Elementary level
As elementarization steps to specify the categories of simplification ( elementarization ) of a fact that from physics didactic point of view are allowed.
stages
There are three levels of elementization:
- Limited to the principle of experiment
- Phenomenological order
- Theories in the sense of mathematisations
example
Example of elementary levels using the example of physical work:
- A restriction to the principle of experiment would, for example, be the equivalence of energy and work, i.e. energy = work. In principle, both terms can be used in the same place, although they describe two different facts.
- Work = force · way would be a simplification of the phenomenological order if one were to forego the formula and the qualitative context of the law. For example, one then teaches that the more strength I need, the more work I have done.
- The following simplification can be described as a theory in the sense of a mathematization: The work is the path integral over the vector field of the force. Here one does without an idea and simplifies the connection to a mathematical formula.
