The present research had the objective of analyzing the external and internal didactic transposition of the ionic bond content in the context of High School in the Sertão do Pajeú. The notion of didactic transposition, proposed by Yves Chevallard (1991), consists of a process in which knowledge is submitted to a set of modifications, from the academic sphere (knowing wise) to the school environment, in two stages: external (resulting not knowing to be taught) and internal (resulting in the knowledge taught). The research is haracterized asqualitative and was developed in two high schools in the city of Serra TalhadaPE. In this work, the external phase of the transposition was initially analyzed, observing the modifications that the knowledge is submitted to the classroom for the ionic content, investigating the following elements: dessincretization, repersonalization, recontextualization, programmability and publicity. The technique used for data collection was the Bardin Content Analysis (2010). Next, we try to analyze the internal phase of the transposition, observing how two teachers didaticamente transposes the content inside the inner walls of the classroom, analyzing the elements of didactic transposition mentioned above. For the analysis of the elements of the transposition, we are based on the proposal of Brito Menezes (2006), Neves (2009), Guimarães (2009) and Melzer (2012). From the analysis of the external phase of the transposition, we notice that the noosphere follows a pattern in the presentation of the content, associating the ionic bond stabilization with the octet rule, which is a biologically aged content (LIMA et al., 2018) in the students' learning, as Bodner (1991), Taber (1994) and Toma (1997) affirm. Regarding the analysis of the internal phase of transposition, we noticed that teachers usually follow exactly what is proposed in textbooks, which sometimes present concepts far too far from wise knowledge, and ends up transposing this information to the students in a teaching process and learning. From this, it was possible to identify all the elements in the external and internal phase of the transposition, and we emphasize the importance of the teacher in maintaining an epistemological vigilance, in order to reduce the distance between the three spheres of knowledge, transposing information more coherent with the which is scientifically stated, for students.
