RESUMO

This research, whit the design and implementation of contextualized laboratory activities in chemistry was carried out, in order to demonstrate the level of argumentation presented by teachers in initial training, first semester of the Bachelor of Natural Sciences program and Environmental Education of the Pedagogical and Technological University of Colombia “UPTC”. This research was developed with a qualitative, interpretive and phenomenological research approach, allowing us to observe the progress presented by the students under study, in terms of argumentative processes, taking as reference Toulmin who describes different levels of argumentation. The research was carried out in three phases: a diagnostic phase that allowed identifying the initial state of the teachers in training, a second phase of design and implementation of the sequence of activities based on situations of context, and finally a third evaluation phase in which the levels of argumentation reached by the students, having as a fundamental basis the triangulation of data between the experiences of the students confronted with theoretical references that would allow us to account for the results found. It was possible to identify the difficulty that students present when preparing structured arguments as proposed by Toulmin, demonstrating the lack of appropriation of scientific language that students have and the low development of this competence at the different levels of academic. Is important to promote the use of different didactic strategies such as experimentation in the classroom, which allow strengthening the different argumentation processes in students.
