Proven Reasons to Learn a Second Language

Benefits of learning a second language in early childhood
Learning a second language provides a wealth of benefits that go well beyond the simple ability to talk to more people. The benefits of multilingual education affect everything from academic and career success to improved health outcomes.

Here are some of the most interesting reasons to master a second language:

1. Better Working Memory

You don’t have to wait until old age to see the benefits of bilingualism as it relates to memory. Researchers have also found that bilingual children have stronger working memories than monolingual children. This means that they could sort and store memories more effectively and outperform peers on both math and reading comprehension tasks.

2. Improved Decision-Making Skills

Working memory is a big part of overall executive functioning—the part of the brain responsible for breaking down tasks and making decisions. Some fascinating studies have revealed that people tend to make more logical decisions when doing so in their second language. This appears to be because there are more emotions tied into a first language, while thinking through a problem in a second language provides some needed time and distance to tackle thorny problems.

3. Enhanced Academic Achievement

Given the memory and decision-making boost, it’s not surprising that bilingual children perform better on standardized tests than their monolingual peers. Years of research on the subject has demonstrated that learning a second language increases first-language skills and improves students’ ability to hypothesize in science, as well as perform better on the SATs and get better grades in college.

4. Increased Earnings and Career Advancement

Finally, all of the benefits of learning a second language lead to better outcomes for adults in their careers. One study estimates that bilingual workers can expect to earn 10 to 15% more on the job. Additionally, Fortune 500 companies tend to target bilingual college graduates in hiring because they understand the value these employees bring to the table.

Of course, mastering a second language takes many years, so it pays to start as early as possible. Children who begin language learning as part of their early childhood education stand to make quick gains and achieve real fluency—a lifelong gift that keeps on giving. Whether you’re looking to provide your child the peace of mind of a steady income, a healthier and more resilient brain, or simply the joy of being able to connect with people in other cultures, language learning just might be the key to their future happiness and wellbeing.

Combining a quality early childhood education with a Spanish immersion program gives our students a leg up in their education and their lives. For parents who value multilingualism – beginning their child's formal learning with an immersion preschool is a natural fit. During this time, children’s brains are hard-wired for language learning and pick it up naturally. Bilingual children expand their awareness of the world and gain significant cognitive benefits. For students from Spanish-speaking homes, a Spanish-immersion education helps keep the family’s cultural heritage alive. There are many benefits of multilingualism and we are proud to support our students on their journey.
