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

Dylan Kane, a seventh-grade math teacher, removed all screens from his classroom and found that the difficulty increase actually drove better learning outcomes.

Kane abandoned educational technology entirely, replacing digital tools with paper, pencils, and traditional instruction. The shift forced students to engage more directly with math concepts rather than relying on automated feedback systems or interactive software. Without screens, students had to grapple with problems longer, ask more questions, and develop deeper problem-solving strategies.

Teachers and researchers have increasingly questioned whether ed-tech integration delivers on its promises. While technology companies market their products as personalized learning solutions, studies show mixed results on actual achievement gains. Students often become dependent on immediate digital feedback rather than learning to tolerate the cognitive struggle that builds mathematical thinking.

Kane's experiment reflects a broader shift in education. Some schools are scaling back screen time after pandemic-era remote learning exposed limitations of technology-dependent instruction. The American Academy of Pediatrics recommends limiting screen exposure for children, citing concerns about attention span and social development.

The harder classroom experience Kane created had unintended benefits. Students worked through problems without automated hints, collaborating with peers to find solutions. They wrote out their thinking on paper, making errors visible and correctable. Teachers observed students asking more substantive questions and developing metacognitive awareness of their own problem-solving processes.

This pattern matches cognitive science research. When learning feels effortful, brains encode information more deeply. Fluency with screens can mask shallow understanding. Students click through content quickly, but retention suffers.

Kane's experience does not argue against all technology in schools. Rather, it highlights a design problem. Many ed-tech tools prioritize engagement and speed over cognitive demand. They remove productive struggle instead of scaffolding it.

The lesson for educators and administrators: harder does not always mean worse. Classroom difficulty, when carefully structured, often correlates with learning gains. Kane discovered that
