When a teacher ditched screens, class got harder. That may be why it worked.

Seventh-grade math teacher Dylan Kane eliminated educational technology from his classroom and discovered that the harder work of face-to-face instruction produced measurable results.

Kane removed all screens and digital tools, replacing them with traditional methods. Student engagement shifted. Rather than passively consuming content through apps and platforms, students faced direct instruction and real-time problem-solving demands. The immediate difficulty of this approach appears to have driven deeper learning.

The experiment reflects a broader reassessment of ed-tech in schools. Educators and policymakers increasingly question whether decades of device expansion actually improved outcomes. Research has documented concerning patterns: students distracted by notifications, reduced retention from reading on screens versus paper, and diminished classroom interaction as tech created barriers between teacher and learner.

Kane's experience aligns with emerging data about cognitive load. When students work through math problems with a teacher present, asking questions and receiving feedback without technological intermediaries, they engage different brain pathways than when swiping through digital modules. The friction of traditional learning—the challenge of raising your hand, the vulnerability of making mistakes aloud, the need to ask clarifying questions—activates deeper processing.

This does not mean all ed-tech fails. Digital tools serve genuine purposes in special education, accessibility, and specific skill drills. But the assumption that more screens equal better schools has proven false.

What Kane's classroom reveals is that effective teaching requires cognitive struggle. When learning feels easy because a platform gamifies content or personalizes it automatically, students often learn less. The productive difficulty of a teacher explaining a concept, a student wrestling with it, and both working through confusion together produces retention.

Schools nationwide are reconsidering blanket tech adoption. Some districts reduced device spending after discovering that one-to-one device programs did not close achievement gaps. Others found that eliminating distracting notifications improved test scores.

Kane's documented results matter because they come from a real classroom
