Our concern is how to make our education system and teaching-learning an appropriate and consistent process to
meet these challenges and make the teaching of chemistry in schools a Moroccan lever of development of science
and scientific research faced with a lack of human and material.
How should we disseminate scientific culture within a population of students who live in an environment of phase
with this culture? How can we solve the problem of motivation and ambition, all motor development among both
teachers and students, as leaders in educational action?
In this vein, what has happened to the effectiveness of the current teaching of chemistry? And to what extent
teaching succeed in mission to reorganize and enrich the conceptual domain of students, especially in the basic
concepts of chemistry, mainly chemical reactions? What practices and methods are used for the teaching of
chemistry in Moroccan high schools? Do these practices manage to introduce the students involved to the modeling
process and provide for their perceptions and representations correctly? What structure is suitable for teaching and
learning through which students can learn to properly use models and modeling in chemistry? Students they differ
empirical models and register. Do they distinguish between a chemical change and chemical reactions that allowthe
model? Do students verify that they sense that evolution under the criterion is consistent with the initial empirical
situation?
The paradox
