Nesta nova entrada vouvos presentar a miña proposta para a actividade que
Ana Fontenla nos suxeriu o pasado 2 de febreiro na aula. Xa que estivemos
traballando CLIL, a idea era deseñar unha actividade para traballar outra
materia. Aquí vai a miña:
Trátase dunha actividade de comprensión, destinada a traballar a materia de
bioloxía con alumnos de 4º da ESO e consiste nunha comprensión lectora sobre os
descubrimentos de Gregor Mendel. Para levar a cabo a actividade, os estudantes organízanse
en grupos de catro ou cinco persoas. Antes de comezar, pódeselles preguntar aos
alumnos se saben quen foi Gregor Mendel e de que pensan que pode tratar o texto
ou como pensan que podería estar organizado. A continuación, cada grupo recibe varios
anacos de papel con fragmentos do texto desordenados. Entre os membros do grupo
deben encargarse de lelos en voz alta e ordenalos correctamente para conformar o
texto completo. Algunhas ideas sobre como dividir os fragmentos:
E este sería o texto completo:
Father of Genetics
Gregor Mendel, through his work on pea plants, discovered the
fundamental laws of inheritance. He deduced that genes come in pairs and are
inherited as distinct units, one from each parent. Mendel tracked the
segregation of parental genes and their appearance in the offspring as dominant
or recessive traits. He recognized the mathematical patterns of inheritance
from one generation to the next. Mendel's Laws of Heredity are usually stated
as:
1) The Law of Segregation: Each inherited trait is defined by a gene
pair. Parental genes are randomly separated to the sex cells so that sex cells
contain only one gene of the pair. Offspring therefore inherit one genetic
allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for different traits are
sorted separately from one another so that the inheritance of one trait is not
dependent on the inheritance of another.
3) The Law of Dominance: An organism with alternate forms of a gene
will express the form that is dominant.
The genetic experiments Mendel did with pea plants took him eight years
(1856-1863) and he published his results in 1865. During this time, Mendel grew
over 10,000 pea plants, keeping track of progeny number and type. Mendel's work
and his Laws of Inheritance were not appreciated in his time. It wasn't until
1900, after the rediscovery of his Laws, that his experimental results were
understood.
Para rematar, podémoslle volver a preguntar, por exemplo, cales foron os
elementos do texto que lles axudaron a ordenar a información. Deste xeito, traballamos
a súa comprensión lectora ao tempo que aprenden contidos e vocabulario relacionados
coa materia de bioloxía.
