Reflexión sobre el trabajo experimental planteado como investigación con docentes de Ciencias Naturales

We consider that the process carried out in the classroom by teachers of Natural Sciences is enriched when the use of diverse resources is at stake. We present a proposal applied with physics, chemistry and biology teachers, which incorporates the use of cell phone and activities with texts to the practical laboratory work (tpl). The methodology includes the development of a workshop with instances of reflection of the participants. The results show the need to make changes in the way in which the tpl are developed assiduously, updating the proposals based on the results of the educational research in Natural Sciences.
