MODEL A + + A (A but Strategies but Aprendientes) This devised didactic model, designed and that comes being put in practice in the School Our Lady of the Candlemas in the classes of mathematics in seventh degree indicates, us that in the process of education-learning lived to the interior of the classroom she is due to journey at least by five moments: i) Conceptualizacin II) Reinforcement of concept III) Application of that concept, and IV) Transference v) Evaluation Mobilizing for every moment the strategies that are to him pertinent and necessary in order that ALL the students have the opportunity to participate in the process. Strategy that it does not like to the one it will like to the other. The teacher has come working using only the model from the traditional class (there are exceptions). Title, new paragraph, definitions, examples, exercises, task. This SINGLE one strategy IS NOT SUFFICIENT to guarantee that the different forms to think and therefore to learn, they are aligned with him. If in a hall class there are 40 students, at least, we could suppose that four or five ways different exist to think and that each of these demands a strategy (theory of the total brain). In this model, " clave" it is in spurting and to inside practice the greater number of strategies for every moment consequently the context of the mathematical probalidades, we could assure that ALL appropriate and have been journeyed by the moments that are demanded so that reconstructed knowledge is coherent and consistent. The 40 students of the classroom form a WHOLE to which the teacher as professional she faces and she serves his and if in that WHOLE it is discovered that situations exist that prevent the harmonic development of l, it is not another alternative that to take part in that or those centers of difficulties trying of which that WHOLE works.
