In memoriam

In the late 70s our dear young teacher Andoni Garritz Cruz agreed to write to Diana and me (then his assistant and friend of her) a small book Conceptual Quantum Mechanics that is called for Chemicals. The final text, 155 pages, was published in 1979, and I tried it with our 3 groups of physical chemistry course I, only to realize how important and incomplete it was. Since then, we spent many nights wrapped in clouds of smoke many cigars they smoked, as was common at that time. we passed many nights discussing how this could be improved small book, about what students should learn. We spent many nights studying and writing by hand, as it was also common at the time. We had dinner, laugh (who knew Diana will certainly remember his laugh) we discussed. Andoni had just finished his doctorate in theoretical chemistry and it was already emerging as a certain reviewer and corrector.

Design of contextualized teaching-learning sequences: Application to learning a theoretical model for the atomic structure

Iván Marchán-Carvajal, Neus Sanmartí Puig

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 keyideas to be applied. As an example of this, the design of a teaching unit is shown for an atomicmodel that takes into account a possible scenario of progression in their learning
