Notes de l'éditeur
- Falar das limitações
- That is very interesting but there’s no guarantee that the stories that will emerge are interesting and meaninfull...

- Is a conceptual methafor to visually represent an EN. Hills represent dramatic situations that in our context means situated context related to competence learning.
