Resumen de Mistake of Having Students Be Mendeleev for Just a Day.
The development of a deep conceptual understanding of the periodic table�its structure, relationships, and utility�is one of the key objectives in an introductory chemistry course. However, there is a difference between recognizing that objective and creating curricular materials to meet that objective in a pedagogically sound manner.This article begins by discussing several of the conceptual features underlying a genuine understanding of the periodic table. Doing so definitively shows that building up such a conceptual understanding in students is an enterprise for which teachers must be willing to devote several days of class time. With this in mind, the article then describes a set of activities focused on promoting such awareness in students using the FERA (focus, explore,reflect, and apply) learning cycle model. All of the materials for implementing these activities are provided in the Supplemental Material.
