The aim of this paper is to present an educational proposal with didactic and pedagogical orientations, to the Science Education for people with visual impairments. Then, we use as main reference, Gérard Vergnaud’s Theory of Conceptual Fields, joining with a translational focus, applying empirical results of Cognitive Neuroscience. Within this, we highlight the role of educational activities related with 'multisensory scientific literacy ', focusing on the linguistic triad: read, interpretation and textual representation. We hope this perspective, become in the future an important component on guidelines for composing a 'semiotic protocol' for Science Education. Realizing too, epistemological peculiarities, pedagogic and didactic specificities in this area, and, revealing such properties on the cognitive constructs, for science and technology education.

In this work we study extra dimensional theories, taking emphasis in braneworld models generated by real scalar fields. Firstly, we revise the Randall-Sundrum models and we discuss about some thick braneworld scenarios already considered in the literature. We introduce a new thick brane model in order to address the Standard Model hierarchy problem. Furthermore, we show that there exists a class of scalar fields models which are very interesting for analytical studies of thick brane scenarios. Finally, we analyze the braneworld consistency conditions in the context of f(R) and Brans-Dicke gravities, where we show that it is possible to evade a no-go theorem regarding thick brane scenarios
