La enseñanza problémica en el aprendizaje de las ciencias en el nivel medio

The following article presents as a fundamental objective, to show some simple examples aimed atthe Basic Level in which the main problem methods are used around Natural Sciences, treated as afeasible alternative to achieve active learning where students are not mere spectators or objectsknowledge, but rather, through interaction with the teacher, they feel protagonists of their ownknowledge. The exposed examples do not necessarily have to have complex instruments andtechniques, but, on the contrary; since the very fact of being oriented to the basic elementary school,includes the affordability to any type of student who, in the case of experiments, can resort to easilyacquired materials. Of course, those shown are only examples, and teachers can add others, whichwould enrich their work in the educational teaching process.
