Abilities for a Technological World
What the domain covers
Abilities for a Technological World covers what practitioners do with technology: troubleshoot, research, invent, innovate, maintain, assess impacts, and use tools safely. Items test systematic procedures and safety reasoning.
Core rules
- Troubleshooting is systematic diagnosis: gather symptoms, form hypotheses, isolate variables, test one change at a time, verify the fix, and document.
- Research and development moves from inquiry to prototyping; experimentation requires controlled variables and repeatable measurement.
- Invention creates something new; innovation implements and diffuses it. Reverse engineering analyzes an existing product to learn its principles.
- Maintenance is preventive (scheduled) or corrective (after failure). Documentation supports repeatability and safety.
- Impact assessment compares risks and benefits, including who bears them.
- Tool safety requires correct PPE, guarding, lockout/tagout during repair, and knowledge of material hazards.
Worked example
A 3D printer jams mid-print. Symptoms: under-extrusion and a grinding sound. Hypotheses: tangled filament, wrong temperature, clogged nozzle, or too-low idler tension. You test one variable at a time-first checking filament feed, then temperature, then cleaning the nozzle-and find a partial clog. You clear it, run a test print, and log the cause and fix. This is troubleshooting, not redesign.
Traps that cost marks
Changing several variables at once; skipping documentation; calling any repair troubleshooting when no diagnosis occurred; and ignoring lockout/tagout or PPE to save time.
