The scientific competences point to the development of capabilities, abilities and aptitudes which help to solve problems according to the context where the facts take place. Referring to PISA, 2015 there are six levels of performances to develop scientific competences. The main purpose here is for the students to identify, explain, and put into practice consciously the scientific knowledge, and as well the knowledge about Science in a great range of possibilities, somehow complex or easy circumstances. Besides being able to use this knowledge, they can also use arguments, and apply some recommendations on how to make logical decisions. At the same time, they could show abilities to solve some daily problems analyzing, comparing and making relations among different difficult situations related to composition, isomery, and structures of chemical compounds.
In this paper a proposal is made for teaching Chemistry through classes designed to learn the spatial structures, nomenclature and isomery of organic compounds. Some workshop plans have been included to represent the chemical compounds (formulae) and their spatial structures. Most important is the opportunity the students have to manipulate spatial structures in 3D.

Moving towards an education which develops competencies in the classroom-a current challenge
Pineros, V.; Moreno-Mediavilla, Daniel (1); Pascual López, Virginia (1); Palacios, A. (1) (Edulearn17:8TH international conference on education and new learning technologies, 2016)The term "competence" is already known in a business context and it is associated with the concept of quality. In regards to education, it has been used since 1992 and has been widely accepted in this field. Unfortunately, ... -
Polymeric chemosensor for the colorimetric determination of the total polyphenol index (TPI) in wines
Vallejos, S.; Moreno-Mediavilla, Daniel (1); Ibeas, Saturnino; Muñoz, M. Asunción; García, Félix Clemente; García, Jose M. (Food Control, 12/2019)We have developed a new method for the rapid and inexpensive determination of the total polyphenol index (TPI) in wines by simply immersing our sensory film in red or white wines and visually checking the colour change ...
