| Abstract: | Technological knowledge has a normative component that scientific knowledge does not have. When we have knowledge of a computer, that often comprises normative judgements: it functions well or it does not function well. In knowledge of technical norms, rules and standards as another type of technological knowledge we also find a normative component. This characteristic has consequences for our assessment of knowledge. For scientific knowledge truth is the ultimate condition. For knowledge of norms, rules and standards as a type of technological knowledge this the condition is problematic. They refer to things that do not exist yet, but are still to be designed or made. Nor truth, but effectiveness is the condition here. For technology education the normative component is important. Pupils must learn to make judgements about effectiveness, as this is a prominent characteristic of technological knowledge, that makes it distinct from scientific knowledge. Pupils must also learn to deal with ethical and other values when doing technological project work. |
