GACE Engineering and Technology Education (739) case studies
GACE Engineering and Technology Education (739) · Put your knowledge to work in context.
The GACE Engineering and Technology Education (739) assessment is the Georgia content-area test for candidates seeking certification to teach engineering and technology education in the state's public schools. It is intended for aspiring and practicing teachers who will deliver courses covering engineering design, technological systems, and the tools and processes of the discipline, typically at the middle or high school level. The GACE Engineering and Technology Education (739) case studies are 5 cases and about 4,137 words.
1Reframing a Bird-Feeder Rotation as an Engineering Unit
Midway through the fall semester, a first-year engineering and technology education teacher at a rural middle school learns that the long-standing woodshop rotation - students building identical bird feeders from a teacher-supplied pattern - must now be defended as an engineering course. The principal wants evidence that students are engineering, not just cutting wood; the CTE director wants alignment to the state technology education standards; a parent has asked why the class is not real science.

An 11th-grade engineering design class is prototyping insulated carriers for a scenario in which a rural clinic must move 12 vaccine vials at 2–8 °C for six hours. Each team receives one 250 mL frozen gel pack, 1 cm foam, cardboard, reflective bubble wrap, tape, and a digital thermometer; the prototype budget is $8 per team.

The technology student association at a suburban high school runs a device-refurbishing program and collects 48 donated laptops. Students find that 29 boot and can be repaired, 11 need parts averaging 35 each, and 8 are beyond repair.

In a principles-of-engineering class, students design balsa trusses spanning 30 cm and load them at midspan until failure. Instruction covered tension, compression, and joint design; teams used a free truss-analysis app that predicted failure loads from member geometry.

Two teachers co-teach a capstone engineering design course and share a four-criterion rubric - problem definition, design justification, prototype evidence, and communication - each scored 1–4. After scoring 27 portfolios independently, their means differ by 1.5 points on design justification, and they disagree by two points on six portfolios.
