Flipped classroom

What research says

The idea of flipped classroom is to let the learners study the lesson at home, then, once in the classroom, ask the teacher questions on specific points not fully understood and practiced with exercises. The lessons can be a text, but most of the time the flipped classroom is supported with an approximately 10 min. video lesson.

Project based learning

What research says

Students study topics they will not likely learn outside of school. Most of the time, the learned topics are disconnected; students do not see the connection between these different topics or how they are related. Project-based learning tries to address this problem.

Learning by doing

Taking a closer look at the often-cited innovative pedagogical approaches helps revisit the design of the Dynabook concept; expanding it from the constructivism approach to a broader and more diverse way of teaching and learning. The writing of this paper is deeply influenced by the A. Tricot study, Innovation pédagogique, 2017 on what is considered innovative pedagogy.

The Dynabook and its learning models

Children using the proposed Dynabook (c) Alan Kay On learning-by-doing...

In Alan Kay's Dynabook it is best to learn something kinesthetically, then iconically, and finally the intuitive knowledge will be in place to allow the more powerful but less vivid symbolic processes to work at their strongest(Kay1990).

What said scientific studies on the field of learning by doing and other related pedagogical approaches?

Model with perpendicular bisector

How to resolve a real world problem with perpendicular bisector?

Mathematics is the tool of the mind to build simplified model of a real world problem situation. Then within its model, the mathematics toolset helps to build solutions. We present in the following paragraphs a very simple example of this process with the use of the Dr. Geo software.

Construire la trajectoire parabolique d'un objet soumis à la gravité

Lorsque vous lancez un objet, sa trajectoire est une parabole. Comment est-ce que sa vitesse instantanée et ses composantes verticale et horizontale varient-elles au cours de la trajectoire ? Que se passe-t-il lorsque la vitesse initiale est plus grande ? Plus petite ? Que se passerait-il si la gravité était plus importante ? Plus faible ? Nulle ? Négative ? Avec une gravité et une vitesse initiale constantes, comment lancer l'objet pour lui faire atteindre le point le plus loin à l'horizon ? Dans cet article nous présentons un modèle pour explorer ces questions.

Fibonacci spiral

The Fibonacci spiral is based on the Fibonacci sequence to construct a curve forming a spiral. This spiral and some variants appear in the constructions of live entities. In this article we present a computed, interactive version of this spiral with the help of Dr. Geo, an interactive geometry and programming application. Later we discuss on the interest of this approach in mathematics secondary teaching.

La spirale de Fibonacci

La spirale de Fibonacci s'appuie sur la suite éponyme pour la construction d'une courbe en forme de spirale, cette spirale et ses variantes apparaissent dans des constructions du vivant. Dans cet article nous proposons une construction calculée d'une forme interactive de cette courbe, à l'aide de Dr. Geo, logiciel de géométrie interactive et de programmation. Nous relaterons ensuite les liens à faire avec les programmes d'enseignement secondaire de mathématiques.
