Una cuestión socioambiental entorno al río Tunjuelito en la enseñanza de la química; un estudio de caso para la media y la media básica en el IED Antonio Baraya

Abstract

Next, the final results of a global single case study (doctoral thesis) are presented, to qualify for the title of Doctor of Education, which answers the question how to design a didactic unit for the teaching of greenized chemistry from the position of post-conventional moral dilemmas, of 21 high school students who face a real Socio-Environmental Issue (CSA) of the environment of the middle basin of the Tunjuelito River ( CMRT)? The methodology is developed in three phases, each with parts A and B, in which instruments such as role-playing, semi-structured interviews, and social representations are used. In each phase, a cognitive gradation is obtained for the construction of moral dilemmas that in the final stage will be used as cognitive elements proposed to serve as harmonizers between the tensions of the CSA and the positions of secondary school students when interacting with the concepts of chemistry in said didactic unit
