Diseño didáctico accesible de la tabla periódica para población ciega y de baja visión

Abstract

The main objective of this research project is the construction of an accessible didactic design of the periodic table, which allows the learning of its structural form, in contexts of population diversity in the regular classroom, worked with a focal group of 18 students in a high school disability status at the OEA District educational institution. There was realized a design that comprises 2 parts, the first one is a primer that contains relevant data such as the name, symbol, atomic number, atomic weight, oxidation states, electronegativity, group, period, status and application, which also includes an image Allusive is in ink and Braille the second part are 5 arrays on paper Braillon, containing sketch of the Periodic Table representing some properties. For the construction of this design, were used as instruments of data collection, the semi structured interview, the participant observation, the panel and the documentary analysis. The results show the lack of suitable teaching materials in the area of chemistry for secondary education. It concludes that the process of creating educational materials based on the design is an accomplice to different entities educational, as are teachers in the area of chemistry, typists, mediators, students, parents, as well as teachers in training to propose tools that complement and improve the different materials that are to participate in the educational process.
