Construyendo puentes conceptuales entre las varias escalas y dimensiones de los modelos químicos Authors Vicente Talanquer Abstract This paper describes some of the difficulties that chemistry students face when trying to connect concepts and ideas across the different scales and dimensions, from which many chemical models are defined. We also discuss some of the features of traditional chemistry education that tend to aggravate these problems, and we present a set of computer- based educational tools, which are designed to scaffold learning in this area.
