Are we digitizing education at the expense of our children’s physiological well-being?
A coalition of UK clinicians has sounded the alarm: rampant classroom screen time is directly fueling a surge in pediatric health crises, notably severe myopia, musculoskeletal strain, and chronic sleep disruption. While schools race to achieve one-to-one device parity, medical experts are now urging strict limits on digital exposure.
From an IT and EdTech architecture perspective, this highlights a critical flaw in current implementation strategies. In educational technology, the SAMR model emphasizes using tech to *Modify* and *Redefine* learning, not merely *Substitute* physical media with glowing displays. Swapping a textbook for a tablet without re-engineering instructional ergonomics is not innovation; it is a superficial upgrade that violates Mayer’s Cognitive Load Theory and basic human-computer interaction (HCI) standards.
When hardware deployment outpaces health governance, technology shifts from an empowering catalyst to a biological liability. Are our educational institutions mistaking sheer screen exposure for genuine digital literacy? As technologists and educators, should we enforce mandatory analog-digital hybrid ratios in modern curricula, or rely on software-level ergonomic throttles?

我們是否正在以犧牲下一代的生理健康為代價，盲目推動教育數位化？
英國臨床醫學專家近日發出嚴正警告：課堂中過度且缺乏節制的螢幕使用，正直接導致學童近視率暴增、骨骼發育不良以及慢性睡眠障礙等長期健康危機。在各級學校競相追求「生生用平板」的同時，醫療界已大聲疾呼必須嚴格限制課堂螢幕時間。
從 IT 與教育科技（EdTech）架構的角度來看，這暴露出科技導入過程中的致命盲點。在教育科技的 SAMR 評估模型中，技術的核心價值在於「重塑（Redefine）」學習體驗，而非單純「替換（Substitute）」紙本書籍。若僅將印刷品換成發光螢幕，卻忽略人機互動（HCI）與人體工學規範，不僅有違梅耶的認知負荷理論（Cognitive Load Theory），更不是真正的數位素養教育。
當硬體部署凌駕於生理健康之上，科技便從「認知賦能」淪為「生理負擔」。我們是否誤將「盯著螢幕的時間」等同於「科技競爭力」？面對不可逆的數位浪潮，學校應否強制規範螢幕使用上限，回歸動靜整合的混成教學？歡迎在下方留言分享您的觀點。
