle - and apply life-cycle thinking from raw material extraction through manufacture, use and disposal. Know concepts such as carbon footprint, embodied energy, planned obsolescence, design for disassembly, and renewable versus finite resources.
244 words, about 1 min07Practical Project and Evaluation
Candidates should plan a project with a clear brief, specification, materials list, cutting list, sequence of operations and risk assessment. Understand the importance of a production plan and quality control checks at each stage, and how to record decisions and modifications as the project develops.
