Phytosociology of halophilic species from the genus "Tamarix L. (Tamaricaceae)" on the island of Gran Canaria

[EN] Forested Tamarix L. species found in the Canary Islands as in the Western Mediterranean Basin and the Saharo-Arabian area are included in the class Nerio-Tamaricetea within the order Tamaricetalia africanae order recognized by the Canaries that does not include Tamarix africana Poir., and the halophilic and halotolerant their communities are included in the alliance Tamaricion boveano-canariensis with the new partnership Atriplici ifniensis Tamaricetum canariensis endemic to the Canary Islands, which is also poor in the characteristic species of the class and to be defined almost exclusively for Tenerife requires a broader review.

CLIL materials in Secondary Education: focusing on the language of instruction in the subject area of Mathematics

[EN]Applying a CLIL methodological approach marks a shift in emphasis from language learning based on linguistic form and grammatical progression to a more ‘language acquisition’ one which takes account language functions. In this article we will study the elements of the “language of instruction” of the area of Maths in Secondary Education, by focusing on the analysis of the communicative functions, and the lexical and the cultural items present in the textbook in use. Our aim is to present the CLIL teacher with the linguistic and didactic implications that he or she should take into consideration when implementing the bilingual syllabuses with their students. In order to do that, we will present our conclusions emphasizing the need for coordination in different content areas, linguistic and communicative contents, between the foreign language teacher and the CLIL subject one.
