Abstract
The purpose of this explanatory paper is to explain material understandings as they relate to a technological product, clarify why and how materials are selected and how they allow technological products to work the way they do. It presents the component descriptor, the key ideas underpinning it, and illustrative examples of these from technology. This paper also suggests possible learning experiences.
Component descriptor
Technological products are material in nature and exist in the world as a result of human design. Understanding the relationship between the composition of materials and their performance properties is essential for understanding and developing technological products. Technological knowledge within this component includes the means of evaluating materials to determine appropriate use to enhance the fitness for purpose of technological products. It includes understandings of how materials can be modified and how new materials are formulated. Understanding the impact of material selection and development on the design, development, maintenance, and disposal of technological products is also included.
