Screen Time and Tech in Schools Debate

Districts continue balancing phone-free or reduced-tech learning with AI, VR, AR, simulations, virtual labs, commercial materials, and educational apps. A recent lower-secondary hydraulic robotic-arm study found gains in problem solving, design performance, and redesign competence with AI scaffolding, but its quasi-experimental design leaves questions about causality, equity, teacher oversight, and age-appropriate implementation. Mystery Science's California toolkit adds practical implementation support, but independent outcomes evidence is limited.
