What if some of the things we were taught about language teaching are not really how language acquisition works?
That was the heart of this conversation with Dr. Bill VanPatten, which was originally livestreamed in the IFLT Facebook group as part of CI Reboot. And honestly, this conversation was such an honor for me because Dr. VanPatten’s work has deeply shaped the way I understand language acquisition, input, communication, and what it means to teach for proficiency.
His books, his podcast, and his sessions have helped so many language teachers move away from teaching about the language and toward creating classrooms where students can actually acquire language.
In this conversation, Dr. VanPatten talked about two foundational myths in second language acquisition. There are more than two myths, as he reminded us, but he chose these two because they are critical if we want to understand what we are doing in our language classrooms.
And for many of us, these myths matter because they are connected to everything: grammar instruction, textbook expectations, assessment, curriculum pacing, student output, and even the way we advocate for our programs.
Myth 1: Learners internalize rules, patterns, and sounds
The first myth Dr. VanPatten addressed is the idea that language learners internalize rules, patterns, and sounds.
He said learners do not internalize rules. They do not internalize patterns. They do not internalize sounds.
Why?
Because, as he explained, those things we call rules, patterns, and sounds are not really what language is. They are more like an illusion.
He used the metaphor of constellations. When we look at the sky from Earth, we see constellations. They look real to us because of our perspective. But if we traveled out into space, those constellations would disappear. They were not really there in the way we thought they were.
That is how he explained grammar rules and patterns. They are what we think we see when we look at language from the outside. But that does not mean those rules exist in learners’ heads in the way a textbook chart suggests.
This is hard for many of us because we were trained to think about language as rules. We were trained to explain rules, practice rules, and then assess whether students could use those rules.
But according to Dr. VanPatten, that is not what acquisition is.
Learners are not copying rules from the input they hear or read. Instead, their developing language system grows over time as it extracts pieces of data from the input.
The linguistic acorn
One of the metaphors Dr. VanPatten used was the idea of an acorn becoming an oak tree.
An acorn does not become an oak tree overnight. It needs water, nutrients, sunlight, and time. Everything needed for the oak tree is inside the acorn, but it needs the right conditions from the environment to grow.
He said we can imagine that learners have a “linguistic acorn” in their heads. That acorn needs the right kind of input: comprehensible input embedded in communicative situations.
Over time, the system grows. It does not grow because we explain a rule and students internalize it. It grows because the developing system receives input, extracts pieces of data, and changes little by little.
That image is so helpful because it reminds us that acquisition is not instant. It is not linear. It is not a chart. It is growth.
And growth takes time.

Myth 2: Children and adults acquire languages differently
The second myth Dr. VanPatten discussed is the idea that children and adults acquire languages in fundamentally different ways.
He explained that, at their core, first and second language acquisition are fundamentally similar. What happens linguistically and psycholinguistically as language grows in the mind is not fundamentally different for adults and children.
The differences are mostly external.
Adults and teenagers have different expectations. They may feel pressure to sound smart, accurate, or adult-like. They may impose unrealistic expectations on themselves. Teachers may also impose expectations on teenage learners that we would never impose on young children.
When a little child says something incorrectly, we often celebrate the communication. But when a 14-year-old student says something that is not accurate, many of us feel tempted to correct immediately because we think the correction will help.
But if the learner’s system is developing in stages, constant correction does not change the way acquisition unfolds.
This is why the myth matters so much. If we believe adults and teenagers acquire language in a completely different way from children, we may think they need grammar explanations, constant correction, and practice in order to acquire. But Dr. VanPatten explained that the core process of acquisition is still driven by input and interaction.
Acquisition is not effortless
One of the points that stayed with me from this conversation was when Dr. VanPatten talked about the idea that children acquire language “effortlessly.”
He challenged that idea by reminding us how much input children actually receive.
A child may hear language for many hours a day and still take about a year before words begin to appear. Later, children move into two-word combinations. Sentences come much later. By the time children are five, they have had thousands and thousands of hours of input and interaction, and they are still not adult-like speakers.
So when we say children acquire language effortlessly, we may be missing the amount of time, input, and interaction involved.
This matters in our classrooms because our students do not have thousands of hours with us. They may have a few hours a week. And yet we often expect fast, accurate production.
That expectation can create frustration for students and teachers.
Why traditional explanation plus practice does not lead to acquisition
In the conversation, Dr. VanPatten made a strong point: if the goal is acquisition, traditional explanation plus practice does not move acquisition forward.
He contrasted that with CI approaches, where compelling topics, stories, and tasks encourage acquisition because learners are receiving comprehensible input in communicative contexts.
This is important because many teachers are trying to make a shift, but they are still being asked to follow curriculum maps, textbook chapters, pacing guides, benchmarks, and assessments.
That creates a real tension.
Many teachers ask: How can I use comprehensible input to teach the present tense? How can I use comprehensible input to teach the subjunctive? How can I use comprehensible input to teach object pronouns?
Dr. VanPatten explained that this question comes from the same myth: the idea that learners internalize the grammar we are trying to teach.
If we try to teach the same explicit grammar content “through CI,” we are still assuming that the point of the input is for students to internalize that rule. But according to Dr. VanPatten, acquisition and explicit learning are different and rules do not exist the way we think about them.
The learner’s developing system is not building a textbook chart in the brain. It is building a linguistic system over time.
What about textbooks, standards, and teacher preparation?
One of the hardest parts of this conversation was the question of why these myths are still so present in language classrooms.
Dr. VanPatten talked about teacher education and how, in many programs, language teachers may take many general education courses and only one course focused specifically on language teaching. In that one course, there may be a strong focus on standards, guidelines, and how to work with textbooks, but not enough focus on language acquisition or the nature of language.
He also explained that many university language departments are really literature and culture departments, not departments centered on language acquisition or linguistics.
That creates a cycle.
Teachers may not receive enough preparation in language acquisition. Then they enter systems where textbooks and pacing guides shape instruction. Then the same assumptions continue.
This is why he emphasized education and advocacy.
Teachers need to understand the basic facts of language acquisition so we can explain them to administrators, parents, students, and colleagues. Not because we want to win an argument, but because we need people to understand what we are trying to do and why.
A realistic starting point: hybrid teaching
One of the most practical parts of the conversation was when Dr. VanPatten talked about what teachers can do when they are required to follow a traditional curriculum.
He did not pretend this is easy.
Instead, he suggested a possible transition: separating explicit instruction from acquisition-driven work instead of trying to turn the textbook grammar chapter into CI.
For example, a teacher might do a period of traditional instruction because the system requires it, and then a separate period focused on comprehensible input, stories, tasks, and interaction.
The important part is not to confuse the two.
The explicit side may satisfy certain curriculum or grading requirements. The CI side gives students opportunities for input and interaction that support acquisition.
He also pointed out that when students experience the CI side, they may begin to recognize that they are understanding more and communicating more. That can create buy-in from students because they feel the difference.
Assessment: Focus on what students can do
Another big part of the conversation was assessment.
If students acquire at different rates and in different stages, then how should we assess?
Dr. VanPatten suggested that we need to think locally. Different teachers have different contexts. Some teachers see students every day. Some see them a few times a week. Some have small classes. Some have 45 students. Some teach in semester schedules. Others teach year-long courses.
Because the contexts are different, assessment expectations also need to be realistic for the local context.
He also encouraged us to think about what students can do, not just what they know.
Can they understand a story?
Can they answer questions about what they hear?
Can they comprehend more than they could before?
Can they communicate meaning, even if they are not accurate in every form?
This matters because comprehension is not a small thing. As Dr. VanPatten reminded us, comprehension is the first step toward communication. If students cannot comprehend, they cannot respond in a meaningful way.
Why teachers need to become advocates
Throughout the conversation, one idea came up again and again: teachers need to be able to explain what acquisition is and how it happens.
That does not mean we all need to become researchers. But we do need to understand enough to advocate for our classrooms.
Dr. VanPatten mentioned several of his books as accessible resources teachers can share with department chairs, administrators, and colleagues. He specifically mentioned books such as While We’re on the Topic, The Nature of Language, and Language Acquisition in a Nutshell.
These are the kinds of resources that can help us have better conversations in our departments and schools.
Because sometimes the problem is not that people disagree with acquisition-driven teaching. Sometimes they have never been given a clear explanation of how language acquisition actually works.

Dr. VanPatten’s books for Spanish learners
Toward the end of the conversation, Dr. VanPatten also shared about his writing for Spanish learners.
He talked about Cuentos cortos, his flash fiction stories written for language learners. These stories are short, under 500 words, and include input-based tasks.
He also talked about discourse scrambles, where students take sentences from a story summary and put them in order. He explained that this kind of task can still provide comprehensible input because students have to process meaning in order to organize the sentences.
This connected beautifully with the larger message of the conversation: students need opportunities to process language for meaning.
Final Thoughts
This conversation gave us a lot to think about.
If we want students to acquire language, we have to understand what acquisition is and what it is not.
It is not the internalization of grammar rules.
It is not fast.
It is not the same as explicit learning.
It does not happen because students practiced a chart enough times.
Acquisition grows over time through comprehensible input embedded in communicative contexts.
And for us as teachers, that means we need to keep learning, keep asking hard questions, and keep advocating for the kind of instruction that helps students understand and communicate.
Not perfectly.
Not all at the same pace.
But with growth.
And that is what this work is really about.
