MARCHAN-CARVAJAL, Iván  y  SANMARTI, Neus. Design of contextualized teaching-learning sequences: Application to learning a theoretical model for the atomic structure. Educ. quím [online]. 2015, vol.26, n.4, pp.267-274. ISSN 0187-893X.  https://doi.org/10.1016/j.eq.2015.06.001.

This article reflects on the notion of context and its importance in the teaching and learning of science in general and chemistry in particular. A brief review of the various ways of understanding science education in context and problems associated with its application in the classroom is done. From this analysis a proposal of criteria for the development of contextualized learning units is presented, and its goal is to construct a model with the key ideas to be applied. As an example of this, the design of a teaching unit is shown for an atomic model that takes into account a possible scenario of progression in their learning
