The Newton-Raphson Method

The Newton-Raphson method is a very efficient algorithm to search for the zero of a real function. Most of the time it converges more quickly than a dichotomy approach. Nevertheless, there are some traps to avoid by studying the function and/or its curve.

La méthode de Newton-Raphson

La méthode de Newton-Raphson est un procédé très efficace dans la recherche du zéro d’une fonction réelle, sa convergence est généralement bien plus rapide que celle de la méthode dichotomique. Elle comporte cependant des chausse-trappes qu’une étude de la fonction et de sa courbe permettent d’éviter.

Dynabook, user interface point of view

In our previous writings, we took the point of view of said innovative teaching approaches. It differs from the children's point of view historically taken by A. Kay. This provided us a set of general features, curriculum neutral, we may want for a teacher centered Dynabook; we summarize it in our "Dynabook and learning models, final words" writing.
