Research and development in the teaching and learning of discrete mathematics

Discrete mathematics occupy a rather variable place in math education : in some countries, only a very small number of discrete mathematics concepts are taught, except perhaps those related with combinatorics and the basics of number theory. In a few other countries, for example in Hungary (as far as Europe is concerned), there has been a long tradition to introduce graph theory in secondary schools.

The TSG-15 group aims at collecting researches on math education in its aspects pertaining to discrete mathematics : teaching and learning strategies, for students at different levels, and training of teachers. Discrete mathematics can be introduced, either as a mathematical theory, or as a set of tools to solve problems (a graph is a basic and intrinsic modelling tool). For example, mathematical games are often based on problems in discrete mathematics.

The group will try to assess and analyze collectively the state-of-art of curricula in discrete mathematics. This leads to two general and fundamental questions :

- Why and how introduce discrete maths in schools ?

- How can discrete mathematics contribute to make students acquire the fundamental skills involved in defining, modelling and proving, at various levels of knowledge ?

The TSG-15 group will try to focus on short presentations which present original considerations about number theory, discrete geometry, or graph theory, in a didactical point of view, accompanied, wherever possible, by experimental results concerning student productions and the difficulties encountered.

call for papers

The group will be particularly interested in papers related to the following themes :

-number theory at the elementary school level and for pre-service education of teachers,

-combinatorics and graph theory in the current training of junior college teachers,

-the use of the concept of graph in problems which involve defining, modelling and proving,

–the rôle of discrete maths in mathematical games.

Deadlines

The deadline for submissions is the end of January.
Information about acceptance of the submissions, with recommendations for the final version(8-10 pages), will be available by the end of February.
Final versions should be sent by April, 20th, 2008.
