Table 2 Coding scheme of engineering design behavior
Behavior code | Description | Coded example of student’s reflection |
|---|---|---|
IN: Identify need | Identify basic needs (purpose and reason for design) | We made this thing for the balloon-stabbing game |
PD: Problem definition | Define what the problem truly is, identify the constraints, identify the criteria, reread the problem statement or information sheets, and question the problem statement | We needed to be fast, because there were only five minutes |
GATH: Gather information | Search for and collect information | Designed this requiring the use of scientific and theoretical foundations |
GEN: Generate ideas | Develop possible ideas for a solution, brainstorm, and list different alternatives | We tried to design the robot with four pieces of gear |
MOD: Modeling | Describe how to build an idea, measurements, dimensions, and calculations | Added four Yakult bottles near the balloon |
FEAS: Feasibility analysis | Determine workability: does it meet constraints, criteria, etc. | Tried to see which parts were stuck |
EVAL: Evaluation | Compare alternatives and judge options: is one better, cheaper, or more accurate? | Our tires were stable |
DEC: Decision | Select one idea or solution among alternatives | Our current model is a tank |
COM: Communication | Communicate the design to others and write down a solution or instructions | Drew the wheel with 123Design |
IM: Implementation | Produce or construct a physical device, product, or system | During the battle, our team used a wood board to hit |
