Prácticas docentes, condiciones de enseñanza y posibilidades de aprendizaje inicial de la lengua escrita
El objetivo de este trabajo es explorar la relación entre las prácticas utilizadas por los docentes para enseñar a leer y a escribir en el inicio de la escolaridad y las oportunidades de aprendizaje. Se realiza un análisis cualitativo de una serie de tareas !levadas a cabo en aulas donde desarrollan tres tipos de prácticas diferentes -instruccionales, multidimensionales y sítuacionales-. Los resultados muestran que estas prácticas difieren en cuanto al tipo de tareas llevadas a cabo; en cuanto a las dinámicas desarrolladas para !levar/as a cabo; en cuanto a los contenidos de lectura y escritura trabajados y en cuanto a los materiales utilizados. Muestran, asimismo, que determinados rasgos q…
The C-12 and C-20 configurations of some neo-clerodane diterpenoids isolated from Teucrium species
Abstract A convenient and conclusive method for determining the C-12 stereochemistry of neo-clerodan-20,12-olide derivatives, even when only one epimer is available, is by 1H NMR NOE measurements. The C-12 configuration of 26 neo-clerodane diterpenoids isolated from Teucrium species has been re-examined by using this type of experiment. The results indicated that all the previous assignments were correct, except for teupyreinin, where the previously assigned C-12(S) configuration must be amended to C-12(R). This was confirmed by chemical transformations and additional 1H and 13C NMR studies. Furthermore, the NOE experiments allowed the assignment of a C-20(S) configuration for teuflavin, th…
