Effective learning about the reflection of light

Since its independence, Benin has made the education sector a national priority. The institutional framework of education has varied according to the political changes that have taken place in the country's contemporary political history, but the priority given to this sector has never been denied by successive governments. The actors of the Beninese education system have made a total and decisive commitment to train qualified, competent teachers, animated by a spirit of method, capable of giving knowledge to learners. It is in this perspective that the reopening of the Ecoles Normales Sup rieures has been a reality. The ENS of Natitingou, for example, has the mission of ensuring the initial and continuous training of assistant and certified teachers of General Secondary Education in the fields of Physical Sciences, Chemistry and Technology (SPCT), Mathematics and Computer Science (MI) and Life and Earth Sciences (SVT). The present work has two main parts: -Theoretical axis at the level of which we are going to present the CEG1 of Natitingou; -Practical axis which is the object of our research, reports the development of our theme.
