Our Story

The Czech proverb,

“As many languages you know, as many times you are a human being.” 

perfectly summarizes the reason we dedicated the last twenty plus years to dual language and immersion education. 


We believe that multiplying the number of languages students acquire while in school might also multiply the number of opportunities they have to experience being human.

But what defines “being human” or the “human experience?”

Many experts agree, what sets our experience apart from other living things is our ability to feel a wide range of emotions and to empathize. To empathize means we can imagine and identify with the thoughts and feelings of others. The experts also agree that empathy is so important because it can lead to compassion. Compassion, in turn, can lead to taking action for the good of others, a vital part of society and community.

What does language have to do with empathy? 

Though all humans are born with the capacity to empathize, psychologists will tell you that empathy is a learned behavior that needs to be developed. For most humans, language development goes hand in hand with emotional and cognitive development. Just read two essays written by the same student, one from kindergarten and one from twelfth grade and you’ll see what we mean. If one language increasingly expands the ways in which students can express and interpret their own and others’ thoughts and emotions, what does developing two languages do?  As former educators and school leaders in Spanish dual language immersion schools, we had the privilege of observing hundreds of students “do school” in two languages.

Does developing two languages increase empathy? 

Many research studies point to this possibility, but we observed it. Our students seemed to take in new information and consider it from different perspectives. They wrote stories showcasing characters with complex feelings and insights. They also seemed to develop friendships characterized by differences rather than similarities. They showed interest in people who dressed in non-western clothes and spoke different languages, smiling and turning toward such groups during field trips. It was as if our students were expanding their capacity to not simply empathize, but to empathize globally, across linguistic, cultural and ethnic differences.

What happens if the societally powerful language takes over?

But what we had observed in the early years, became less apparent as students moved into upper primary and middle school grades. We began to wonder if the change had something to do with a shift in the way students were using Spanish and English. Whenever possible they used English, the societally dominant language, to interact with content and one another.  Even students who entered the program as balanced bilinguals or as Spanish-dominant participated in what we began calling  “English take-over.” 

We questioned whether or not we were unconsciously, or even consciously sending the message that English was more valuable than Spanish. Our program design meant English instructional time increased dramatically beginning in third grade and continued through secondary. Instruction involved extensive preparation for state standardized testing in English and less focus on Spanish language development. In fact, many teachers believed that students should respond as much as possible in English, even during Spanish instructional time.

What did we learn and do?

As we reflected, we wondered why our program design and instructional practice favored English. After all, research on dual language immersion student outcomes in the United States showed that academic achievement in English wasn’t the issue, minority language proficiency was. Dual language immersion student outcomes on standardized measures in English were similar to or better than that of their peers in traditional educational programs. Minority language proficiency on the other hand was concerning, as it was characterized by grammatical errors and anglicized syntax (structure). 


Based on research, we began developing and implementing program guidelines, instructional frameworks and tools underpinned by teaching practices that allotted more time and energy to Spanish language development.  While English outcomes didn’t waiver, Spanish proficiency increased. Though only anecdotal, teachers also recounted stories that pointed to a resurgence of global empathy. Determined to expand our vision further, we left our roles and founded addalingua, an organization dedicated to empowering teachers to inspire global empathy through dual language and immersion education.

So how did addalingua develop Language First?

Through addalingua we had the privilege of establishing long term relationships with a cohort of schools across the country. Since 2009, they have followed our minority language-centered approach to dual language and immersion education by upholding program standards, participating in a progression of professional learning, and implementing common Spanish instructional frameworks and resources. Because of these relationships, our approach evolved, informed by regular teacher feedback, student data, and countless hours of classroom observations. In 2020, we officially named our approach Language First. And since early 2020, we have adapted the original whole school approach specific to Spanish by making it accessible for individual educators teaching in any minority language. 

By doing so, we’ve expanded our community, inviting all dual language and immersion educators to our website and into our Language First professional learning courses. So, if you believe it’s time to refocus dual language and immersion education on minority language development, join the movement to inspire global empathy! We are confident that by putting the minority Language First, you’ll transform not only your practice, but maybe even your students’ lives.
