Values Are Not Taught, Values Are Built

Forming values to contribute to the complete formation of the human being as responsible citizens is an educational task that is indispensable to the construction of sustainability. Consequently, this document states that achieving a construction of values that leads to true development is not possible without a teaching and learning of science that, starting from an intersystemic and therefore complex vision of the world, allows us to build them. Answering the question How can interdisciplinary science teaching contribute to generating in today’s children a genuine interest in the study and knowledge of science in general, and in the conservation of natural resources in particular? Was the objective of the methodological proposal for interdisciplinary science teaching that was previously described in the article “Teaching soil science: a strategy and warranty towards the future” ( Reyes-Sánchez, 2012 ). This second document addresses why, how and for what purpose the formation of values and principles accompanied this methodological proposal for interdisciplinary science teaching as a qualitative pedagogical approach that was applied within two schools with children in 5th and 6th grade of basic education −10 and 11 years of age-: by amalgamating the construction of knowledge with that of values to support the appropriation of both in a playful way, seeking and encouraging in children the congruence between knowledge, thought and action. The differences in children’s opinions regarding life problems that affect the social, political and economic order before and after the pedagogical intervention are presented in a comparative manner.
