Is teaching a fractal?

This work arises from the reflections of a group of teachers. These reflections have led us to analyse the different perspectives of the student and the teacher facing the reality that takes place in the classroom, dealing with aspects such as motivation and student work, classroom overcrowding and design of training activities. As a result of this study, a teaching model based on the principles of fractal geometry is proposed, in the sense that they present different levels of abstraction for the various training activities and the activities are self-similar, that is, they are decomposed again and again. At each level, an activity decomposes into a lower level tasks and their corresponding evaluation. With this model the immediate feedback and the student motivation are encouraged. The presented model is contextualized in a course of introduction to programming but it is fully generalizable to other subjects.
