When Should AI Be Used in the Classroom? Learning Science Offers a Guide

In the face of rapid technology change, our students’ future careers may look nothing like the jobs we know today. Sitting in classrooms and learning facts rather than developing cutting-edge tech skills can feel like wasted time. And yet there is significant pushback on technology in schools, including one-year AI bans in the nation’s two largest school districts.

District and state policies run the gamut from embracing to banning AI. This raises a key question: When does AI accelerate student learning and when does it interfere?

Learning science over the past 60-plus years provides a clear answer. Evidence shows learning is both context-specific and cumulative. Every subject has its own fundamental vocabulary and rules. Only after learners have foundational knowledge are they ready to solve simple problems. This is followed by a virtuous cycle of accumulating greater subject knowledge and skills and solving more complex problems. Supporting students who are still in the phase of acquiring foundational knowledge is fundamentally different from supporting learners in later stages of mastery. 

School curriculum is intentionally designed so students sequentially build prerequisite skills. For example, third-grade reading comprehension relies on word fluency and phonics learned in prior grades. Algebra relies on operations fluency, number sense, and fractions skills developed in middle school. Advanced placement history relies on knowledge of U.S. history facts and the context that connects them, along with strong reading comprehension and writing skills.

A Clear Red Line Against AI, Sometimes …

Recent guidance from experts such as the American Psychological Association cautions against blanket rules because “Research to date shows that EdTech tools are not inherently beneficial or harmful to learners. The effects depend on what an EdTech tool asks the learner to do, how adults integrate it, and the age and needs of the child, and what it replaces.”  

As the founder of an ed tech company which uses objective cognitive data on memory, complex reasoning, executive functions, and flexible thinking to implement science of learning best practices, I could not agree more.

Within what we call the Learning Loop, the early section — where students build knowledge, store it in memory, gain basic understanding, and solve simple problems —I s particularly important. It is also often tedious, sometimes hard, and rarely fun. It is also where AI excels. No human comes close to AI tools’ ability to store and retrieve information.

Even the most capable students can tire or struggle in the early loop. It is easy to understand why they would want to have AI replace the most tedious tasks, but that is exactly when we cannot allow AI to substitute for students doing the “brainy work” themselves.

Study after study shows there is no shortcut to mastery. Students must do the (sometimes tedious and hard) early learning on their own. Learning science supports limiting students’ independent use of AI in core subjects until after they have at least achieved proficiency. 

The Fuzzier Transition from Proficiency to Mastery

While there is a clear red line when students should not be using AI in the early loop, the line gets fuzzier in the transition from proficiency to mastery.

Once foundational knowledge and skills are established, the goal shifts to mastery. Using AI’s endless knowledge to accelerate students’ learning at that point can be beneficial.

For example, using AI to write a student’s first five-paragraph essay would be disadvantageous because they need to experience the productive struggle in order to fully understand how to write a clear thesis statement, supporting proof points, and a strong conclusion. In contrast, a student who has written many five-paragraph essays should be allowed to use AI to refine their rough draft, thinking through specific prompts such as identifying better concrete examples.

Teachers can exercise professional judgment on where to draw the line within the Learning Loop based on their students’ age, the subject, and the quality of ed tech tools available.

Preventing proficient students from using AI could limit their growth — and their enthusiasm for school. This is why schools should avoid blanket restrictions and age-based rules around AI use and consider the context.

Using Data to Inform AI Policies

There are plenty of strong use cases for proficient students to interact independently with AI directly. And there are also cases where teachers can use AI with students who are not yet proficient to support instruction. For example, using high-quality AI-assisted programs for literacy screening can be incredibly efficient, particularly where there is a shortage of trained reading specialists. In contrast, relying on AI for a diagnosis or to teach a young student struggling with literacy would be a misuse. 

While blanket rules for AI use will not work, science-informed practices combined with structured, data-informed decision-making will. It is important to have a mechanism — such as standards-based grading — to accurately track students along the continuum to mastery so teachers know when and how to allow or encourage AI-assisted programs or generative AI use.

Most of the K-12 debate on AI has focused on which products are helpful to improving outcomes and which products may be harmful. Instead of delaying decisions while awaiting well-designed product efficacy research, which can take years, teachers need guidance now.

Decision-makers already have the evidence from learning science and the comprehensive data about student performance to create thoughtful, effective AI policies about when (post-mastery) and when not (pre-proficiency) to use AI. There are times when a proficient student can and should use AI, and in those cases our teachers, the subject-matter experts, can be equipped and empowered to exercise the best judgment.
