Application of Didactic Strategies as Multisensory Teaching Tools in Organic Chemistry Practices for Students with Visual Disabilities
(American Chemical Society, 2019-04)
Visually impaired or blind students require adjustments to the traditional hands-on activities and methodological and didactic strategies employed by the teacher. These adaptations are based on multisensory teaching tools, ...
Comparative study of the optical behavior of a porphyrin encapsulated in sol-gel silica coatings and in solution as a function of pH
We report a comparative optical spectral study as a function of pH on a porphyrin encapsulated in a solgel matrix and in methanol solution. Its response has been discussed in terms of pH-sensitivity as a function of the ...
Observation and inference in chemistry teaching: a model-based approach to the integration of the macro and submicro levels
The aim of this article is to propose a didactical approach to establish appropriate relations between different kinds of chemical knowledge and explanations at the macro and the submicro level. Incorrectly moving between ...
