A preschool teacher who speaks Spanish will introduce Spanish culture to your child. Though your child is still young, she will learn about foreign countries, new festivals and different customs. The teacher will enhance the curriculum with holidays such as the Dia de los Muertos, or Day of the Dead Festival, around Halloween. The teacher may offer the students Latin food to try, such as Mexican wedding cookies or tamales. Learning about foreign cultures opens up a child's mind to new experiences and ideas.
Spanish is an important language to learn, and a Spanish preschool teacher can introduce key phrases, numbers, colors and songs in Spanish. Younger children can learn new languages more easily than adults, or even older children. In 2010, according to the "Boulder Weekly," 47 million Hispanics lived in the United States. A preschooler with Spanish language skills will have an advantage of understanding this popular language, which will be important in the marketplace as he becomes an adult.
Scientists who have studied the brains of bilingual children have found improved memory functions. According the the Society for Neuroscience, bilingual preschool student had better focus than children who only knew one language. The bilingual children could tune out distractions more easily. Moreover, adults who were bilingual at an early age also had better concentration skills than adults who were monolingual. Preschool children are young enough to learn new languages fluently.
Speaking more than one language may have important health benefits as well. According to the Society for Neuroscience, researchers have found that bilingual adults may delay the onset of brain diseases such as Alzheimer's and dementia for up to four years. Brains of bilingual adults have denser gray matter. This gray matter is the area where nerve cells and fibers are processed. Adults who learned a second language before age five enjoyed the greatest advantage. Also, understanding two languages may increase blood flow and oxygen to the brain itself.
