The purpose of Technological modelling is to support students to test their design ideas, make decisions to make them more successful, and begin to understand the wider impact of their outcome.
There are two types of technological modelling:
- Functional modelling is the ongoing testing of design concepts (ideas) to see if they work/function as intended
- Prototyping (literally, “creating the first of a kind”) is the realisation of a fully functioning model using the actual materials
Taken together, the two types of modelling provide evidence of factors that may impact on, and consequences that may result from, the student developing a technological outcome.
When students undertake Technological modelling you should see two kinds of reasoning or critical thinking:
- Functional reasoning – how to make it happen, how it is happening
- Practical reasoning – should we make it happen? should it be happening?
Indicators of progression
The indicators of progression describe the knowledge, skills, and understandings that students should be demonstrating in the Technological modelling component of the Technology learning area.
Indicators are provided for each level of the curriculum and are accompanied by guidance for teachers.
In these videos students talk about functional modelling and how they used modelling in their projects.
Students at Te Kura o Otangarei used modelling in cardboard to design a shade house.
A year 13 student created functional models and a prototype for an easily transported ice cream maker.
A keen recreational diver and year 13 technology student developed a tool to measure pāua. The project required extensive functional modelling.
