Comparisons of old and new methods

 

Working by Calculating Rules

Idea and Meaning

Determination of tangent inclinements and derivatives by syntactic rules

Derivation as idea of transition from the average to the local changing rate

Integration for the concrete calculation of areas and of integral functions by syntactic rules

Integral as idea of reconstructing a function from local changing rates

Performing the Newton procedure by a pocket calculator or a computer

Idea of approximation of zeros by an iteration procedure and analysis of the convergence behaviour

“Curve sketching” as application of calculating rules to function and their derivatives

“Curve sketching” as capable analysis of properties of functions

Formal solving of systems of equations

Representation of geometric figures (straight lines, planes, circles, ellipses,…) by the aid of analytical methods

 

Mathematics as a Product

Mathematics as a Process

Putting over a calculus procedure and it’s application

Developing a calculus procedure and understanding of it

Communicating knowledge, putting over connections

Set-up of knowledge, discovering of connections

To aim at self contained problems

Deliberately allow openness

From the structure to the application

From the problem to the structure

Study a given model

Modelling reality

Isolated problems with unique solution

Fields of problems in a network with versatile solutions

To give notions, to prove theorems formally

To develop notions, to find theorems, to demonstrate plausibly

Convergent and result oriented guidance during the class

Open process oriented guidance during the class

Mistakes as a sign of insufficient capability of the product

Mistakes as a source of constructive improvements

 

Further point, promoted in Adolf J I Riede, Mathematical modelling as an integrated part of the class on calculus:

 

 

Lack of understanding a sign for missing ability

Lack of understanding as a source of didactical improvements
