BGCSE Design & Technology study guide
BGCSE Design & Technology · Work through your exam, one topic at a time.
The BGCSE Design & Technology is a secondary-school qualification in the Bahamas, typically taken by students near the end of their compulsory schooling and used for further study, employment, or technical training. It suits candidates who enjoy solving practical problems: turning a brief into a workable design, choosing materials sensibly, making the product, and explaining the decisions along the way. The BGCSE Design & Technology study guide has 9 sections and about 2,756 words.
01Design Process and Problem Solving
The design process is rarely a straight line. A candidate must know the stages: identifying a need or problem, writing a design brief, producing a specification, generating and evaluating ideas, developing a chosen solution, planning manufacture, making, testing and evaluating.
337 words, about 2 min02Materials and Their Properties
Know the main families: hardwoods (oak, ash, mahogany), 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) and composites (GRP, carbon fibre). For each, understand density, strength, hardness, toughness, elasticity, malleability, ductility, conductivity and resistance to corrosion.
296 words, about 1 min03Tools, Equipment and Workshop Safety
Know the purpose of marking-out tools (try square, marking gauge, scriber, centre punch), cutting tools (tenon saw, coping saw, hacksaw, chisels, files), and shaping tools (planes, rasps, abrasive papers). Match the tool to the material: a hacksaw for metal, a tenon saw for timber, a junior hacksaw for small tube.
326 words, about 2 min04Manufacturing Processes and Techniques
Know material-removal processes (sawing, drilling, turning, milling, filing), forming processes (bending, casting, vacuum forming, injection moulding, extrusion) and joining methods. Permanent joints include welding, brazing, soldering, riveting and adhesives; temporary or semi-permanent joints include screws, bolts, nuts and knock-down fittings.
300 words, about 2 min05Technical Drawing, Sketching and Communication
Know the difference between sketching (freehand, for ideas) and formal drawing (accurate, to scale). Understand orthographic projection: front, plan and side views arranged in first-angle or third-angle projection, with hidden detail as dashed lines and centrelines as chain lines.
286 words, about 1 min06Structures, Mechanisms and Control
Understand that structures carry loads and transmit forces. Know the types of load (tension, compression, bending, torsion, shear) and the members that resist them: ties in tension, struts in compression, beams in bending.
315 words, about 2 min07Energy, Electricity and Electronics
Distinguish renewable from non-renewable sources and know that energy is transferred, not used up. Understand efficiency as useful output divided by total input, expressed as a percentage, and that losses usually appear as heat or sound.
295 words, about 1 min08Design in Society, Sustainability and Ethics
Design affects users, workers, communities and the environment. Candidates should discuss ergonomics, anthropometrics, accessibility and inclusive design, and the difference between designing for the average user and designing for extremes.
305 words, about 2 min09Practical Project and Coursework
A practical project is assessed across identifying the problem, research and analysis, specification, design ideas, development, planning, making, testing and evaluation. Each section must be evidenced with photographs, sketches, data and annotation.
