ROTAECHE GUERRERO, Rosa Araceli  and  MONTIEL ESPINOSA, Gisela. Angle Concept Learning in Mexican Junior High School Students. Educ. mat. [online]. 2017, vol.29, n.1, pp.171-200.  Epub Feb 14, 2022. ISSN 2448-8089.  https://doi.org/10.24844/em2901.07.

We present on this paper a didactic experience which main goal was students learning the concept of angle. To achieve it a design was conducted by a Didactic Engineering. The preliminary analysis integrates previous research results that highlight specificity of didactic phenomena associated to the school concept of angle, and some historic and didactical considerations.

Even when the didactic experience was satisfactory for the teacher and her students, from an initial evaluation is concluded that the school concept of angle is not "learned" in a formal and absolute sense, but associated meanings to its nature are developed; so we say students can use angularity in order to interact with their environment.

Keywords : Angle; Meanings of angle; Angularity; Didactic Engineering; Didactic contract.
