Teaching unit for teaching the concept of mixtures and solutions from a Developmental perspective
Developmental Didactics; Guiding Base; Chemistry Teaching
This research is characterized as a training experience with the objective of characterizing the influence of a didactic unit for teaching the concepts of chemical solutions in a context of chemistry classes in a high school, which adopts the Planned Training Theory as a theoretical framework. of Mental Actions and Concepts, due to the possibility of following both the process of assimilation of concepts and the methodological didactic planning related to the development of an educational product focused on didactics applied to the teaching of chemistry. Methodologically, it is structured around the elaboration of a guiding reference scheme, adopted as the scheme of the complete guiding basis of action (EBOCA), which presupposes the desired orientation for teaching planning due to characterizing the maximum degree of generalization about the concept. of solutions applied to the secondary education level. As a result, it presents the diagnostic aspects and the process of restructuring student guidance based on the execution of a didactic unit. The results bring qualitative aspects of the change in orientation, which, despite not constituting a reconfiguration of the orientation in its entirety, enable a discussion in relation to the influence of developmental didactics in the context of the formation of chemical concepts.
